OpenGL.GL.ATI.element_array

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: http://www.opengl.org/registry/specs/ATI/element_array.txt
