Detailed Description

Defines the functionality of a 3D API.

Remarks

The RenderSystem class provides a base interface which abstracts the general functionality of the 3D API e.g. Direct3D or OpenGL. Whilst a few of the general methods have implementations, most of this class is abstract, requiring a subclass based on a specific API to be constructed to provide the full functionality. Note there are 2 levels to the interface - one which will be used often by the caller of the Ogre library, and one which is at a lower level and will be used by the other classes provided by Ogre. These lower level methods are prefixed with '_' to differentiate them. The advanced user of the library may use these lower level methods to access the 3D API at a more fundamental level (dealing direct with render states and rendering primitives), but still benefiting from Ogre's abstraction of exactly which 3D API is in use.

Member Function Documentation

_addMetrics()

void Ogre::RenderSystem::_addMetrics

(

const RenderingMetrics &

newMetrics

)

_beginFrame()

virtual void Ogre::RenderSystem::_beginFrame ( )

pure virtual

Signifies the beginning of a frame, i.e.

the start of rendering on a single viewport. Will occur several times per complete frame if multiple viewports exist.

Implemented in Ogre::VulkanRenderSystem, Ogre::NULLRenderSystem, Ogre::MetalRenderSystem, Ogre::GL3PlusRenderSystem, Ogre::D3D11RenderSystem, and Ogre::GLES2RenderSystem.

_beginFrameOnce()

virtual void Ogre::RenderSystem::_beginFrameOnce ( )

virtual

Signifies the beginning of the main frame.

i.e. will only be called once per frame, not per viewport

Reimplemented in Ogre::MetalRenderSystem.

_cleanupDepthBuffers()

void Ogre::RenderSystem::_cleanupDepthBuffers

(

)

_clearStateAndFlushCommandBuffer()

virtual void Ogre::RenderSystem::_clearStateAndFlushCommandBuffer ( )

virtual

On D3D11 calls ClearState followed by Flush().

On GL3+ it calls glFlush

Do not call this function while inside rendering internals, as it will clear the device state, thus leaving it inconsistent with what we think it is set to.

Reimplemented in Ogre::D3D11RenderSystem.

_convertOpenVrProjectionMatrix()

virtual void Ogre::RenderSystem::_convertOpenVrProjectionMatrix ( const Matrix4 &  matrix, Matrix4 &  dest  )

virtual

Converts an OpenVR projection matrix to have the proper depth range and reverse Z settings.

Parameters

matrix
dest

Reimplemented in Ogre::GL3PlusRenderSystem.

_convertProjectionMatrix()

virtual void Ogre::RenderSystem::_convertProjectionMatrix ( const Matrix4 &  matrix, Matrix4 &  dest  )

virtual

Converts a uniform projection matrix to suitable for this render system.

Remarks

Because different APIs have different requirements (some incompatible) for the projection matrix, this method allows each to implement their own correctly and pass back a generic OGRE matrix for storage in the engine.

Reimplemented in Ogre::NULLRenderSystem, and Ogre::GL3PlusRenderSystem.

_createRenderWindow()

virtual Window* Ogre::RenderSystem::_createRenderWindow ( const String &  name, uint32  width, uint32  height, bool  fullScreen, const NameValuePairList *  miscParams = 0  )

pure virtual

Creates a new rendering window.

Remarks

This method creates a new rendering window as specified by the paramteters. The rendering system could be responible for only a single window (e.g. in the case of a game), or could be in charge of multiple ones (in the case of a level editor). The option to create the window as a child of another is therefore given. This method will create an appropriate subclass of RenderWindow depending on the API and platform implementation.

After creation, this window can be retrieved using getRenderTarget().

Parameters

name	The name of the window. Used in other methods later like setRenderTarget and getRenderTarget.
width	The width of the new window.
height	The height of the new window.
fullScreen	Specify true to make the window full screen without borders, title bar or menu bar.
miscParams	A NameValuePairList describing the other parameters for the new rendering window. Options are case sensitive. Unrecognised parameters will be ignored silently. These values might be platform dependent, but these are present for all platforms unless indicated otherwise: Key Type/Values Default Description Notes title Any string RenderTarget name The title of the window that will appear in the title bar   colourDepth 16, 32 Desktop depth Colour depth of the resulting rendering window; only applies if fullScreen Win32 Specific left Positive integers Centred Screen x coordinate from left   top Positive integers Centred Screen y coordinate from left   depthBuffer true, false true Use depth buffer DirectX9 specific externalWindowHandle Win32: HWND as integer GLX: poslong:posint:poslong (display*:screen:windowHandle) or poslong:posint:poslong:poslong (display*:screen:windowHandle:XVisualInfo*) OS X Cocoa: OgreGLView address as an integer. You can pass NSView or NSWindow too, but should perform OgreGLView callbacks into the Ogre manually. iOS: UIWindow address as an integer 0 (none) External window handle, for embedding the OGRE render in an existing window   externalGLControl true, false false Let the external window control OpenGL i.e. don't select a pixel format for the window, do not change v-sync and do not swap buffer. When set to true, the calling application is responsible of OpenGL initialization and buffer swapping. It should also create an OpenGL context for its own rendering, Ogre will create one for its use. Then the calling application must also enable Ogre OpenGL context before calling any Ogre function and restore its OpenGL context after these calls. OpenGL specific externalGLContext Context as Unsigned Long 0 (create own context) Use an externally created GL context OpenGL Specific parentWindowHandle Win32: HWND as integer GLX: poslong:posint:poslong (display*:screen:windowHandle) or poslong:posint:poslong:poslong (display*:screen:windowHandle:XVisualInfo*) 0 (none) Parent window handle, for embedding the OGRE in a child of an external window   contentScalingFactor Positive Float greater than 1.0 The default content scaling factor of the screen Specifies the CAEAGLLayer content scaling factor. Only supported on iOS 4 or greater. This can be useful to limit the resolution of the OpenGL ES backing store. For example, the iPhone 4's native resolution is 960 x 640.

Viewport& Ogre::RenderSystem::_getCurrentRenderViewport ( )

inline

_getDefaultViewportMaterialScheme()

_setPointParameters()

virtual void Ogre::RenderSystem::_setPointParameters ( Real  size, bool  attenuationEnabled, Real  constant, Real  linear, Real  quadratic, Real  minSize, Real  maxSize  )

pure virtual

Sets the size of points and how they are attenuated with distance.

Remarks

When performing point rendering or point sprite rendering, point size can be attenuated with distance. The equation for doing this is attenuation = 1 / (constant + linear * dist + quadratic * d^2) .

For example, to disable distance attenuation (constant screensize) you would set constant to 1, and linear and quadratic to 0. A standard perspective attenuation would be 0, 1, 0 respectively.

virtual void Ogre::RenderSystem::_setSurfaceParams ( const ColourValue &  ambient, const ColourValue &  diffuse, const ColourValue &  specular, const ColourValue &  emissive, Real  shininess, TrackVertexColourType  tracking = TVC_NONE  )

pure virtual

Sets the surface properties to be used for future rendering.

This method sets the the properties of the surfaces of objects to be rendered after it. In this context these surface properties are the amount of each type of light the object reflects (determining it's colour under different types of light), whether it emits light itself, and how shiny it is. Textures are not dealt with here, see the _setTetxure method for details. This method is used by _setMaterial so does not need to be called direct if that method is being used.

Parameters

ambient	The amount of ambient (sourceless and directionless) light an object reflects. Affected by the colour/amount of ambient light in the scene.
diffuse	The amount of light from directed sources that is reflected (affected by colour/amount of point, directed and spot light sources)
specular	The amount of specular light reflected. This is also affected by directed light sources but represents the colour at the highlights of the object.
emissive	The colour of light emitted from the object. Note that this will make an object seem brighter and not dependent on lights in the scene, but it will not act as a light, so will not illuminate other objects. Use a light attached to the same SceneNode as the object for this purpose.
shininess	A value which only has an effect on specular highlights (so specular must be non-black). The higher this value, the smaller and crisper the specular highlights will be, imitating a more highly polished surface. This value is not constrained to 0.0-1.0, in fact it is likely to be more (10.0 gives a modest sheen to an object).
tracking	A bit field that describes which of the ambient, diffuse, specular and emissive colours follow the vertex colour of the primitive. When a bit in this field is set its ColourValue is ignored. This is a combination of TVC_AMBIENT, TVC_DIFFUSE, TVC_SPECULAR(note that the shininess value is still taken from shininess) and TVC_EMISSIVE. TVC_NONE means that there will be no material property tracking the vertex colours.

Implemented in Ogre::VulkanRenderSystem, Ogre::NULLRenderSystem, Ogre::MetalRenderSystem, Ogre::GL3PlusRenderSystem, Ogre::D3D11RenderSystem, and Ogre::GLES2RenderSystem.

enabled	Boolean to turn the unit on/off
texPtr	Pointer to the texture to use.

_setTextureBlendMode()

virtual void Ogre::RenderSystem::_setTextureBlendMode ( size_t  unit, const LayerBlendModeEx &  bm  )

_setTextureUnitSettings()

virtual void Ogre::RenderSystem::_setTextureUnitSettings ( size_t  texUnit, TextureUnitState &  tl  )

virtual

Utility function for setting all the properties of a texture unit at once.

This method is also worth using over the individual texture unit settings because it only sets those settings which are different from the current settings for this unit, thus minimising render state changes.

pure virtual

Part of the low level rendering interface.

Tells the RS which VAO will be bound now. (i.e. Vertex Formats, buffers being bound, etc.) You don't need to rebind if the VAO's mRenderQueueId is the same as previous call.

Remarks

Assumes _setPipelineStateObject has already been called.

Binds a texture to a vertex, geometry, compute, tessellation hull or tessellation domain sampler.

Remarks

Not all rendersystems support separate vertex samplers. For those that do, you can set a texture for them, separate to the regular texture samplers, using this method. For those that don't, you should use the regular texture samplers which are shared between the vertex and fragment units; calling this method will throw an exception.

addClipPlane() [2/2]

virtual void Ogre::RenderSystem::addClipPlane ( Real  A, Real  B, Real  C, Real  D  )

virtual

Add a user clipping plane.

addListener()

virtual void Ogre::RenderSystem::addListener ( Listener *  l )

virtual

Adds a listener to the custom events that this render system can raise.

Remarks

Some render systems have quite specific, internally generated events that the application may wish to be notified of. Many applications don't have to worry about these events, and can just trust OGRE to handle them, but if you want to know, you can add a listener here.

Events are raised very generically by string name. Perhaps the most common example of a render system specific event is the loss and restoration of a device in DirectX; which OGRE deals with, but you may wish to know when it happens.

See also

RenderSystem::getRenderSystemEvents

addSharedListener()

static void Ogre::RenderSystem::addSharedListener ( Listener *  listener )

static

Sets shared listener.

Remarks

Shared listener could be set even if no render system is selected yet. This listener will receive "RenderSystemChanged" event on each Root::setRenderSystem call.

beginRenderPassDescriptor()

virtual void Ogre::RenderSystem::beginRenderPassDescriptor ( RenderPassDescriptor *  desc, TextureGpu *  anyTarget, uint8  mipLevel, const Vector4 *  viewportSizes, const Vector4 *  scissors, uint32  numViewports, bool  overlaysEnabled, bool  warnIfRtvWasFlushed  )

virtual

When the descriptor is set to Load clear, two possible things may happen:

1. The region is cleared.
2. The whole texture is cleared. What actually happens is undefined (depends on the API). But calling "beginRenderPassDescriptor( desc, viewportSettings );" with the same descriptor but different viewports (without changing the desc) guarantees that each region is cleared:

1. Each time the subregion is switched
2. Only once (the whole texture), when the first viewport was set.

   When switching between render targets, two beginRenderPassDescriptor in a row automatically implies calls endRenderPassDescriptor. In fact this is faster to perfom than calling beginRenderPassDescriptor - endRenderPassDescriptor in pairs, because we can smartly flush only what needs to be flushed. endRenderPassDescriptor only needs to be called when no other beginRenderPassDescriptor will follow (i.e. at the end of the frame or when starting compute jobs)

   Parameters

   desc
   anyTarget	Contains the first valid texture in mRenderPassDesc, to be used for reference (e.g. width, height, etc). Could be colour, depth, stencil, or nullptr.
   mipLevel	Mip at which anyTarget is bound
   viewportSize
   warnIfRtvWasFlushed	See CompositorPassDef::mWarnIfRtvWasFlushed

Reimplemented in Ogre::VulkanRenderSystem, Ogre::MetalRenderSystem, Ogre::GL3PlusRenderSystem, and Ogre::D3D11RenderSystem.

checkExtension()

virtual bool Ogre::RenderSystem::checkExtension ( const String &  ext ) const

inlinevirtual

Reimplemented in Ogre::GLES2RenderSystem.

clearFrameBuffer()

virtual void Ogre::RenderSystem::clearFrameBuffer ( RenderPassDescriptor *  renderPassDesc, TextureGpu *  anyTarget, uint8  mipLevel  )

pure virtual

Immediately clears the whole frame buffer on the selected RenderPassDescriptor.

Prefer clearing using the LoadAction semantics in the RenderPassDescriptor. This function is provided for two reasons:

1. Backwards compatibility (i.e. easier porting from 2.1)
2. Non-tilers desktop GPUs may be faster to clear the whole framebuffer at once.

   Remarks

   Will break an existing RenderPassDescriptor set via beginRenderPassDescriptor.

   Parameters

   renderPassDesc

   RenderPassDescriptor filled with LoadActions set to clear and StoreActions set to Store.

Implemented in Ogre::VulkanRenderSystem, Ogre::NULLRenderSystem, Ogre::MetalRenderSystem, Ogre::GL3PlusRenderSystem, and Ogre::D3D11RenderSystem.

convertColourValue()

virtual void Ogre::RenderSystem::convertColourValue ( const ColourValue &  colour, uint32 *  pDest  )

virtual

Generates a packed data version of the passed in ColourValue suitable for use as with this RenderSystem.

)

destroyRenderWindow()

virtual void Ogre::RenderSystem::destroyRenderWindow ( Window *  window )

virtual

Destroys a render window.

endCopyEncoder()

virtual void Ogre::RenderSystem::endCopyEncoder ( )

inlinevirtual

Required when caller will soon start analyzing barriers (e.g.

use BarrierSolver) Ogre will flush any pending resource transitions.

Otherwise BarrierSolver will see that a Resource is in a particular state or layout, then when calling executeResourceTransition, the pending resource layout will be flushed, and now the resource transition resolved by BarrierSolver will have the wrong 'old' layout

Reimplemented in Ogre::VulkanRenderSystem.

endGpuDebuggerFrameCapture()

virtual void Ogre::RenderSystem::endGpuDebuggerFrameCapture ( Window *  window, const bool  bDiscard = false  )

virtual

endRenderPassDescriptor()

virtual void Ogre::RenderSystem::endRenderPassDescriptor ( )

virtual

Reimplemented in Ogre::VulkanRenderSystem, Ogre::MetalRenderSystem, Ogre::GL3PlusRenderSystem, and Ogre::D3D11RenderSystem.

executeRenderPassDescriptorDelayedActions()

virtual void Ogre::RenderSystem::executeRenderPassDescriptorDelayedActions ( )

virtual

Metal needs to delay RenderCommand creation to the last minute, because we can't issue blit operations (e.g.

buffer copies) which a lot of v1 code relies on otherwise the RenderCommand gets canceled. Even if we were to get rid of v1 operations, the user may want to hook listeners for _renderPhase02 and perform forbidden operations. Therefore it's easier to split the process done in beginRenderPassDescriptor in two steps (beginRenderPassDescriptor and executeRenderPassDescriptorDelayedActions) for Metal.

Reimplemented in Ogre::VulkanRenderSystem, and Ogre::MetalRenderSystem.

executeResourceTransition()

virtual void Ogre::RenderSystem::executeResourceTransition ( const ResourceTransitionArray &  rstCollection )

getConfigOptions()

virtual ConfigOptionMap& Ogre::RenderSystem::getConfigOptions ( )

pure virtual

Returns the details of this API's configuration options.

Remarks

Each render system must be able to inform the world of what options must/can be specified for it's operation.

These are passed as strings for portability, but grouped into a structure (_ConfigOption) which includes both options and current value.

Note that the settings returned from this call are affected by the options that have been set so far, since some options are interdependent.

This routine is called automatically by the default configuration dialogue produced by Root::showConfigDialog or may be used by the caller for custom settings dialogs

Returns

A 'map' of options, i.e. a list of options which is also indexed by option name.

Implemented in Ogre::VulkanRenderSystem, Ogre::NULLRenderSystem, Ogre::MetalRenderSystem, Ogre::GL3PlusRenderSystem, Ogre::D3D11RenderSystem, and Ogre::GLES2RenderSystem.

const

Gets the global number of instances.

getHorizontalTexelOffset()

virtual Real Ogre::RenderSystem::getHorizontalTexelOffset ( )

pure virtual

Returns the horizontal texel offset value required for mapping texel origins to pixel origins in this rendersystem.

Remarks

Since rendersystems sometimes disagree on the origin of a texel, mapping from texels to pixels can sometimes be problematic to implement generically. This method allows you to retrieve the offset required to map the origin of a texel to the origin of a pixel in the horizontal direction.

Implemented in Ogre::VulkanRenderSystem, Ogre::NULLRenderSystem, Ogre::MetalRenderSystem, Ogre::GL3PlusRenderSystem, Ogre::D3D11RenderSystem, and Ogre::GLES2RenderSystem.

getInvertedClipSpaceY()

getMaximumDepthInputValue()

virtual Real Ogre::RenderSystem::getMaximumDepthInputValue ( )

pure virtual

Gets the maximum (farthest) depth value to be used when rendering using identity transforms.

Remarks

When using identity transforms you can manually set the depth of a vertex; however the input values required differ per rendersystem. This method lets you retrieve the correct value.

See also

Renderable::getUseIdentityView, Renderable::getUseIdentityProjection

Implemented in Ogre::VulkanRenderSystem, Ogre::NULLRenderSystem, Ogre::MetalRenderSystem, Ogre::GL3PlusRenderSystem, Ogre::D3D11RenderSystem, and Ogre::GLES2RenderSystem.

getMetrics()

(

)

const

getMinimumDepthInputValue()

virtual Real Ogre::RenderSystem::getMinimumDepthInputValue ( )

pure virtual

Gets the minimum (closest) depth value to be used when rendering using identity transforms.

Remarks

When using identity transforms you can manually set the depth of a vertex; however the input values required differ per rendersystem. This method lets you retrieve the correct value.

getMutableCapabilities()

RenderSystemCapabilities* Ogre::RenderSystem::getMutableCapabilities ( )

inline

Get a pointer to the current capabilities being used by the RenderSystem.

Remarks

The capabilities may be modified using this pointer, this will only have an effect before the RenderSystem has been initialised. It's intended use is to allow a listener of the RenderSystemCapabilitiesCreated event to customise the capabilities on the fly before the RenderSystem is initialised.

getName()

virtual const String& Ogre::RenderSystem::getName ( ) const

pure virtual

Returns the name of the rendering system.

Implemented in Ogre::VulkanRenderSystem, Ogre::NULLRenderSystem, Ogre::MetalRenderSystem, Ogre::GL3PlusRenderSystem, Ogre::D3D11RenderSystem, and Ogre::GLES2RenderSystem.

uint16 Ogre::RenderSystem::getNativeShadingLanguageVersion ( ) const

inline

Gets the native shading language version for this render system.

Formatted so that it can be used within a shading program. For example, OpenGL 3.2 would return 150, while 3.3 would return 330

getNumPriorityConfigOptions()

virtual size_t Ogre::RenderSystem::getNumPriorityConfigOptions ( ) const

virtual

Number of priority config options in RenderSystem::getPriorityConfigOption.

Remarks

IMPORTANT: The return value can change after calls to setConfigOption, it can even return higher or lower values than before.

Therefore a proper loop would call getNumPriorityConfigOptions on every iteration:

// GOOD:
for( size_t i=0; i < rs->getNumPriorityConfigOptions(); ++i )
    rs->setConfigOption( rs->getPriorityConfigOption( i ), value );
 
// BAD:
const size_t cachedNumOptions = rs->getNumPriorityConfigOptions();
for( size_t i=0; i < cachedNumOptions; ++i )
    rs->setConfigOption( rs->getPriorityConfigOption( i ), value );

Reimplemented in Ogre::VulkanRenderSystem, Ogre::GL3PlusRenderSystem, and Ogre::D3D11RenderSystem.

getPriorityConfigOption()

virtual const char* Ogre::RenderSystem::getPriorityConfigOption ( size_t  idx ) const

virtual

Some options depend on other options.

Therefore it's best to call RenderSystem::setConfigOption in order

Parameters

idx	Value must be in range [0; getNumPriorityConfigOptions)

Options must be set in ascending order, i.e. idx = 0 must be called before idx = 1

Returns

The name to use in setConfigOption( name, value )

Reimplemented in Ogre::VulkanRenderSystem, Ogre::GL3PlusRenderSystem, and Ogre::D3D11RenderSystem.

getRenderDocApi()

RENDERDOC_API_1_4_1* Ogre::RenderSystem::getRenderDocApi ( )

inline

Returns the RenderDoc API handle in case you want to do more advanced functionality than what we expose.

Note we may return nullptr if RenderDoc was not yet loaded.

Call RenderSystem::loadRenderDocApi first if you wish the returned ptr to not be null (it may still be null if we fail to load RenderDoc)

getRenderSystemEvents()

virtual const StringVector& Ogre::RenderSystem::getRenderSystemEvents ( ) const

inlinevirtual

Gets a list of the rendersystem specific events that this rendersystem can raise.

See also

RenderSystem::addListener

getRSDepthRange()

virtual Real Ogre::RenderSystem::getRSDepthRange ( ) const

inlinevirtual

OpenGL depth is in range [-1;1] so it returns 2.0f; D3D11 & Metal are in range [0;1] so it returns 1.0f;.

Note OpenGL may behave like D3D11, and thus we'll return 1.0f too. This is decided at runtime, not at compile time.

Reimplemented in Ogre::GL3PlusRenderSystem.

getStencilBufferParams()

const StencilParams& Ogre::RenderSystem::getStencilBufferParams ( ) const

inline

getTextureGpuManager()

TextureGpuManager* Ogre::RenderSystem::getTextureGpuManager ( ) const

inline

getVerticalTexelOffset()

virtual Real Ogre::RenderSystem::getVerticalTexelOffset ( )

pure virtual

Returns the vertical texel offset value required for mapping texel origins to pixel origins in this rendersystem.

Remarks

Since rendersystems sometimes disagree on the origin of a texel, mapping from texels to pixels can sometimes be problematic to implement generically. This method allows you to retrieve the offset required to map the origin of a texel to the origin of a pixel in the vertical direction.

Implemented in Ogre::VulkanRenderSystem, Ogre::NULLRenderSystem, Ogre::MetalRenderSystem, Ogre::GL3PlusRenderSystem, Ogre::D3D11RenderSystem, and Ogre::GLES2RenderSystem.

bool Ogre::RenderSystem::isReverseDepth ( ) const

inline

isSameLayout()

virtual bool Ogre::RenderSystem::isSameLayout ( ResourceLayout::Layout  a, ResourceLayout::Layout  b, const TextureGpu *  texture, bool  bIsDebugCheck  ) const

virtual

Returns true if 'a' and 'b' internally map to the same layout and should be considered equivalent for a given texture.

Parameters

bIsDebugCheck

When true, we're calling this as a consistency check (e.g. asserts if layouts changed externally outside the BarrierSolver). Non-explicit APIs may return too many false negatives triggering the assert, thus this flag prevents false crashes

Reimplemented in Ogre::VulkanRenderSystem.

isStaticBufferLockable()

virtual bool Ogre::RenderSystem::isStaticBufferLockable ( ) const

inlinevirtual

loadPipelineCache()

virtual void Ogre::RenderSystem::loadPipelineCache ( DataStreamPtr  stream )

virtual

Loads the pipeline cache from disk.

Parameters

stream

The source stream, optional, starts with struct PipelineCachePrefixHeader

Reimplemented in Ogre::VulkanRenderSystem.

loadRenderDocApi()

bool Ogre::RenderSystem::loadRenderDocApi

(

)

Explicitly loads RenderDoc.

It is not necessary to call this function unless you want to use RenderSystem::getRenderDocApi before we are required to load RenderDoc.

markProfileEvent()

virtual void Ogre::RenderSystem::markProfileEvent ( const String &  event )

pure virtual

Marks an instantaneous event for graphics profilers.

This is equivalent to calling beginProfileEvent() and endProfileEvent() back to back.

Implemented in Ogre::GL3PlusRenderSystem, Ogre::D3D11RenderSystem, Ogre::GLES2RenderSystem, Ogre::VulkanRenderSystem, Ogre::NULLRenderSystem, and Ogre::MetalRenderSystem.

postExtraThreadsStarted()

virtual void Ogre::RenderSystem::postExtraThreadsStarted ( )

pure virtual

Implemented in Ogre::VulkanRenderSystem, Ogre::NULLRenderSystem, Ogre::MetalRenderSystem, Ogre::GL3PlusRenderSystem, Ogre::D3D11RenderSystem, and Ogre::GLES2RenderSystem.

preExtraThreadsStarted()

virtual void Ogre::RenderSystem::preExtraThreadsStarted ( )

pure virtual

Tell the rendersystem to perform any prep tasks it needs to directly before other threads which might access the rendering API are registered.

Remarks

Call this from your main thread before starting your other threads (which themselves should call registerThread()). Note that if you start your own threads, there is a specific startup sequence which must be respected and requires synchronisation between the threads:

1. [Main thread]Call preExtraThreadsStarted
2. [Main thread]Start other thread, wait
3. [Other thread]Call registerThread, notify main thread & continue
4. [Main thread]Wake up & call postExtraThreadsStarted

Once this init sequence is completed the threads are independent but this startup sequence must be respected.

Implemented in Ogre::VulkanRenderSystem, Ogre::NULLRenderSystem, Ogre::MetalRenderSystem, Ogre::GL3PlusRenderSystem, Ogre::D3D11RenderSystem, and Ogre::GLES2RenderSystem.

queueBindUAVs()

void Ogre::RenderSystem::queueBindUAVs

(

const DescriptorSetUav *

descSetUav

)

Queues the binding of an UAV to the binding point/slot.

It won't actually take effect until you flush the UAVs or set another RTT.

Remarks

Internal Developer Notes: D3D11 keeps UAVs that affect rendering separate from UAVs that affect Compute Shaders. Hence queueBindUAVs & _setTextureCS are independent.

OpenGL however, does not make this distinction. Hence once we switch back to 3D rendering, we need to restore UAVs set via queueBindUAV.

registerThread()

virtual void Ogre::RenderSystem::registerThread ( )

pure virtual

Register the an additional thread which may make calls to rendersystem-related objects.

Remarks

This method should only be called by additional threads during their initialisation. If they intend to use hardware rendering system resources they should call this method before doing anything related to the render system. Some rendering APIs require a per-thread setup and this method will sort that out. It is also necessary to call unregisterThread before the thread shuts down.

Note

This method takes no parameters - it must be called from the thread being registered and that context is enough.

Implemented in Ogre::VulkanRenderSystem, Ogre::NULLRenderSystem, Ogre::MetalRenderSystem, Ogre::GL3PlusRenderSystem, Ogre::D3D11RenderSystem, and Ogre::GLES2RenderSystem.

reinitialise()

virtual void Ogre::RenderSystem::reinitialise ( )

virtual

Sets the user clipping region.

setConfigOption()

virtual void Ogre::RenderSystem::setConfigOption ( const String &  name, const String &  value  )

pure virtual

Sets an option for this API.

Remarks

Used to confirm the settings (normally chosen by the user) in order to make the renderer able to initialise with the settings as required. This may be video mode, D3D driver, full screen / windowed etc. Called automatically by the default configuration dialog, and by the restoration of saved settings. These settings are stored and only activated when RenderSystem::initialise or RenderSystem::reinitialise are called.

If using a custom configuration dialog, it is advised that the caller calls RenderSystem::getConfigOptions again, since some options can alter resulting from a selection.

Parameters

name	The name of the option to alter.
value	The value to set the option to.

Implemented in Ogre::VulkanRenderSystem, Ogre::NULLRenderSystem, Ogre::MetalRenderSystem, Ogre::GL3PlusRenderSystem, Ogre::D3D11RenderSystem, and Ogre::GLES2RenderSystem.

setCurrentPassIterationCount()

virtual void Ogre::RenderSystem::setCurrentPassIterationCount ( const size_t  count )

inlinevirtual

set the current multi pass count value.

This must be set prior to calling _render() if multiple renderings of the same pass state are required.

Parameters

count

Number of times to render the current state.

setDebugShaders()

void Ogre::RenderSystem::setDebugShaders

(

bool

bDebugShaders

)

Instructs the RenderSystem to compile shaders without optimizations and with debug information, for easier debugging on APIs that support it.

Default is true if OGRE_DEBUG_MODE >= OGRE_DEBUG_HIGH, else false

This setting takes effect for shaders compiled afterwards. Already compiled shaders won't change unless you manually rebuild them.

It is highly recommended you disable the Microcode cache before changing the default, or else debug shaders may contaminate your cache, or alternatively a shader from the cache may be used which may have been compiled with a different setting.

setDeriveDepthBias()

virtual void Ogre::RenderSystem::setDeriveDepthBias ( bool  derive, float  baseValue = 0.0f, float  multiplier = 0.0f, float  slopeScale = 0.0f  )

inlinevirtual

Tell the render system whether to derive a depth bias on its own based on the values passed to it in setCurrentPassIterationCount.

The depth bias set will be baseValue + iteration * multiplier

Parameters

derive	True to tell the RS to derive this automatically
baseValue	The base value to which the multiplier should be added
multiplier	The amount of depth bias to apply per iteration
slopeScale	The constant slope scale bias for completeness

setDrawBuffer()

virtual bool Ogre::RenderSystem::setDrawBuffer ( ColourBufferType  colourBuffer )

inlinevirtual

Sets the colour buffer that the render system will to draw.

If the render system implementation or configuration does not support a particular value, then false will be returned and the current colour buffer value will not be modified.

Parameters

colourBuffer

Specifies the colour buffer that will be drawn into.

Reimplemented in Ogre::D3D11RenderSystem.

setGlobalInstanceVertexBuffer()

void Ogre::RenderSystem::setGlobalInstanceVertexBuffer

(

const v1::HardwareVertexBufferSharedPtr &

val

)

Sets the global instance vertex buffer.

setGlobalInstanceVertexBufferVertexDeclaration()

void Ogre::RenderSystem::setGlobalInstanceVertexBufferVertexDeclaration

(

v1::VertexDeclaration *

val

)

Sets vertex declaration for the global vertex buffer for the global instancing.

setGlobalNumberOfInstances()

void Ogre::RenderSystem::setGlobalNumberOfInstances

(

const size_t

val

)

Sets the global number of instances.

setInvertVertexWinding()

void Ogre::RenderSystem::setInvertVertexWinding

(

bool

invert

)

Sets whether or not vertex windings set should be inverted; this can be important for rendering reflections.

setMetricsRecordingEnabled()

void Ogre::RenderSystem::setMetricsRecordingEnabled

(

bool

bEnable

)

setStencilBufferParams()

virtual void Ogre::RenderSystem::setStencilBufferParams ( uint32  refValue, const StencilParams &  stencilParams  )

virtual

This method allows you to set all the stencil buffer parameters in one call.

Remarks

The stencil buffer is used to mask out pixels in the render target, allowing you to do effects like mirrors, cut-outs, stencil shadows and more. Each of your batches of rendering is likely to ignore the stencil buffer, update it with new values, or apply it to mask the output of the render. The stencil test is:

(Reference Value & Mask) CompareFunction (Stencil Buffer Value & Mask)

The result of this will cause one of 3 actions depending on whether the test fails, succeeds but with the depth buffer check still failing, or succeeds with the depth buffer check passing too.

Unlike other render states, stencilling is left for the application to turn on and off when it requires. This is because you are likely to want to change parameters between batches of arbitrary objects and control the ordering yourself. In order to batch things this way, you'll want to use OGRE's separate render queue groups (see RenderQueue) and register a RenderQueueListener to get notifications between batches.

Parameters

refValue	The reference value used in the comparison (dynamic)
stencilParams	The static parameters that involve more expensive state changes. Ogre dev implementors note: Should check if the stencilParams are different from before

Reimplemented in Ogre::VulkanRenderSystem, Ogre::MetalRenderSystem, Ogre::GL3PlusRenderSystem, Ogre::D3D11RenderSystem, and Ogre::GLES2RenderSystem.

setUavStartingSlot()

void Ogre::RenderSystem::setUavStartingSlot

(

uint32

startingSlot

)

In Direct3D11, UAV & RenderTargets share the same slots.

Because of this, we enforce the same behavior on all RenderSystems. An unfortunate consequence is that if you attach an MRT consisting of 3 RTs; the UAV needs to set at slot 3; not slot 0. This setting lets you tell Ogre the starting slot; so queueBindUAVs( descSet ) goes from slot 3 onwards if you call setUavStartingSlot( 3 )

Ogre will raise an exception in D3D11 if the starting slot is lower than the number of attached RTs, but will let it pass if you're using GL3+ [TODO: Make this behavior consistent?]

Remarks

Will not take effect until the next call to flushUAVs or setting a new RTT.

Parameters

startingSlot

Default value: 1.

setWBufferEnabled()

void Ogre::RenderSystem::setWBufferEnabled

(

bool

enabled

)

Sets whether or not W-buffers are enabled if they are available for this renderer.

Parameters

enabled

If true and the renderer supports them W-buffers will be used. If false W-buffers will not be used even if available. W-buffers are enabled by default for 16bit depth buffers and disabled for all other depths.

shutdown()

virtual void Ogre::RenderSystem::shutdown ( )

virtual

Shutdown the renderer and cleanup resources.

Reimplemented in Ogre::VulkanRenderSystem, Ogre::NULLRenderSystem, Ogre::MetalRenderSystem, Ogre::GL3PlusRenderSystem, Ogre::D3D11RenderSystem, and Ogre::GLES2RenderSystem.

startGpuDebuggerFrameCapture()

virtual bool Ogre::RenderSystem::startGpuDebuggerFrameCapture ( Window *  window )

virtual

Programmatically performs a GPU capture when attached to a GPU debugger like RenderDoc or Metal Graphics Debugger.

You must call RenderSystem::endGpuDebuggerFrameCapture

Remarks

Very big captures (e.g. lots of API calls between start/endGpuDebuggerFrameCapture) may result in the system running out of memory.

Parameters

window

Can be NULL for automatic capture.

See pRENDERDOC_StartFrameCapture's documentation

Returns

False if we know for certain we failed to capture (e.g. RenderDoc is not running, we were build without integration support, etc)

True if we believe the frame capture started. Note a capture may still fail regardless due to other more technical reasons, as rendering APIs are complex.

supportsMultithreadedShaderCompilation()

virtual bool Ogre::RenderSystem::supportsMultithreadedShaderCompilation ( ) const

virtual

Returns true if RenderSystem supports multithreaded shader and PSO compilation.

Support depends on the API, our implementation, and CMake setting OGRE_SHADER_COMPILATION_THREADING_MODE with which OgreNext was built.

Reimplemented in Ogre::VulkanRenderSystem, and Ogre::MetalRenderSystem.

unregisterThread()

virtual void Ogre::RenderSystem::unregisterThread ( )

pure virtual

Unregister an additional thread which may make calls to rendersystem-related objects.

RenderSystem::registerThread

Implemented in Ogre::VulkanRenderSystem, Ogre::NULLRenderSystem, Ogre::MetalRenderSystem, Ogre::GL3PlusRenderSystem, Ogre::D3D11RenderSystem, and Ogre::GLES2RenderSystem.

updateCompositorManager()

virtual void Ogre::RenderSystem::updateCompositorManager ( CompositorManager2 *  compositorManager )

virtual

This gives the renderer a chance to perform the compositor update in a special way.

When the render system is ready to perform the actual update it should just compositorManager->_updateImplementation.

Reimplemented in Ogre::MetalRenderSystem.

useCustomRenderSystemCapabilities()

virtual void Ogre::RenderSystem::useCustomRenderSystemCapabilities ( RenderSystemCapabilities *  capabilities )

virtual

Force the render system to use the special capabilities.

Can only be called before the render system has been fully initializer (before createWindow is called)

Parameters

capabilities

has to be a subset of the real capabilities and the caller is responsible for deallocating capabilities.

validateConfigOptions()

virtual String Ogre::RenderSystem::validateConfigOptions ( )

pure virtual

Validates the options set for the rendering system, returning a message if there are problems.

Note

If the returned string is empty, there are no problems.

Implemented in Ogre::VulkanRenderSystem, Ogre::NULLRenderSystem, Ogre::MetalRenderSystem, Ogre::GL3PlusRenderSystem, Ogre::D3D11RenderSystem, and Ogre::GLES2RenderSystem.

validateDevice()

virtual bool Ogre::RenderSystem::validateDevice ( bool  forceDeviceElection = false )

inlinevirtual

Some render systems have moments when GPU device is temporarily unavailable, for example when D3D11 device is lost, or when iOS app is in background, etc.

Reimplemented in Ogre::VulkanRenderSystem, and Ogre::D3D11RenderSystem.

validateSampleDescription()

virtual SampleDescription Ogre::RenderSystem::validateSampleDescription ( const SampleDescription &  sampleDesc, PixelFormatGpu  format, uint32  textureFlags  )

virtual

Returns supported sample description for requested FSAA mode, with graceful downgrading.

Note

Depth/Stencil-only buffer formats combined with TextureFlags::Uav is valid but a rarely-supported combination. Don't ask for it unless that's truly what you want.

Parameters

sampleDesc	Reqiested sample description.
format	Use PF_NULL returns to query support for framebuffer-less rendering.
textureFlags	See TextureFlags::TextureFlags. Relevant flags are: NotTexture RenderToTexture Uav RenderWindowSpecific

Returns

Supported sample description for requested FSAA mode, with graceful downgrading.
