| '''OpenGL extension ATI.element_array |
| |
| This module customises the behaviour of the |
| OpenGL.raw.GL.ATI.element_array to provide a more |
| Python-friendly API |
| |
| Overview (from the spec) |
| |
| This extension provides a mechanism for an application to create |
| an array of index data for use in specifying geometric primitives. |
| |
| This extension is most useful when used in conjunction with the |
| ATI_vertex_array_object extension. ATI_vertex_array_object |
| provides an interface for storing vertex array data in persistent, |
| hardware-addressable memory. In cases where large amounts of |
| vertex data are in use, the index data used to construct |
| primitives (typically as passed to the GL through DrawElements) |
| can impose a significant bandwidth burden. ATI_element_array |
| allows the application to specify independent arrays of elements, |
| which can then be cached using ATI_vertex_array_object. |
| |
| |
| The official definition of this extension is available here: |
