1'''OpenGL extension AMD.sample_positions 2 3This module customises the behaviour of the 4OpenGL.raw.GL.AMD.sample_positions to provide a more 5Python-friendly API 6 7Overview (from the spec) 8 9 This extension provides a mechanism to explicitly set sample positions for a 10 FBO with multi-sampled attachments. The FBO will use identical sample locations 11 for all pixels in each attachment. This forces TEXTURE_FIXED_SAMPLE_LOCATIONS 12 to TRUE if a multi-sampled texture is specified using TexImage2DMultisample 13 or TexImage3DMultisample. That is, using GetTexLevelParameter to query 14 TEXTURE_FIXED_SAMPLE_LOCATIONS will always return TRUE if the mechanism is 15 explicitly used to set the sample positions. 16 17The official definition of this extension is available here: 18http://www.opengl.org/registry/specs/AMD/sample_positions.txt 19''' 20from OpenGL import platform, constant, arrays 21from OpenGL import extensions, wrapper 22import ctypes 23from OpenGL.raw.GL import _types, _glgets 24from OpenGL.raw.GL.AMD.sample_positions import * 25from OpenGL.raw.GL.AMD.sample_positions import _EXTENSION_NAME 26 27def glInitSamplePositionsAMD(): 28 '''Return boolean indicating whether this extension is available''' 29 from OpenGL import extensions 30 return extensions.hasGLExtension( _EXTENSION_NAME ) 31 32glSetMultisamplefvAMD=wrapper.wrapper(glSetMultisamplefvAMD).setInputArraySize( 33 'val', 2 34) 35### END AUTOGENERATED SECTION
