Creating realistic computer graphics for video games, extended reality, and scientific visualization tools have remained one of the challenges in the graphic development industry. Now, scientists at Dartmouth created new software techniques that can make more realistic computer-generated images.
"Over the last decade, ray tracing has dramatically increased the realism and visual richness of computer-generated images in movies where producing just a single frame can take hours," said Wojciech Jarosz, an associate professor of computer science at Dartmouth who served as the senior researcher for both projects. "Our papers describe two very different approaches for bringing realistic ray-traced lighting to the constraints of real time graphics."

histicated lighting effects. The study also highlights the importance of the illusion of interactivity and discusses the new technique ‘reservoir-based spatiotemporal importance resampling (ReSTIR)’.
"This technology is not just exciting for what it can bring to real-time applications like games, but also its impact in the movie industry and beyond," said Benedikt Bitterli, a PhD student at Dartmouth who served as the first author of a research paper on the technique.
