void dispose(final GLAutoDrawable drawable)
Notifies the listener to perform the release of all OpenGL resources per GLContext,...
void display(final GLAutoDrawable drawable)
Called by the drawable to initiate OpenGL rendering by the client.
void write(final File dest)
Write the TextureData filled by readPixels(GLAutoDrawable, boolean) to file.
A higher-level abstraction than GLDrawable which supplies an event based mechanism (GLEventListener) ...
An abstraction for an OpenGL rendering target.
