WebNov 30, 2024 · Unfortunately i do not understand their method of probe placement. It sounds like they place probes on a static regular grid, and if they collide with the SDF scene, the probe moves out of solid space by following the distance gradient. But it seems they do this at runtime, maybe to react on dynamic objects. Imagine a moving wall. flannel mens jacket with hood

"WebAbstract. Neural signed distance functions (SDFs) are emerging as an effective representation for 3D shapes. SDFs encode 3D surfaces with a function of position that returns the closest distance to a surface. State-of-the-art methods typically encode the SDF with a large, fixed-size neural network to approximate complex shapes with implicit ... " - Gradiant of sdf field
