Member Function Documentation

◆ _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

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. 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
externalViewControllerHandle	UIViewController pointer as an integer	0	External view controller handle, for embedding OGRE in an existing view controller	iOS Specific
externalSharegroup	EAGLSharegroup pointer as an integer	0	External sharegroup, used to shared GL resources between contexts	iOS Specific
Full Screen	true, false	false	Specify whether to create the window in full screen mode	OS X Specific
FSAA	Positive integer (usually 0, 2, 4, 8, 16)	0	Full screen antialiasing factor
FSAAHint	Depends on RenderSystem and hardware. Currently supports: "Quality": on systems that have an option to prefer higher AA quality over speed, use it	Blank	Full screen antialiasing hint

◆ _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.

◆ _setTextureUnitSettings()

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

◆ _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: 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:

[Main thread]Call preExtraThreadsStarted
[Main thread]Start other thread, wait
[Other thread]Call registerThread, notify main thread & continue
[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

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::GLES2RenderSystem::queueBindUAV	(	uint32	slot,
		UavBufferPacked *	buffer,
		ResourceAccess::ResourceAccess	access = `ResourceAccess::ReadWrite`,

		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()

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.

◆ setCurrentPassIterationCount()

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

inlinevirtualinherited

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()

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.

		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

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.

◆ updateCompositorManager()

virtual void Ogre::RenderSystem::updateCompositorManager	(	CompositorManager2 *	compositorManager,
		SceneManagerEnumerator &	sceneManagers,
		HlmsManager *	hlmsManager
	)

virtualinherited

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 )

virtualinherited

Force the render system to use the special capabilities.
