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

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.
