Patent ID: 8674988

Claim:
A shading method for use by a computer system having a processor and a memory, the method comprising: providing, using the processor, a user with control over separately defining values for each of the subcomponents of a light scattering by one or more fibers using a user interface, wherein each of the subcomponents controls a different visually apparent characteristic of the one or more fibers; receiving, using the processor, from the user, the values of each of the subcomponents of the light scattering by the one or more fibers; storing, using the processor, the values of each of the subcomponents in the memory; combining, using the processor, the values of each of the subcomponents to determine pixel values for the one or more fibers; and displaying, using the processor, the one or more fibers using the pixel values on a display; wherein the one or more fibers are hair or fur fibers, and wherein the subcomponents of the light include: a light that reflects off an outer surface of the one or more fibers (“R”); a light that has transmitted through the one or more fibers (“TT”); and a light that has been internally reflected off an inner surface of the one or more fibers (“TRT”).
