- vec2 interpolateAtOffset(vec2 interpolant, vec2 offset);

PARAMETERS
interpolant
-
- Specifies the interpolant to be sampled at the specified offset.
offset
- Specifies the offset from the center of the pixel at which to sample interpolant.
DESCRIPTION
interpolateAtOffset returns the value of the input varying interpolant sampled at an offset from the center of the pixel specified by offset. The two floating-point components of offset give the offset in pixels in the x and y directions from the center of the pixel, respectively. An offset of (0, 0) identifies the center of the pixel. The range and granularity of offsets supported by this function is implementation-dependent.
