CHICAGO—SIGGRAPH 2020 featured a vast lineup of emerging technology demos, research, and sessions that shine a light on what’s new in ray tracing innovations. This year, the SIGGRAPH conference hosted the first fully virtual event in its history. Participants were able to learn about ray tracing advancements on demand and during scheduled sessions, with content accessible through 27 October.
Spanning everything from new rendering pipelines, applications in projection mapping, path tracing, spatial hashing, real-time rendering, ambient and partial occlusion, depth of field, and motion blur rendering, the computer graphics community has left no stone unturned. In addition to juried selections across multiple conference programs, SIGGRAPH 2020 exhibitors also shared demos and insights on their latest work in ray tracing.
“The SIGGRAPH Posters program selected some truly incredible research this year that just so happens to include several projects which offer new approaches to ray tracing technology,” noted SIGGRAPH 2020 Posters Chair Ana Cecilia Balliache Liendo, of Schell Games. “The inspiring, industry-leading contributions from across the computer graphics and interactive techniques research communities unite us and are sure to provoke even more dialogue and innovation around the possibilities of this tech in the future.”
