Class OpenGLState

java.lang.Object
de.grogra.glsl.OpenGLState
public class OpenGLState extends Object
OpenGLState stores all relevant information about the used OpenGL Context. This includes active shaders, FBOs and the state of tests like the alpha test, the z-test. It also stores the state of culling and blending. This is done to prevent unnecessary state changes. This class also gives access to the used FBOs through an instance of the GLSLFBOManager class. It stores all data shared by the different classes of OpenGL (Proteus).
