glMinSampleShading — specifies minimum rate at which sample shading takes place
void glMinSampleShading(
|
GLfloat value); |
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. If the value of GL_SAMPLE_BUFFERS is zero,
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.
None.
