UI+NMT Joint Computer Science Colloquium


Path Tracing

Keith Jeffery
DreamWorks Animation

Date: Monday November 7, 2022
Time: 5:30pm MST
Room: Zoom zoom.us, Meeting ID 926 9565 5625 passcode 488975
            The talk will be delivered by zoom and shown in Speare Hall room 19 for the CSE 585 class

   Abstract:

Path tracing, used to render the 3D effects in most feature files and the final frames in 3D animated feature films, is time and energy-consuming. This talk will explain the path tracing algorithm and investigate two methods DreamWorks Animation uses to reduce the cost of rendering: a large-scale SIMD (single instruction, multiple data) architecture and a low-contention adaptive sampling framework.
