NAMEglMinSampleShading − specifies minimum rate at which sample shaing takes place

C SPECIFICATIONvoid glMinSampleShading(GLfloat value);

PARAMETERSvalue Specifies the rate at which samples are shaded within each covered pixel​.

DESCRIPTIONglMinSampleShading specifies the rate at which samples are shaded within a covered pixel​. Sample−rate shading is enabled by calling glEnable() with the parameter GL_SAMPLE_SHADING​. If GL_MULTISAMPLE or GL_SAMPLE_SHADING is disabled, sample shading has no effect​. Otherwise, an implementation must provide at least as many unique color values for each covered fragment as specified by value times samples where samples is the value of GL_SAMPLES for the current framebuffer​. At least 1 sample for each covered fragment is generated​. A value of 1​.0 indicates that each sample in the framebuffer should be independently shaded​. A value of 0​.0 effectively allows the GL to ignore sample rate shading​. Any value between 0​.0 and 1​.0 allows the GL to shade only a subset of the total samples within each covered fragment​. Which samples are shaded and the algorithm used to select that subset of the fragment's samples is implementation dependent​.

NOTESThe type of the value parameter was changed from GLclampf to GLfloat​. This change is transparent to user code and is described in detail on the removedTypes() page​.

ERRORSNone​.
