Note: I am no longer with the University of Utah. I'm still living in Utah, and still occasionally work with some of the people there, but I am no longer a full-time professor there, and thus cannot advice/take on any students.


Short Bio

Ingo Wald is a director of ray tracing at NVIDIA. He received his master's degree from Kaiserslautern University and his PhD from Saarland University (both on ray tracing–related topics). He then served as a post-doctorate at the Max-Planck Institute Saarbruecken, as a research professor at the University of Utah, and as technical lead for Intel's software-defined rendering activities (in particular, Embree and OSPRay). Ingo has coauthored more than 90 papers, multiple patents, and several widely used software projects around ray tracing. His interests still revolve around all aspects of efficient and high-performance ray tracing, from visualization to production rendering, from real-time to offline rendering, and from hard- to software.

"RTX Accelerated Ray Tracing with OptiX" SIGGRAPH course
Course was well attended, and went pretty well. The OptiX 7 tutorial code I wrote for this paper is now available as a public gitlab repo on PDF of presented slides soon to be uploaded to my blog, too.
RTX Space Skipping/Adaptive Sampling paper preprint online.
Our "Efficient Space Skipping and Adaptive Sampling of Unstructured Volumes Using Hardware Accelerated Ray Tracing" paper just got accepted to the short paper track at IEEE Vis 2019. Author's copy now available on my the publications page.
"RTX Beyond Ray Tracing" Paper now online
PDF on this paper on my the publications page. PDF of presented slides soon to be uploaded to my blog, too.
Aug 2018
I moved over to join NVidia.
