Multisampling differs from supersampling in that the color of a primitive that covers all or part of a pixel is resolved once, regardless of the number of samples covered. If a large polygon is rendered, the colors of all samples in each interior pixel will be the same. This suggests a simple compression scheme that can reduce the necessary memory bandwidth requirements. In one such scheme, each sample is stored in a separate slice of the multisample surface. An additional multisample control surface (MCS) contains a mapping from pixel samples to slices. If all the values stored in the MCS for a particular pixel are the same, then all the samples have the same value. Applications can take advantage of this information to reduce the bandwidth of reading multisample textures. A custom multisample resolve filter could optimize resolving pixels where every sample is identical by reading the color once. color = texelFetch(sampler, coordinate, 0); if (!textureSamplesIdenticalEXT(sampler, coordinate)) { for (int i = 1; i < MAX_SAMPLES; i++) { vec4 c = texelFetch(sampler, coordinate, i); //... accumulate c into color } } The official definition of this extension is available here: http://www.opengl.org/registry/specs/EXT/shader_samples_identical.txt é)ÚplatformÚconstantÚarrays)Ú extensionsÚwrapperN)Ú_typesÚ_glgets)Ú*)Ú_EXTENSION_NAMEcó:•SSKJn UR"[5$)z=Return boolean indicating whether this extension is availabler©r)ÚOpenGLrÚhasGLExtensionr r s Úc/home/wildlama/miniconda3/lib/python3.13/site-packages/OpenGL/GLES2/EXT/shader_samples_identical.pyÚglInitShaderSamplesIdenticalEXTr.s€å!Ø × $Ò $¤oÓ 7Ð7ó)Ú__doc__rrrrrrÚctypesÚOpenGL.raw.GLES2rr Ú-OpenGL.raw.GLES2.EXT.shader_samples_identicalr r©rrÚrs'ðñ%÷L.Ñ-ß&Û ß,Ü;ÝIó8r
