'''OpenGL extension OES.sample_shading This module customises the behaviour of the OpenGL.raw.GLES2.OES.sample_shading to provide a more Python-friendly API Overview (from the spec) In standard multisample rendering, an implementation is allowed to assign the same sets of fragment shader input values to each sample. This can cause aliasing where the fragment shader input values are used to generate a result that doesn't antialias itself, for example with alpha-tested transparency. This extension adds the ability to explicitly request that an implementation use a minimum number of unique set of fragment computation inputs when multisampling a pixel. Specifying such a requirement can reduce aliasing that results from evaluating the fragment computations too few times per pixel. This extension adds new global state that controls the minimum number of samples for which attribute data is independently interpolated. When enabled, all fragment-shading operations are executed independently on each sample. The official definition of this extension is available here: http://www.opengl.org/registry/specs/OES/sample_shading.txt ''' from OpenGL import platform, constant, arrays from OpenGL import extensions, wrapper import ctypes from OpenGL.raw.GLES2 import _types, _glgets from OpenGL.raw.GLES2.OES.sample_shading import * from OpenGL.raw.GLES2.OES.sample_shading import _EXTENSION_NAME def glInitSampleShadingOES(): '''Return boolean indicating whether this extension is available''' from OpenGL import extensions return extensions.hasGLExtension( _EXTENSION_NAME ) ### END AUTOGENERATED SECTION
