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
