Thanks for your interest. We tested NeuDA on the Nvidia V100 GPU, NeuDA is a bit faster than NeuS. NeuDA has a less time cost on each iteration since it employs a shallower MLP (4 vs. 8 for NeuS). Besides, NeuDA leverages deformable anchor grids instead of hash grids to achieve better convergence. But NeuDA is slower than Instant-NGP in this implementation because there are some accelerated strategies (such as occupancy grids and fully fused MLPs) used in Instant-NGP not implemented in this repo.
Hi, thanks for your great job!
I run the code on an NVIDIA A100 GPU (following neuda_wmask.conf), and the complete training time cost ~5 hours, which is similar to NeuS. This confuses me. As NeuDA leverages hash-table as instant-NGP, shouldn't NeuDA converges faster than NeuS?
Looking forward to you reply!!!
