OpenGL.GL.ATI.pn_triangles

OpenGL extension ATI.pn_triangles

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

Overview (from the spec)

ATI_pn_triangles provides a path for enabling the GL to internally tessellate input geometry into curved patches. The extension allows the user to tune the amount of tessellation to be performed on each triangle as a global state value. The intent of PN Triangle tessellation is typically to produce geometry with a smoother silhouette and more organic shape.

The tessellated patch will replace the triangles input into the GL. The GL will generate new vertices in object-space, prior to geometry transformation. Only the vertices and normals are required to produce proper results, and the rest of the information per vertex is interpolated linearly across the patch.

The official definition of this extension is available here: http://www.opengl.org/registry/specs/ATI/pn_triangles.txt
