Member Function Documentation

◆ bind()

void Ogre::GL3PlusFBOManager::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::GL3PlusRTTManager.

◆ checkFormat()

bool Ogre::GL3PlusFBOManager::checkFormat ( PixelFormat  format)
inlinevirtual

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

Implements Ogre::GL3PlusRTTManager.

◆ createMultiRenderTarget()

virtual MultiRenderTarget * Ogre::GL3PlusFBOManager::createMultiRenderTarget ( const String name)
virtual

Create a multi render target.

Reimplemented from Ogre::GL3PlusRTTManager.

◆ createRenderTexture()

virtual GL3PlusFBORenderTexture * Ogre::GL3PlusFBOManager::createRenderTexture ( const String name,
const GL3PlusSurfaceDesc target,
bool  writeGamma,
uint  fsaa 
)
virtual

Create a texture rendertarget object.

Implements Ogre::GL3PlusRTTManager.

◆ getBestDepthStencil() [1/2]

virtual void Ogre::GL3PlusRTTManager::getBestDepthStencil ( GLenum  internalFormat,
GLenum depthFormat,
GLenum stencilFormat 
)
inlinevirtualinherited

◆ getBestDepthStencil() [2/2]

virtual void Ogre::GL3PlusFBOManager::getBestDepthStencil ( PixelFormat  depthFormat,
PixelFormat  fboFormat,
GLenum outDepthFormat,
GLenum outStencilFormat 
)
virtual

Get best depth and stencil supported for given internalFormat.

◆ getSingleton()

static GL3PlusRTTManager & Ogre::Singleton< GL3PlusRTTManager >::getSingleton ( void  )
inlinestaticinherited

◆ getSingletonPtr()

static GL3PlusRTTManager * Ogre::Singleton< GL3PlusRTTManager >::getSingletonPtr ( void  )
inlinestaticinherited

◆ getSupportedAlternative()

virtual PixelFormat Ogre::GL3PlusRTTManager::getSupportedAlternative ( PixelFormat  format)
virtualinherited

Get the closest supported alternative format.

If format is supported, returns format.

◆ getTemporaryFBO()

GLuint Ogre::GL3PlusFBOManager::getTemporaryFBO ( size_t  i)

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

◆ releaseRenderBuffer()

void Ogre::GL3PlusFBOManager::releaseRenderBuffer ( const GL3PlusSurfaceDesc surface)

Release a render buffer.

Ignore silently if surface.buffer is 0.

◆ requestRenderBuffer() [1/2]

void Ogre::GL3PlusFBOManager::requestRenderBuffer ( const GL3PlusSurfaceDesc surface)

Request the specify render buffer in case shared somewhere.

Ignore silently if surface.buffer is 0.

◆ requestRenderBuffer() [2/2]

GL3PlusSurfaceDesc Ogre::GL3PlusFBOManager::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::GL3PlusFBOManager::unbind ( RenderTarget target)
inlinevirtual

Unbind a certain render target.

No-op for FBOs.

Implements Ogre::GL3PlusRTTManager.
