I have a very basic question I have a light direction vector using CDXUTDirectionWidget (part of DXUT) which I can move around in my scene but I wish to cook the light position out of it. My question is how can I get the position vector given a direction vector? [Edited by - rcpedersen on September 12, 2005 6:18:22 AM]
