GLMINSAMPLESHADING(3G)						  [FIXME: manual]					    GLMINSAMPLESHADING(3G)

NAME

       glMinSampleShading - specifies minimum rate at which sample shaing takes place

C SPECIFICATION

       void glMinSampleShading(GLfloat value);

PARAMETERS

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

DESCRIPTION

       glMinSampleShading 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 indpendently 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.

NOTES

       The 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.

ERRORS

       None.
