| | '''OpenGL extension ATI.texture_mirror_once |
| | |
| | This module customises the behaviour of the |
| | OpenGL.raw.GL.ATI.texture_mirror_once to provide a more |
| | Python-friendly API |
| | |
| | Overview (from the spec) |
| | |
| | ATI_texture_mirror_once extends the set of texture wrap modes to |
| | include two modes (GL_MIRROR_CLAMP_ATI, GL_MIRROR_CLAMP_TO_EDGE_ATI) |
| | that effectively use a texture map twice as large as the original image |
| | in which the additional half of the new image is a mirror image of the |
| | original image. |
| | |
| | This new mode relaxes the need to generate images whose opposite edges |
| | match by using the original image to generate a matching "mirror image". |
| | This mode allows the texture to be mirrored only once in the negative |
| | s, t, and r directions. |
| | |
