Class GLWorkerThread

java.lang.Object

com.sun.opengl.impl.GLWorkerThread

public class GLWorkerThread
extends java.lang.Object

Singleton thread upon which all OpenGL work is performed by default. Unfortunately many vendors' OpenGL drivers are not really thread-safe and stability is much improved by performing OpenGL work on at most one thread. This is the default behavior of the GLAutoDrawable implementations according to the Threading class. The GLWorkerThread replaces the original AWT event queue thread-based mechanism for two reasons: first, more than one AWT event queue thread may be spawned, for example if a dialog is being shown; second, it avoids blocking the AWT event queue thread during OpenGL rendering.
