_applyObliqueDepthProjection()

virtual void Ogre::NULLRenderSystem::_applyObliqueDepthProjection ( Matrix4 &  matrix, const Plane &  plane, bool  forGpuProgram  )

inlinevirtual

Update a perspective projection matrix to use 'oblique depth projection'.

Remarks

This method can be used to change the nature of a perspective transform in order to make the near plane not perpendicular to the camera view direction, but to be at some different orientation. This can be useful for performing arbitrary clipping (e.g. to a reflection plane) which could otherwise only be done using user clip planes, which are more expensive, and not necessarily supported on all cards.

Parameters

matrix	The existing projection matrix. Note that this must be a perspective transform (not orthographic), and must not have already been altered by this method. The matrix will be altered in-place.
plane	The plane which is to be used as the clipping plane. This plane must be in CAMERA (view) space.
forGpuProgram	Is this for use with a Gpu program or fixed-function

Implements Ogre::RenderSystem.

_beginFrame()

virtual void Ogre::NULLRenderSystem::_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::RenderSystem::_beginFrameOnce ( void  )

virtualinherited

Signifies the beginning of the main frame.

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

Reimplemented in Ogre::MetalRenderSystem.

_beginGeometryCount()

virtual void Ogre::RenderSystem::_beginGeometryCount ( void  )

virtualinherited

The RenderSystem will keep a count of tris rendered, this resets the count.

_bindTextureUavCS()

virtual void Ogre::NULLRenderSystem::_bindTextureUavCS ( uint32  slot, Texture *  texture, ResourceAccess::ResourceAccess  access, int32  mipmapLevel, int32  textureArrayIndex, PixelFormat  pixelFormat  )

virtual

Binds an UAV texture to a Compute Shader.

Remarks

See also

queueBindUAV param description.

Internal Developer Notes: D3D11 keeps UAVs that affect rendering separate from UAVs that affect Compute Shaders. Hence queueBindUAV & _bindTextureUavCS 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.

Implements Ogre::RenderSystem.

_cleanupDepthBuffers()

void Ogre::RenderSystem::_cleanupDepthBuffers ( bool  bCleanManualBuffers = true )

inherited

Removes all depth buffers.

Should be called on device lost and shutdown

Remarks

Advanced users can call this directly with bCleanManualBuffers=false to remove all depth buffers created for RTTs; when they think the pool has grown too big or they've used lots of depth buffers they don't need anymore, freeing GPU RAM.

_convertProjectionMatrix()

virtual void Ogre::NULLRenderSystem::_convertProjectionMatrix ( const Matrix4 &  matrix, Matrix4 &  dest, bool  forGpuProgram = false  )

inlinevirtual

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.

Implements Ogre::RenderSystem.

_createDepthBufferFor()

virtual DepthBuffer * Ogre::NULLRenderSystem::_createDepthBufferFor ( RenderTarget *  renderTarget, bool  exactMatchFormat  )

virtual

Creates a DepthBuffer that can be attached to the specified RenderTarget.

Remarks

It doesn't attach anything, it just returns a pointer to a new DepthBuffer Caller is responsible for putting this buffer into the right pool, for attaching, and deleting it. Here's where API-specific magic happens. Don't call this directly unless you know what you're doing.

Implements Ogre::RenderSystem.

_createRenderWindow()

virtual RenderWindow * Ogre::NULLRenderSystem::_createRenderWindow ( const String &  name, unsigned int  width, unsigned int  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

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.

virtual

Start up the renderer using the settings selected (Or the defaults if none have been selected).

Implements Ogre::RenderSystem.

_notifyCompositorNodeSwitchedRenderTarget()

virtual void Ogre::RenderSystem::_notifyCompositorNodeSwitchedRenderTarget ( RenderTarget *  previousTarget )

inlinevirtualinherited

This function was created because of Metal.

The Metal API doesn't have a 'device->clear( texture )' function. Instead we must specify we want to start rendering to a cleared surface. This allows mobile TBDR GPUs to begin rendering without having to load any data from memory (saves a lot of bandwidth and battery).

But it also means Ogre must do an effort to delay the clear operation as much as possible (until actual rendering to it, or until the texture is used for reading/sampling).

Normally, we'd want to stop deferring a clear and immediately issue it when _setRenderTarget gets called with a different pointer. However, the following scenario is too common: target rtt { pass clear {} pass render_scene { shadows myShadowNode } }

Ogre will first issue a clear, then begin executing the shadow node (which switches to the shadow map) then switch back to the original rtt to resume regular rendinering. In this common case we want to delay the clear, but _setRenderTarget is clearly not an trusted indication (we would get many false positives).

Therefore the compositor has much better knowledge, and it informs of this fact via this call.

Remarks

TODO: This function will eventually be removed. The Compositor should be creating a resource transition. We only need to force clear when we're going to be using the target as a texture for reading/sampling. That's exactly what ResourceTransitions are for.

Parameters

previousRenderTarget

RenderTarget that was being used (and we should clear if we have to).

Reimplemented in Ogre::MetalRenderSystem.

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

virtual

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.

Implements Ogre::RenderSystem.

_setSurfaceParams()

virtual void Ogre::NULLRenderSystem::_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

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.

Implements Ogre::RenderSystem.

_setTextureBlendMode()

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

Implements Ogre::RenderSystem.

_setTextureCoordSet()

virtual void Ogre::NULLRenderSystem::_setTextureCoordSet ( size_t  unit, size_t  index  )

Implements Ogre::RenderSystem.

_setTextureProjectionRelativeTo()

virtual void Ogre::RenderSystem::_setTextureProjectionRelativeTo ( bool  enabled, const Vector3 &  pos  )

virtualinherited

_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.

_setVertexArrayObject()

virtual void Ogre::NULLRenderSystem::_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, const TexturePtr &  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.

getHorizontalTexelOffset()

virtual Real Ogre::NULLRenderSystem::getHorizontalTexelOffset ( void  )

virtual

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

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.

getVerticalTexelOffset()

virtual Real Ogre::NULLRenderSystem::getVerticalTexelOffset ( void  )

virtual

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

postExtraThreadsStarted()

virtual void Ogre::NULLRenderSystem::postExtraThreadsStarted ( )

virtual

Implements Ogre::RenderSystem.

preExtraThreadsStarted()

virtual void Ogre::NULLRenderSystem::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.

queueBindUAV() [1/2]

virtual void Ogre::NULLRenderSystem::queueBindUAV ( uint32  slot, TexturePtr  texture, ResourceAccess::ResourceAccess  access = ResourceAccess::ReadWrite, int32  mipmapLevel = 0, int32  textureArrayIndex = 0, PixelFormat  pixelFormat = PF_UNKNOWN  )

virtual

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.

Parameters

bindPoint	The buffer binding location for shader access. For OpenGL this must be unique and is not related to the texture binding point.
access	The texture access privileges given to the shader.
mipmapLevel	The texture mipmap level to use.
textureArrayIndex	The index of the texture array to use. If texture is not a texture array, set to 0.
format	Texture format to be read in by shader. This may be different than the bound texture format. Will be the same is left as PF_UNKNOWN

Implements Ogre::RenderSystem.

queueBindUAV() [2/2]

virtual void Ogre::NULLRenderSystem::queueBindUAV ( uint32  slot, UavBufferPacked *  buffer, ResourceAccess::ResourceAccess  access = ResourceAccess::ReadWrite, size_t  offset = 0, size_t  sizeBytes = 0  )

virtual

See other overload.

The slots are shared with the textures'

Parameters

offset	Offset to bind, in bytes
sizeBytes	Size to bind, in bytes. Use 0 to bind until the end of the buffer.

Implements Ogre::RenderSystem.

registerThread()

virtual void Ogre::NULLRenderSystem::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::NULLRenderSystem::reinitialise ( void  )

virtual

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

Implements Ogre::RenderSystem.

removeListener()

virtualinherited

Sets the user clipping region.

setClipPlanesImpl()

virtual void Ogre::NULLRenderSystem::setClipPlanesImpl ( const PlaneList &  clipPlanes )

virtual

Internal method used to set the underlying clip planes when needed.

Implements Ogre::RenderSystem.

setConfigOption()

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

inlinevirtual

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.

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

count

Number 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.

setDepthBufferFor()

virtual void Ogre::RenderSystem::setDepthBufferFor ( RenderTarget *  renderTarget, bool  exactMatch  )

virtualinherited

Retrieves an existing DepthBuffer or creates a new one suited for the given RenderTarget and sets it.

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

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 )

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

colourBuffer

Specifies the colour buffer that will be drawn into.

inherited

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

setSharedListener()

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

staticinherited

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.

setStencilBufferParams()

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

virtualinherited

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::D3D11RenderSystem, Ogre::GL3PlusRenderSystem, Ogre::GLES2RenderSystem, and Ogre::MetalRenderSystem.

setUavStartingSlot()

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

virtualinherited

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 queueBindUAV( 0, ... ) can goes to slot 3 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.

Reimplemented in Ogre::GL3PlusRenderSystem.

setWBufferEnabled()

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

inherited

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

Parameters

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

virtualinherited

Force the render system to use the special capabilities.
