Member Function Documentation

◆ createRenderTexture()

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

Create a texture rendertarget object.

Implements Ogre::GLRTTManager.

◆ checkFormat()

virtual bool Ogre::GLPBRTTManager::checkFormat ( PixelFormat  format)
virtual

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

◆ bind()

virtual void Ogre::GLPBRTTManager::bind ( RenderTarget target)
virtual

Bind a certain render target.

Note
only needed for FBO RTTs

Reimplemented from Ogre::GLRTTManager.

◆ unbind()

virtual void Ogre::GLPBRTTManager::unbind ( RenderTarget target)
virtual

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 from Ogre::GLRTTManager.

◆ requestPBuffer()

void Ogre::GLPBRTTManager::requestPBuffer ( PixelComponentType  ctype,
uint32  width,
uint32  height 
)

Create PBuffer for a certain pixel format and size.

◆ releasePBuffer()

void Ogre::GLPBRTTManager::releasePBuffer ( PixelComponentType  ctype)

Release PBuffer for a certain pixel format.

◆ getContextFor()

GLContext* Ogre::GLPBRTTManager::getContextFor ( PixelComponentType  ctype,
uint32  width,
uint32  height 
)

Get GL rendering context for a certain component type and size.

◆ releaseRenderBuffer()

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

Release a render buffer.

Ignore silently if surface.buffer is 0.

◆ getBestDepthStencil()

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

Reimplemented in Ogre::GLES2FBOManager.

◆ getSupportedAlternative()

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

Get the closest supported alternative format.

If format is supported, returns format.

◆ getSingleton()

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

Get the singleton instance.

◆ getSingletonPtr()

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

Get the singleton instance.
