Among other disclosure, a computer-implemented method for retaining a surface detail includes identifying a surface that is to be used for generating an image in a rendering process. The surface includes polygons to be changed from an initial size to a larger size as the surface is changed to a lower resolution as part of tessellating the surface. The surface includes at least one surface detail smaller than the larger polygon size. The method includes storing information corresponding to at least a portion of the surface that includes polygons forming the surface detail. The method includes tesselating the surface, wherein the surface assumes the lower resolution. The method includes determining, while the image is at the lower resolution and using the stored information, a shading sample for at least one of the polygons of the larger size that includes the surface detail. The method includes storing the shading sample. |
