WebNeRF that is the hierarchical coarse-to-fine sampling of points along rays, by replacing the heuristic non-trainable sample proposal module with a fully end-to-end trainable one. This is complementary to many of the above-mentioned approaches, e.g. [3, 14, 25, 33, 40, 54, 57, 60], since they also use WebHierarchical volume sampling. If you think about it, uniformly sampling points along the camera ray is not very efficient, many points will fall into free space or occluded regions that do not contribute to the rendered …

NeRF将场景建模成一个连续的5D辐射场（其实感觉就可以理解为隐式的体素描述）。. 已知场景中点的位置 (x,y,z) 和观察方向 (\theta,\phi) ，神经网络 F ...
