Adding lights and shadow casting

[LaFeuilleMorte]

Hi, there're many lighting methods for the gaussian splatting recently, do you plan to add lights to this project (like shadow casting, changing environment light conditions)?

Hi!

Yes would be great. Do you have any links to examples?

Thanks

Hi, this blog has some clues: https://andrewkchan.dev/posts/lit-splat.html;
And these two papers:

https://nju-3dv.github.io/projects/Relightable3DGaussian/
https://asparagus15.github.io/GaussianShader.github.io/

I think if we can render depth map of gaussians, it would be easy to apply shadow mapping like in traditional CG in this viewer.
