'''OpenGL extension NV.conservative_raster This module customises the behaviour of the OpenGL.raw.GL.NV.conservative_raster to provide a more Python-friendly API Overview (from the spec) This extension adds a "conservative" rasterization mode where any pixel that is partially covered, even if no sample location is covered, is treated as fully covered and a corresponding fragment will be shaded. A new control is also added to modify window coordinate snapping precision. These controls can be used to implement "binning" to a low-resolution render target, for example to determine which tiles of a sparse texture need to be populated. An app can construct a framebuffer where there is one pixel per tile in the sparse texture, and adjust the number of subpixel bits such that snapping occurs to the same effective grid as when rendering to the sparse texture. Then triangles should cover (at least) the same pixels in the low-res framebuffer as they do tiles in the sparse texture. The official definition of this extension is available here: http://www.opengl.org/registry/specs/NV/conservative_raster.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.NV.conservative_raster import * from OpenGL.raw.GL.NV.conservative_raster import _EXTENSION_NAME def glInitConservativeRasterNV(): '''Return boolean indicating whether this extension is available''' from OpenGL import extensions return extensions.hasGLExtension( _EXTENSION_NAME ) ### END AUTOGENERATED SECTION
