Package org.lwjgl.opengl

Class WGLNVCopyImage


  • public class WGLNVCopyImage
extends java.lang.Object
    Native bindings to the WGL_NV_copy_image extension.

    This extension enables efficient image data transfer between image objects (i.e. textures and renderbuffers) without the need to bind the objects or otherwise configure the rendering pipeline. The WGL version allows copying between images in different contexts, even if those contexts are in different sharelists or even on different physical devices.

      static boolean wglCopyImageSubDataNV(long srcRC, int srcName, int srcTarget, int srcLevel, int srcX, int srcY, int srcZ, long dstRC, int dstName, int dstTarget, int dstLevel, int dstX, int dstY, int dstZ, int width, int height, int depth)
      Behaves identically to the core function CopyImageSubDataNV, except that the srcRC and dstRC parameters specify the contexts in which to look up the source and destination objects, respectively.

        Behaves identically to the core function CopyImageSubDataNV, except that the srcRC and dstRC parameters specify the contexts in which to look up the source and destination objects, respectively. A value of zero indicates that the currently bound context should be used instead.
        Parameters:
        srcRC - the source OpenGL context
        srcName - the source object
        srcTarget - the source object target
        srcLevel - the source level-of-detail number
        srcX - the source texel x coordinate
        srcY - the source texel y coordinate
        srcZ - the source texel z coordinate
        dstRC - the destination OpenGL context
        dstName - the destination object
        dstTarget - the destination object target
        dstLevel - the destination level-of-detail number
        dstX - the destination texel x coordinate
        dstY - the destination texel y coordinate
        dstZ - the destination texel z coordinate
        width - the number of texels to copy in the x-dimension
        height - the number of texels to copy in the y-dimension
        depth - the number of texels to copy in the z-dimension
