glMinSampleShading

Name

glMinSampleShading — specifies minimum rate at which sample shading 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 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.

Errors

None.
