About anisotropy regularizer #18

Hi, Thank you for your great work! I am interested in your work and have a few questions about the anisotropy regularizer in Section 3.8 of the paper. Is it implemented in the released code? Is it applied only during the reconstruction of the static scene using 3D Gaussian Splatting? What are the suggestions for the hyperparameter r used in this loss？ Thank you！

Hi,

Thanks for your interest! The anisotropy regularizer is currently not included in this repo. Yes, it's only applied during the static scene reconstruction and it's optional. Our experiment results suggest r=3 or 4 works well generally.

Best, Tianyi
