Class GLXSGIMakeCurrentRead


  • public class GLXSGIMakeCurrentRead
extends java.lang.Object
    Native bindings to the GLX_SGI_make_current_read extension.

    The association of the current context with a drawable is extended to allow separate write and read drawables. This paves the way for allowing preprocessing of image data in an "off screen" window which is then read into the visible window for final display. Similarly it sets the frame-work for direct transfer of video to the GL, by treating the video as a special kind of read drawable (a.k.a, readable).
