Before coming to Columbia I worked as a software engineer in the render team at Rhythm & Hues Studios. Our software was responsible for calculating lighting effects such as shadows and reflections to compute photoreal synthetic images. My largest responsibilities were shadowing and subsurface scattering. The Aslan character on the left was rigged, animated, simulated, rendered, and composited using proprietary software at Rhythm and Hues.
