'''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. |
