'''OpenGL extension EXT.stencil_two_side This module customises the behaviour of the OpenGL.raw.GL.EXT.stencil_two_side to provide a more Python-friendly API Overview (from the spec) This extension provides two-sided stencil testing where the stencil-related state (stencil operations, reference value, compare mask, and write mask) may be different for front- and back-facing polygons. Two-sided stencil testing may improve the performance of stenciled shadow volume and Constructive Solid Geometry (CSG) rendering algorithms. The official definition of this extension is available here: http://www.opengl.org/registry/specs/EXT/stencil_two_side.txt ''' from OpenGL import platform, constant, arrays from OpenGL import extensions, wrapper import ctypes from OpenGL.raw.GL import _types, _glgets from OpenGL.raw.GL.EXT.stencil_two_side import * from OpenGL.raw.GL.EXT.stencil_two_side import _EXTENSION_NAME def glInitStencilTwoSideEXT(): '''Return boolean indicating whether this extension is available''' from OpenGL import extensions return extensions.hasGLExtension( _EXTENSION_NAME ) ### END AUTOGENERATED SECTION
