'''OpenGL extension ARB.shader_ballot This module customises the behaviour of the OpenGL.raw.GL.ARB.shader_ballot to provide a more Python-friendly API Overview (from the spec) This extension provides the ability for a group of invocations which execute in lockstep to do limited forms of cross-invocation communication via a group broadcast of a invocation value, or broadcast of a bitarray representing a predicate value from each invocation in the group. The official definition of this extension is available here: http://www.opengl.org/registry/specs/ARB/shader_ballot.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.ARB.shader_ballot import * from OpenGL.raw.GL.ARB.shader_ballot import _EXTENSION_NAME def glInitShaderBallotARB(): '''Return boolean indicating whether this extension is available''' from OpenGL import extensions return extensions.hasGLExtension( _EXTENSION_NAME ) ### END AUTOGENERATED SECTION
