Each configuration was trained for 11000 steps using our fast NeRF implementation, varying only the input encoding and the neural network size. The number of trainable parameters (neural network weights + encoding parameters) and training time are shown below each image.
WebJan 12, 2024 · The original Nerf uses trigonometric functions to encode large scenes, and the sparsity of spatial encoding makes the model unable to represent the details of large scenes well. Under hash coding, when the number level is equal to 11, it can also achieve high-precision RSDE indicators while ensuring a certain color rendering quality.
