Member Function Documentation

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

virtual

Bind a certain render target.

Implements Ogre::GLRTTManager.

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

virtual

Check if a certain format is usable as rendertexture format.

Implements Ogre::GLRTTManager.

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

virtualinherited

Create a multi render target.

Reimplemented in Ogre::GLFBOManager.

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

virtual

Create a texture rendertarget object.

Implements Ogre::GLRTTManager.

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

virtualinherited

Reimplemented in Ogre::GLFBOManager.

Definition at line 87 of file OgreGLRenderTexture.h.

References GL_NONE.

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

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

static GLRTTManager & Ogre::Singleton< GLRTTManager >::getSingleton ( void  )

staticinherited

Definition at line 90 of file OgreSingleton.h.

static GLRTTManager * Ogre::Singleton< GLRTTManager >::getSingletonPtr ( void  )

staticinherited

Definition at line 92 of file OgreSingleton.h.

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

virtualinherited

Get the closest supported alternative format.

If format is supported, returns format.

void Ogre::GLPBRTTManager::releasePBuffer

(

PixelComponentType

ctype

)

Release PBuffer for a certain pixel format.

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

Create PBuffer for a certain pixel format and size.

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.

Implements Ogre::GLRTTManager.
