Question

• Q1. Different hyperparameters from the original paper
• A1. There are many combinations between these hyperparameters. You are free to balance the training speed and accuracy by modify them.
• Q2. When will NeRF-Tree released?
• A2. Hard to say a specific date. The data structure NeRF-Tree is closed to Octree.

Progress

More scenes and applications will be suported soon. Stay tune!
