OpenGL.GL.EXT.vertex_array

OpenGL extension EXT.vertex_array

This module customises the behaviour of the OpenGL.raw.GL.EXT.vertex_array to provide a more Python-friendly API

Overview (from the spec)

This extension adds the ability to specify multiple geometric primitives with very few subroutine calls. Instead of calling an OpenGL procedure to pass each individual vertex, normal, or color, separate arrays of vertexes, normals, and colors are prespecified, and are used to define a sequence of primitives (all of the same type) when a single call is made to DrawArraysEXT. A stride mechanism is provided so that an application can choose to keep all vertex data staggered in a single array, or sparsely in separate arrays. Single-array storage may optimize performance on some implementations.

This extension also supports the rendering of individual array elements, each specified as an index into the enabled arrays.
