Prerequisites

You can setup the anaconda environment using:

conda env create --file environment.yml
conda activate coherentgs

CUDA 11.7 is strongly recommended.

Data Preparation

You can download the dataset ...

Training

Training on LLFF dataset with 3 views. You can choose from [2, 3, 4] views

python train.py --source_path path/nerf_llff_data/flower --eval --model_path output/flower --num_cameras 3

Rendering

Run the following script to render the video.

python renderpath.py -source_path path/nerf_llff_data/flower --eval --model_path output/flower

Acknowledgement

The repo is built on top of 3D Gaussian Splatting
The modified rasterizer to render depth and eval script is from FSGS
