Member Function Documentation

createRenderTexture()

virtual RenderTexture* Ogre::GLRTTManager::createRenderTexture ( const String &  name, const GLSurfaceDesc &  target, bool  writeGamma, uint  fsaa  )

pure virtual

Create a texture rendertarget object.

Implemented in Ogre::GLES2FBOManager, Ogre::GLFBOManager, Ogre::GL3PlusFBOManager, Ogre::GLPBRTTManager, and Ogre::GLCopyingRTTManager.

releaseRenderBuffer()

void Ogre::GLRTTManager::releaseRenderBuffer

(

const GLSurfaceDesc &

surface

)

Release a render buffer.

Ignore silently if surface.buffer is 0.

checkFormat()

bool Ogre::GLRTTManager::checkFormat ( PixelFormat  format )

inline

Check if a certain format is usable as FBO rendertarget format.

bind()

virtual void Ogre::GLRTTManager::bind ( RenderTarget *  target )

inlinevirtual

Bind a certain render target.

Note

only needed for FBO RTTs

Reimplemented in Ogre::GLES2FBOManager, Ogre::GLFBOManager, Ogre::GLPBRTTManager, and Ogre::GLCopyingRTTManager.

unbind()

virtual void Ogre::GLRTTManager::unbind ( RenderTarget *  target )

inlinevirtual

Unbind a certain render target.

This is called before binding another RenderTarget, and before the context is switched. It can be used to do a copy, or just be a noop if direct binding is used.

Note

only needed for Copying or PBuffer RTTs

Reimplemented in Ogre::GLFBOManager, Ogre::GLPBRTTManager, and Ogre::GLCopyingRTTManager.

getBestDepthStencil()

virtual void Ogre::GLRTTManager::getBestDepthStencil ( PixelFormat  internalFormat, uint32 *  depthFormat, uint32 *  stencilFormat  )

inlinevirtual

Reimplemented in Ogre::GLES2FBOManager.

getSupportedAlternative()

PixelFormat Ogre::GLRTTManager::getSupportedAlternative

(

PixelFormat

format

)

Get the closest supported alternative format.

If format is supported, returns format.

getSingleton()

static GLRTTManager& Ogre::GLRTTManager::getSingleton ( void  )

static

Get the singleton instance.

getSingletonPtr()

static GLRTTManager* Ogre::GLRTTManager::getSingletonPtr ( void  )

static

Get the singleton instance.

requestRenderBuffer()

GLSurfaceDesc Ogre::GLRTTManager::requestRenderBuffer	(	unsigned	format,
		uint32	width,
		uint32	height,
		uint	fsaa
	)

Request a render buffer.

If format is GL_NONE, return a zero buffer.

createNewRenderBuffer()

virtual GLSurfaceDesc Ogre::GLRTTManager::createNewRenderBuffer ( unsigned  format, uint32  width, uint32  height, uint  fsaa  )

inlinevirtual

Creates a new render buffer.

Caller takes ownership.

Reimplemented in Ogre::GLES2FBOManager, Ogre::GLFBOManager, and Ogre::GL3PlusFBOManager.
