Member Function Documentation

◆ bind()

void Ogre::GLFBOManager::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.

Reimplemented from Ogre::GLRTTManager.

◆ unbind()

void Ogre::GLFBOManager::unbind ( RenderTarget target)
inlinevirtual

Unbind a certain render target.

No-op for FBOs.

Reimplemented from Ogre::GLRTTManager.

◆ getBestDepthStencil() [1/2]

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

Get best depth and stencil supported for given internalFormat.

◆ createRenderTexture()

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

Create a texture rendertarget object.

Implements Ogre::GLRTTManager.

◆ requestRenderBuffer()

GLSurfaceDesc Ogre::GLFBOManager::requestRenderBuffer ( GLenum  format,
uint32  width,
uint32  height,
uint  fsaa 
)

Request a render buffer.

If format is GL_NONE, return a zero buffer.

◆ getTemporaryFBO()

GLuint Ogre::GLFBOManager::getTemporaryFBO ( )
inline

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

◆ releaseRenderBuffer()

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

Release a render buffer.

Ignore silently if surface.buffer is 0.

◆ checkFormat()

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

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

◆ getBestDepthStencil() [2/2]

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.
