Another approach for Tutorial 14, Transmittance

Posted on March 11, 2010 by

Matthew Vitelli provided me with another approach to the transmittance technique. What he is doing is to compute the transmission specially for each object. This would allow you to have specialized Du and C components for each object and also … Continue reading →
