Abstract: The present disclosure includes, among other things, systems, methods, and program products for estimating radiant exitance due to subsurface scattering. For example, one or more aspects of the subject matter described in this disclosure can be embodied in one or more methods that include distributing a plurality of sample points across the surface of a 3D object model to be rendered into a 2D image and determining a solid angle subtended by a first sample point and a second sample point relative to a region on the 3D object model. Depending on the determined solid angle relative to a threshold value, a previously determined subsurface scattering contribution for the region or a newly determined subsurface scattering contribution for the region may selectively be used for rendering a portion of the 2D image.

Abstract: The subject matter of this specification can be embodied in, among other things, a method that includes generating intermediate values from an evaluation of one or more static expressions within shader programming code that is configured to modify an appearance of an image, compressing the intermediate values based on a determination of which intermediate values are duplicative, and storing the compressed intermediate values in a buffer accessible to an image rendering application.
