'''OpenGL extension ARB.draw_buffers
This module customises the behaviour of the OpenGL.raw.GL.ARB.draw_buffers to provide a more Python-friendly API
Overview (from the spec) This extension extends ARB_fragment_program and ARB_fragment_shader to allow multiple output colors, and provides a mechanism for directing those outputs to multiple color buffers.
The official definition of this extension is available here: http://www.opengl.org/registry/specs/ARB/draw_buffers.txt ''' from OpenGL import platform, constants, constant, arrays from OpenGL import extensions, wrapper from OpenGL.GL import glget import ctypes from OpenGL.raw.GL.ARB.draw_buffers import * ### END AUTOGENERATED SECTION from OpenGL.lazywrapper import lazy @lazy( glDrawBuffersARB ) def glDrawBuffersARB( baseOperation, n=None, bufs=None ): """glDrawBuffersARB( bufs ) -> bufs Wrapper will calculate n from dims of bufs if only one argument is provided... """ if bufs is None: bufs = n n = None bufs = arrays.GLenumArray.asArray( bufs ) if n is None: n = arrays.GLenumArray.arraySize( bufs ) return baseOperation( n,bufs )
from OpenGL.GL import glget glget.addGLGetConstant( GL_MAX_DRAW_BUFFERS_ARB, (1,) ) # Should have output arrays for the buffers too???
