A computationally efficient method for rendering skin tissue to achieve
lifelike results includes application of a blurring algorithm to a
two-dimensional light map. The algorithm is compact and is not derived
from complex mathematical models of subsurface scattering in translucent
materials, and yet achieves results similar to more complex models. The
method includes receiving three-dimensional surface geometry relating to
a digital object and other information for defining modeled light
reflected from the surface, generating a two-dimensional matrix of light
intensity values mapped to the surface geometry, blurring the matrix
using a compact algorithm, and rendering the object using the blurred
light intensity values.
