| '''OpenGL extension NV.copy_image |
| |
| This module customises the behaviour of the |
| OpenGL.raw.GL.NV.copy_image to provide a more |
| Python-friendly API |
| |
| Overview (from the spec) |
| |
| 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 and GLX versions allow copying between images in different |
| contexts, even if those contexts are in different sharelists or |
| even on different physical devices. |
| |
| The official definition of this extension is available here: |
| http://www.opengl.org/registry/specs/NV/copy_image.txt |
