Member Function Documentation

◆ createRenderTexture()

virtual RenderTexture* Ogre::GLRTTManager::createRenderTexture ( const String name,
const GLSurfaceDesc target,
bool  writeGamma,
uint  fsaa 
)
pure virtual

◆ releaseRenderBuffer()

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

Release a render buffer.

Ignore silently if surface.buffer is 0.

◆ checkFormat()

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

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

◆ bind()

virtual void Ogre::GLRTTManager::bind ( RenderTarget target)
inlinevirtual

Bind a certain render target.

Note
only needed for FBO RTTs

Reimplemented in Ogre::GLES2FBOManager, Ogre::GLFBOManager, Ogre::GLPBRTTManager, and Ogre::GLCopyingRTTManager.

◆ unbind()

virtual void Ogre::GLRTTManager::unbind ( RenderTarget target)
inlinevirtual

Unbind a certain render target.

This is called before binding another RenderTarget, and before the context is switched. It can be used to do a copy, or just be a noop if direct binding is used.

Note
only needed for Copying or PBuffer RTTs

Reimplemented in Ogre::GLFBOManager, Ogre::GLPBRTTManager, and Ogre::GLCopyingRTTManager.

◆ getBestDepthStencil()

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

Reimplemented in Ogre::GLES2FBOManager.

◆ getSupportedAlternative()

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

Get the closest supported alternative format.

If format is supported, returns format.

◆ getSingleton()

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

Get the singleton instance.

◆ getSingletonPtr()

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

Get the singleton instance.
