| | '''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: |
