glMinSampleShading — specifies minimum rate at which sample shaing takes place
| ||GLfloat value |
Specifies the rate at which samples are shaded within each covered pixel.
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 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
samples is the value of
GL_SAMPLES for the current framebuffer. At least 1 sample for each covered fragment is generated.
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.
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.
