3D Gaussian Ray Tracing: Fast Tracing of Particle Scenes
Your browser does not support the video tag.
Abstract
Particle-based representations of radiance fields such as 3D Gaussian Splatting, have found great success for reconstructing and re-rendering of complex scenes.
Most existing methods render particles via rasterization, projecting them to screen space tiles for processing in a sorted order.
This work instead considers ray tracing the particles, building a bounding volume hierarchy and casting a ray for each pixel using high-performance GPU ray...
