Member Function Documentation

◆ _addMetrics()

void Ogre::RenderSystem::_addMetrics ( const RenderingMetrics newMetrics)
inherited

◆ _beginFrame()

virtual void Ogre::MetalRenderSystem::_beginFrame ( void  )
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.

Implements Ogre::RenderSystem.

◆ _beginFrameOnce()

virtual void Ogre::MetalRenderSystem::_beginFrameOnce ( void  )
virtual

Signifies the beginning of the main frame.

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

Reimplemented from Ogre::RenderSystem.

◆ _cleanupDepthBuffers()

void Ogre::RenderSystem::_cleanupDepthBuffers ( void  )
inherited

◆ _clearStateAndFlushCommandBuffer()

virtual void Ogre::RenderSystem::_clearStateAndFlushCommandBuffer ( void  )
virtualinherited

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 
)
virtualinherited

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 
)
virtualinherited

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::MetalRenderSystem::_createRenderWindow ( const String name,
uint32  width,
uint32  height,
bool  fullScreen,
const NameValuePairList miscParams = 0 
)
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
nameThe name of the window. Used in other methods later like setRenderTarget and getRenderTarget.
widthThe width of the new window.
heightThe height of the new window.
fullScreenSpecify true to make the window full screen without borders, title bar or menu bar.
miscParamsA 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.

Returns the default material scheme used by the render system.

Systems that use the RTSS to emulate a fixed function pipeline (e.g. OpenGL ES 2, GL3+, DX11) need to override this function to return the default material scheme of the RTSS ShaderGenerator.

virtual void Ogre::MetalRenderSystem::_setPointParameters ( Real  size,
bool  attenuationEnabled,
Real  constant,
Real  linear,
Real  quadratic,
Real  minSize,

)
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.

◆ _setSurfaceParams()

virtual void Ogre::MetalRenderSystem::_setSurfaceParams ( const ColourValue ambient,
const ColourValue diffuse,
const ColourValue specular,
const ColourValue emissive,
Real  shininess,
TrackVertexColourType  tracking = TVC_NONE 
)
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
ambientThe amount of ambient (sourceless and directionless) light an object reflects. Affected by the colour/amount of ambient light in the scene.
diffuseThe amount of light from directed sources that is reflected (affected by colour/amount of point, directed and spot light sources)
specularThe amount of specular light reflected. This is also affected by directed light sources but represents the colour at the highlights of the object.
emissiveThe 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.
shininessA 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).
trackingA 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.

◆ _setTextureUnitSettings()

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

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.

◆ _setUavCS()

Implements Ogre::RenderSystem.

◆ _setVertexArrayObject()

virtual void Ogre::MetalRenderSystem::_setVertexArrayObject ( const VertexArrayObject vao)
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.

Implements Ogre::RenderSystem.

◆ _setVertexTexture()

virtual void Ogre::RenderSystem::_setVertexTexture ( size_t  unit,
TextureGpu tex 
)
virtualinherited

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.

◆ addListener()

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

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.

virtual void Ogre::MetalRenderSystem::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
    anyTargetContains the first valid texture in mRenderPassDesc, to be used for reference (e.g. width, height, etc). Could be colour, depth, stencil, or nullptr.
    mipLevelMip at which anyTarget is bound

◆ clearFrameBuffer()

virtual void Ogre::MetalRenderSystem::clearFrameBuffer ( RenderPassDescriptor renderPassDesc,
TextureGpu anyTarget,
uint8  mipLevel 
)
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
    renderPassDescRenderPassDescriptor filled with LoadActions set to clear and StoreActions set to Store.

◆ convertColourValue()

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

virtualinherited

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

Remarks
Since different render systems have different colour data formats (eg RGBA for GL, ARGB for D3D) this method allows you to use 1 method for all.

◆ endCopyEncoder()

virtual void Ogre::RenderSystem::endCopyEncoder ( void  )
inlinevirtualinherited

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.

◆ executeRenderPassDescriptorDelayedActions() [1/2]

void Ogre::MetalRenderSystem::executeRenderPassDescriptorDelayedActions ( bool  officialCall)

◆ executeRenderPassDescriptorDelayedActions() [2/2]

virtual void Ogre::MetalRenderSystem::executeRenderPassDescriptorDelayedActions ( void  )
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 from Ogre::RenderSystem.

◆ getConfigOptions()

virtual ConfigOptionMap& Ogre::MetalRenderSystem::getConfigOptions ( void  )
inlinevirtual

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.

◆ getHorizontalTexelOffset()

virtual Real Ogre::MetalRenderSystem::getHorizontalTexelOffset ( void  )
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.

Implements Ogre::RenderSystem.

◆ getInvertedClipSpaceY()

bool Ogre::RenderSystem::getInvertedClipSpaceY ( void  ) const

◆ getMutableCapabilities()

RenderSystemCapabilities* Ogre::RenderSystem::getMutableCapabilities ( )
inlineinherited

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::MetalRenderSystem::getName ( void  ) const
virtual

Returns the name of the rendering system.

Implements Ogre::RenderSystem.

◆ getNativeShadingLanguageVersion()

uint16 Ogre::RenderSystem::getNativeShadingLanguageVersion ( ) const
inlineinherited

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 ( void  ) const
virtualinherited

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.

◆ getPixelFormatToShaderType()

virtual

Implements Ogre::RenderSystem.

◆ getPriorityConfigOption()

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

Some options depend on other options.

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

Parameters
idxValue 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 ( void  )
inlineinherited

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 ( void  ) const
inlinevirtualinherited

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

See also
RenderSystem::addListener

◆ getRSDepthRange()

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

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.

◆ getVerticalTexelOffset()

virtual Real Ogre::MetalRenderSystem::getVerticalTexelOffset ( void  )
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.

Implements Ogre::RenderSystem.

◆ getWBufferEnabled()

bool Ogre::RenderSystem::getWBufferEnabled ( void  ) const

inlineinherited

◆ isSameLayout()

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

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

Parameters
bIsDebugCheckWhen 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()

inlinevirtualinherited

Reimplemented in Ogre::D3D9RenderSystem.

◆ loadRenderDocApi()

◆ postExtraThreadsStarted()

virtual void Ogre::MetalRenderSystem::postExtraThreadsStarted ( )
virtual

Implements Ogre::RenderSystem.

◆ preExtraThreadsStarted()

virtual void Ogre::MetalRenderSystem::preExtraThreadsStarted ( )
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.

Implements Ogre::RenderSystem.

◆ queueBindUAVs()

void Ogre::RenderSystem::queueBindUAVs ( const DescriptorSetUav descSetUav)
inherited

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::MetalRenderSystem::registerThread ( )
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.

Implements Ogre::RenderSystem.

◆ reinitialise()

virtual void Ogre::MetalRenderSystem::reinitialise ( void  )
virtual

Restart the renderer (normally following a change in settings).

Implements Ogre::RenderSystem.

◆ removeListener()

Implements Ogre::RenderSystem.

◆ setConfigOption()

virtual void Ogre::MetalRenderSystem::setConfigOption ( const String name,
const String value 
)
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
nameThe name of the option to alter.
valueThe value to set the option to.

Implements Ogre::RenderSystem.

◆ setCurrentPassIterationCount()

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

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
countNumber of times to render the current state.

◆ setDebugShaders()

void Ogre::RenderSystem::setDebugShaders ( bool  bDebugShaders)
inherited

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 
)
inlinevirtualinherited

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
deriveTrue to tell the RS to derive this automatically
baseValueThe base value to which the multiplier should be added
multiplierThe amount of depth bias to apply per iteration
slopeScaleThe constant slope scale bias for completeness

◆ setDrawBuffer()

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

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
colourBufferSpecifies the colour buffer that will be drawn into.

Reimplemented in Ogre::D3D9RenderSystem, and Ogre::D3D11RenderSystem.

◆ setInvertVertexWinding()

void Ogre::RenderSystem::setInvertVertexWinding ( bool  invert)
inherited

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

◆ setMetricsRecordingEnabled()

void Ogre::RenderSystem::setMetricsRecordingEnabled ( bool  bEnable)
inherited

◆ setStencilBufferParams()

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

Reimplemented from Ogre::RenderSystem.

◆ setUavStartingSlot()

void Ogre::RenderSystem::setUavStartingSlot ( uint32  startingSlot)
inherited

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
startingSlotDefault value: 1.

◆ setWBufferEnabled()

void Ogre::RenderSystem::setWBufferEnabled ( bool  enabled)
inherited

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

Parameters
enabledIf 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::MetalRenderSystem::shutdown ( void  )
virtual

Shutdown the renderer and cleanup resources.

Reimplemented from Ogre::RenderSystem.

◆ startGpuDebuggerFrameCapture()

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

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
windowCan 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.

virtual

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

Reimplemented from Ogre::RenderSystem.

◆ useCustomRenderSystemCapabilities()

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

Force the render system to use the special capabilities.
