Class ARBWindowPos


  • public class ARBWindowPos
extends java.lang.Object
    Native bindings to the ARB_window_pos extension.

    In order to set the current raster position to a specific window coordinate with the RasterPos2i command, the modelview matrix, projection matrix and viewport must be set very carefully. Furthermore, if the desired window coordinate is outside of the window's bounds one must rely on a subtle side-effect of the Bitmap command in order to avoid frustum clipping.

    This extension provides a set of functions to directly set the current raster position in window coordinates, bypassing the modelview matrix, the projection matrix and the viewport-to-window mapping. Furthermore, clip testing is not performed, so that the current raster position is always valid.

    This greatly simplifies the process of setting the current raster position to a specific window coordinate prior to calling DrawPixels, CopyPixels or Bitmap. Many matrix operations can be avoided when mixing 2D and 3D rendering.

    Promoted to core in OpenGL 1.4.
