Member Function Documentation

bind()

void Ogre::GLFBOManager::bind ( RenderTarget *  target )

virtual

Bind a certain render target if it is a FBO.

If it is not a FBO, bind the main frame buffer.

Implements Ogre::GLRTTManager.

unbind()

void Ogre::GLFBOManager::unbind ( RenderTarget *  target )

inlinevirtual

Unbind a certain render target.

No-op for FBOs.

Implements Ogre::GLRTTManager.

getBestDepthStencil() [1/2]

void Ogre::GLFBOManager::getBestDepthStencil	(	PixelFormat	internalFormat,
		GLenum *	depthFormat,
		GLenum *	stencilFormat
	)

Get best depth and stencil supported for given internalFormat.

createRenderTexture()

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

virtual

Create a texture rendertarget object.

Implements Ogre::GLRTTManager.

createMultiRenderTarget()

virtual MultiRenderTarget* Ogre::GLFBOManager::createMultiRenderTarget ( const String &  name )

virtual

Create a multi render target.

Reimplemented from Ogre::GLRTTManager.

requestRenderBuffer()

GLSurfaceDesc Ogre::GLFBOManager::requestRenderBuffer	(	GLenum	format,
		uint32	width,
		uint32	height,
		uint	fsaa
	)

Request a render buffer.

If format is GL_NONE, return a zero buffer.

getTemporaryFBO()

GLuint Ogre::GLFBOManager::getTemporaryFBO ( )

inline

Get a FBO without depth/stencil for temporary use, like blitting between textures.

releaseRenderBuffer()

void Ogre::GLRTTManager::releaseRenderBuffer ( const GLSurfaceDesc &  surface )

inherited

Release a render buffer.

Ignore silently if surface.buffer is 0.

checkFormat()

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

inlineinherited

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

getBestDepthStencil() [2/2]

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

inlinevirtualinherited

Reimplemented in Ogre::GLES2FBOManager.

getSupportedAlternative()

PixelFormat Ogre::GLRTTManager::getSupportedAlternative ( PixelFormat  format )

inherited

Get the closest supported alternative format.

If format is supported, returns format.

getSingleton()

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

staticinherited

Get the singleton instance.

getSingletonPtr()

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

staticinherited

Get the singleton instance.
