Researchers have developed RAGA, a novel method for real-time ray-traced shadow casting within 3D Gaussian Splatting (3DGS) scenes. This approach computes shadows directly in Gaussian space, eliminating the need for mesh reconstruction and offering improved realism and temporal stability for animated avatars and object interactions. The RAGA formulation utilizes exact ray-Gaussian line integrals to determine occlusion weights and incorporates an avatar proxy representation to mitigate temporal variance, achieving shadow casting rates of approximately 50 FPS.
