interpolateAtOffset 3G
interpolateAtOffset sample a varying at specified offset from the center of a pixel

## Declaration

float `interpolateAtOffset` float interpolant vec2 offset vec2 `interpolateAtOffset` vec2 interpolant vec2 offset vec3 `interpolateAtOffset` vec3 interpolant vec2 offset vec4 `interpolateAtOffset` vec4 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.
