1. A computer-implemented method for computing a texture color, the method comprising:
determining a surface spread angle at a first point where a ray cone intersects a first surface within a graphics scene based on one or more differential barycentric coordinates at the first point;
determining, based on the surface spread angle, a width of a reflected ray cone at a second point where the reflected ray cone intersects a second surface within the graphics scene; and
computing the texture color based on the width of the reflected ray cone.
