Class GLCapability

java.lang.Object
  hmi.graphics.opengl.state.GLCapability

All Implemented Interfaces:

GLRenderObject, GLStateComponent

public class GLCapability
extends Object
implements GLStateComponent

A GLCapability is a wrapper for some OpenGL capability. The capability will be enabled or disabled when the glInit() or glRender() method is called, depending on the current state of the GLCapability object.
