◆ _applyObliqueDepthProjection()

void Ogre::GLES2RenderSystem::_applyObliqueDepthProjection ( Matrix4 matrix,
const Plane plane,
bool  forGpuProgram 
)
virtual

See RenderSystem.

Implements Ogre::RenderSystem.

◆ _beginFrame()

void Ogre::GLES2RenderSystem::_beginFrame ( void  )
virtual

See RenderSystem.

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::GLES2RenderSystem::_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()

void Ogre::GLES2RenderSystem::_convertProjectionMatrix ( const Matrix4 matrix,
Matrix4 dest,
bool  forGpuProgram = false 
)
virtual

See RenderSystem.

Implements Ogre::RenderSystem.

◆ _createDepthBufferFor()

DepthBuffer * Ogre::GLES2RenderSystem::_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()

RenderWindow * Ogre::GLES2RenderSystem::_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
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. Windows are always 320 x 480, if you would like to limit the display to 720 x 480, specify 1.5 as the scaling factor. iOS Specific  
externalViewHandle UIView pointer as an integer 0 External view handle, for rendering OGRE render in an existing view iOS Specific

◆ _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
previousRenderTargetRenderTarget that was being used (and we should clear if we have to).

◆ _setTextureUnitSettings()

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

◆ _setVertexArrayObject()

virtual void Ogre::GLES2RenderSystem::_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

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.

◆ postExtraThreadsStarted()

void Ogre::GLES2RenderSystem::postExtraThreadsStarted ( )
virtual

Implements Ogre::RenderSystem.

◆ preExtraThreadsStarted()

void Ogre::GLES2RenderSystem::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::GLES2RenderSystem::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
bindPointThe buffer binding location for shader access. For OpenGL this must be unique and is not related to the texture binding point.
accessThe texture access privileges given to the shader.
mipmapLevelThe texture mipmap level to use.
textureArrayIndexThe index of the texture array to use. If texture is not a texture array, set to 0.
formatTexture 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.

size_t  sizeBytes = 0 
)
virtual

See other overload.

The slots are shared with the textures'

Parameters
offsetOffset to bind, in bytes
sizeBytesSize to bind, in bytes. Use 0 to bind until the end of the buffer.

Implements Ogre::RenderSystem.

◆ registerThread()

void Ogre::GLES2RenderSystem::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.

◆ 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,

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.

◆ setStencilBufferParams()

virtual void Ogre::GLES2RenderSystem::setStencilBufferParams ( uint32  refValue,
const StencilParams stencilParams 
)
virtual

See RenderSystem.

Reimplemented from Ogre::RenderSystem.

◆ 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
startingSlotDefault 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.
