Class WGLNVCopyImage

java.lang.Object

org.lwjgl.opengl.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.

Method and Description

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.

                                            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. 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
