GLuint Ogre::GLES2FBOManager::_tryFormat ( GLenum  depthFormat,
GLenum  stencilFormat 
) [private]
bool Ogre::GLES2FBOManager::_tryPackedFormat ( GLenum  packedFormat) [private]
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.

bool Ogre::GLES2FBOManager::checkFormat ( PixelFormat  format) [virtual]

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

Implements Ogre::GLES2RTTManager.

Definition at line 102 of file OgreGLES2FBORenderTexture.h.

Create a multi render target.

Reimplemented from Ogre::GLES2RTTManager.

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

Create a texture rendertarget object.

Implements Ogre::GLES2RTTManager.

Detect allowed FBO formats.

void Ogre::GLES2FBOManager::getBestDepthStencil ( GLenum  internalFormat,
GLenum *  depthFormat,
GLenum *  stencilFormat 
) [virtual]

Get best depth and stencil supported for given internalFormat.

Reimplemented from Ogre::GLES2RTTManager.

static GLES2RTTManager & Ogre::Singleton< GLES2RTTManager >::getSingleton ( void  ) [static, inherited]

Definition at line 90 of file OgreSingleton.h.

static GLES2RTTManager * Ogre::Singleton< GLES2RTTManager >::getSingletonPtr ( void  ) [static, inherited]

Definition at line 92 of file OgreSingleton.h.

Get the closest supported alternative format.

If format is supported, returns format.

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

Definition at line 106 of file OgreGLES2FBORenderTexture.h.

Release a render buffer.

Ignore silently if surface.buffer is 0.

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

Request a render buffer.

If format is GL_NONE, return a zero buffer.

Request the specify render buffer in case shared somewhere.

Ignore silently if surface.buffer is 0.

void Ogre::GLES2FBOManager::unbind ( RenderTarget target) [virtual]

Unbind a certain render target.

No-op for FBOs.

Implements Ogre::GLES2RTTManager.
