Detailed Description

Checkerboard pass renders scene to a multi-sample target with checkerboard pattern The checkerboard will be shifted one pixel between odd and even frames In this customized pass, it creates two imported attachment images to save last frame's color and depth buffer And it also shifts the viewport for the checkerboard pattern

The documentation for this class was generated from the following file:
