NAME

       interpolateAtCentroid - sample a varying at the centroid of a pixel

DECLARATION

       float interpolateAtCentroid(float interpolant);

       vec2 interpolateAtCentroid(vec2 interpolant);

       vec3 interpolateAtCentroid(vec3 interpolant);

       vec4 interpolateAtCentroid(vec4 interpolant);

PARAMETERS

       interpolant
           Specifies the interpolant to be sampled at the pixel centroid.

DESCRIPTION

       interpolateAtCentroid returns the value of the input varying interpolant sampled at a
       location inside both the pixel and the primitive being processed. The value obtained would
       be the value assigned to the input variable if declared with the centroid qualifier.
