Member Function Documentation

_reload()

void Ogre::GLES2FBOManager::_reload

(

)

Detects all supported fbo's and recreates the tempory fbo.

bind()

void Ogre::GLES2FBOManager::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::GLES2RTTManager.

checkFormat()

bool Ogre::GLES2FBOManager::checkFormat ( PixelFormat  format )

inlinevirtual

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

Implements Ogre::GLES2RTTManager.

createMultiRenderTarget()

virtual MultiRenderTarget* Ogre::GLES2FBOManager::createMultiRenderTarget ( const String &  name )

virtual

Create a multi render target.

Reimplemented from Ogre::GLES2RTTManager.

createRenderTexture()

virtual GLES2FBORenderTexture* Ogre::GLES2FBOManager::createRenderTexture ( const String &  name, const GLES2SurfaceDesc &  target, bool  writeGamma, uint  fsaa  )

virtual

Create a texture rendertarget object.

Implements Ogre::GLES2RTTManager.

getBestDepthStencil() [1/2]

virtual void Ogre::GLES2RTTManager::getBestDepthStencil ( GLenum  internalFormat, GLenum *  depthFormat, GLenum *  stencilFormat  )

inlinevirtualinherited

getBestDepthStencil() [2/2]

virtual void Ogre::GLES2FBOManager::getBestDepthStencil ( PixelFormat  depthFormat, PixelFormat  fboFormat, GLenum *  outDepthFormat, GLenum *  outStencilFormat  )

virtual

Get best depth and stencil supported for given internalFormat.

getSingleton()

static GLES2RTTManager & Ogre::Singleton< GLES2RTTManager >::getSingleton ( )

inlinestaticinherited

getSingletonPtr()

static GLES2RTTManager * Ogre::Singleton< GLES2RTTManager >::getSingletonPtr ( )

inlinestaticinherited

getSupportedAlternative()

virtual PixelFormat Ogre::GLES2RTTManager::getSupportedAlternative ( PixelFormat  format )

virtualinherited

Get the closest supported alternative format.

If format is supported, returns format.

getTemporaryFBO()

GLuint Ogre::GLES2FBOManager::getTemporaryFBO

(

size_t

i

)

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

releaseRenderBuffer()

void Ogre::GLES2FBOManager::releaseRenderBuffer

(

const GLES2SurfaceDesc &

surface

)

Release a render buffer.

Ignore silently if surface.buffer is 0.

requestRenderBuffer() [1/2]

void Ogre::GLES2FBOManager::requestRenderBuffer

(

const GLES2SurfaceDesc &

surface

)

Request the specify render buffer in case shared somewhere.

Ignore silently if surface.buffer is 0.

requestRenderBuffer() [2/2]

GLES2SurfaceDesc Ogre::GLES2FBOManager::requestRenderBuffer	(	GLenum	format,
		uint32	width,
		uint32	height,
		uint	fsaa
	)

Request a render buffer.

If format is GL_NONE, return a zero buffer.

unbind()

void Ogre::GLES2FBOManager::unbind ( RenderTarget *  target )

inlinevirtual

Unbind a certain render target.

No-op for FBOs.

Implements Ogre::GLES2RTTManager.
