Member Function Documentation

GLuint Ogre::GLFBOManager::_tryFormat (  GLenum  depthFormat, GLenum  stencilFormat )  [private]

bool Ogre::GLFBOManager::_tryPackedFormat (  GLenum  packedFormat  )  [private]

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. Implements Ogre::GLRTTManager.

bool Ogre::GLFBOManager::checkFormat (  PixelFormat  format  )  [virtual]

Check if a certain format is usable as FBO rendertarget format. Implements Ogre::GLRTTManager. Definition at line 101 of file OgreGLFBORenderTexture.h. References mProps, and Ogre::GLFBOManager::FormatProperties::valid.

GLFrameBufferObject* Ogre::GLFBOManager::createFrameBufferObject (   )

Create a framebuffer object.

virtual MultiRenderTarget* Ogre::GLFBOManager::createMultiRenderTarget (  const String &  name  )  [virtual]

Create a multi render target. Reimplemented from Ogre::GLRTTManager.

virtual GLFBORenderTexture* Ogre::GLFBOManager::createRenderTexture (  const String &  name, const GLSurfaceDesc &  target )  [virtual]

Create a texture rendertarget object. Implements Ogre::GLRTTManager.

void Ogre::GLFBOManager::destroyFrameBufferObject (  GLFrameBufferObject *   )

Destroy a framebuffer object.

void Ogre::GLFBOManager::detectFBOFormats (   )  [private]

Detect allowed FBO formats.

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

Get best depth and stencil supported for given internalFormat.
