CC3OpenGLES11StateTrackerViewport tracks the viewport GL state.
The originalValueHandling property is set to kCC3GLESStateOriginalValueReadOnceAndRestore, which will cause the state to be automatically read once, on the first invocation of the open method, and to be automatically restored on each invocation of the close method.
- (id) initWithParent: | (CC3OpenGLES11StateTracker *) | aTracker | |
forState: | (GLenum) | aName | |
andGLSetFunction: | (CC3SetGLViewportFunction *) | setGLFunc | |
Initializes this instance with the specified enumerated GL name, and to use the specified gl* function to set the state in the GL engine.
