It's possible that "it does not require ray tracing" means that it does not require extensions like RTX. Perhaps it uses voxel cone tracing, which you may say is technically not ray tracing, but if you called it ray tracing you wouldn't exactly be wrong either.
- Rusky 6y agoThe article contrasts this approach with voxel cone tracing, so it's not that either.
- dcanelhas 6y agoI would call it Sphere Tracing since that's what it's called in "Hart, John, C; Sphere Tracing: A Geometric Method for the Antialiased Ray Tracing of Implicit Surfaces; The Visual Computer-1995"
- gh123man 6y agoThis was my interpretation. If you want to get technical, Ray tracing != path tracing != ray marching. However people often use them interchangeably.
