In some use-cases executing such shaders at fragment-rate is actually the preferred behavior. When this extension is enabled, such GLSL shaders will execute at fragment-rate and the built-in will return a per-fragment value. This avoids the significant performance penalty that would otherwise be incurred with sample-rate shading. The following built-ins are affected when this extension is enabled: gl_LastFragData (from EXT_shader_framebuffer_fetch) gl_LastFragDepthARM (from ARM_shader_framebuffer_fetch_depth_stencil) The following built-ins are disallowed when this extension is enabled: gl_SampleID gl_SamplePosition interpolateAtSample() The official definition of this extension is available here: http://www.opengl.org/registry/specs/QCOM/shader_framebuffer_fetch_rate.txt é)ÚplatformÚconstantÚarrays)Ú extensionsÚwrapperN)Ú_typesÚ_glgets)Ú*)Ú_EXTENSION_NAMEcCsddlm}| t¡S)z=Return boolean indicating whether this extension is availabler©r)ÚOpenGLrZhasGLExtensionr r ©r úm/home/ghrups/robot-bench/.venv/lib/python3.9/site-packages/OpenGL/GLES2/QCOM/shader_framebuffer_fetch_rate.pyÚ$glInitShaderFramebufferFetchRateQCOM&s r)Ú__doc__r rrrrrÚctypesZOpenGL.raw.GLES2rrZ3OpenGL.raw.GLES2.QCOM.shader_framebuffer_fetch_rater rr r r rÚs
