'''OpenGL extension SGIX.texture_scale_bias This module customises the behaviour of the OpenGL.raw.GL.SGIX.texture_scale_bias to provide a more Python-friendly API Overview (from the spec) This extension adds scale, bias, and clamp to [0, 1] operations to the texture pipeline. These operations are applied to the filtered result of a texture lookup, before that result is used in the texture environment equations and before the texture color lookup table of SGI_texture_color_table, if that extension exists. These operations are distinct from the scale, bias, and clamp operations that appear in the SGI_color_table extension, which are used to define a color lookup table. Scale and bias operations on texels can be used to better utilize the color resolution of a particular texture internal format (see EXT_texture). The official definition of this extension is available here: http://www.opengl.org/registry/specs/SGIX/texture_scale_bias.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.SGIX.texture_scale_bias import * from OpenGL.raw.GL.SGIX.texture_scale_bias import _EXTENSION_NAME def glInitTextureScaleBiasSGIX(): '''Return boolean indicating whether this extension is available''' from OpenGL import extensions return extensions.hasGLExtension( _EXTENSION_NAME ) ### END AUTOGENERATED SECTION
