Zip-NeRF Added to nerfstudio

Last night a flurry of updates got pushed into nerfstudio. The most exciting of which is a pytorch implementation of Zip-NeRF.

Zip-NeRF is a strong NeRF method from the Google Research team. Once installed, it takes roughly 55 minutes to train on my computer.

Zip-NeRF is the latest 3rd party method to receive support within the Berkeley based studio and has been hotly request, since its paper's release. Late last year, Google researcher and paper author Jon Barron released the code to both CamP and Zip-NeRF. This implementation is different from the official release is this one is built on PyTorch.

In order to install Zip-NeRF, please follow the below instructions.

First, install nerfstudio and its dependencies. Then run:

pip install git+https://github.com/SuLvXiangXin/zipnerf-pytorch#subdirectory=extensions/cuda
pip install git+https://github.com/SuLvXiangXin/zipnerf-pytorch

Finally, install torch_scatter corresponding to your Cuda version(https://pytorch-geometric.com/whl/torch-2.0.1%2Bcu118.html).

In addition to this change, other commits featuring the following were also added.

Before and After



gsplat also received an update to V0.1.5, with the following additions:

  • Improved pytorch implementation of project_gaussians inside _torch_impl.py

  • Screen space blur compensation for rasterizing tiny gaussians from Mip-Splatting

  • Bugfixes

Shrinking 3DGS File Size

Gaussian Splatting has quickly become one of the most exciting research topics in Radiance Fields, thanks to its fast training, real time rendering rates, and easy to create pipeline. The one critique that emerged was the resulting file size from captures, often venturing into the high hundreds of megabytes and up.

RealmDreamer's Generative Scenes

Since the unveiling of the Sora's large-scale generative Radiance Fields, the tech world has been buzzing with anticipation about the future of 3D scene generation. There hasn't been much public work since then showcasing what could be coming, but today we're looking at RealmDreamer, which creates scene level generations based on original text prompts.
