private

bool Ogre::GLESFBOManager::_tryPackedFormat ( GLenum  packedFormat )

private

void Ogre::GLESFBOManager::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::GLESRTTManager.

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

inlinevirtual

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

Implements Ogre::GLESRTTManager.

Definition at line 102 of file OgreGLESFBORenderTexture.h.

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

virtual

Create a multi render target.

Reimplemented from Ogre::GLESRTTManager.

virtual GLESFBORenderTexture* Ogre::GLESFBOManager::createRenderTexture ( const String &  name, const GLESSurfaceDesc &  target, bool  writeGamma, uint  fsaa  )

virtual

Create a texture rendertarget object.

Implements Ogre::GLESRTTManager.

void Ogre::GLESFBOManager::detectFBOFormats ( )

private

Detect allowed FBO formats.

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

virtual

Get best depth and stencil supported for given internalFormat.

Reimplemented from Ogre::GLESRTTManager.

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

virtualinherited

Get the closest supported alternative format.

If format is supported, returns format.

GLuint Ogre::GLESFBOManager::getTemporaryFBO ( )

inline

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

Definition at line 106 of file OgreGLESFBORenderTexture.h.

void Ogre::GLESFBOManager::releaseRenderBuffer

(

const GLESSurfaceDesc &

surface

)

Release a render buffer.

Ignore silently if surface.buffer is 0.

GLESSurfaceDesc Ogre::GLESFBOManager::requestRenderBuffer	(	GLenum	format,
		size_t	width,
		size_t	height,
		uint	fsaa
	)

Request a render buffer.

If format is GL_NONE, return a zero buffer.

void Ogre::GLESFBOManager::requestRenderBuffer

(

const GLESSurfaceDesc &

surface

)

Request the specify render buffer in case shared somewhere.

Ignore silently if surface.buffer is 0.

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

inlinevirtual

Unbind a certain render target.

No-op for FBOs.

Implements Ogre::GLESRTTManager.
