Thanks for making the project open source.

I tested the trained files provided in the README.
For example, Garden scene,
the Octree-GS Viewer only has a frame rate of 20-30,
whereas the original Inria Viewer and the trained .ply files have a frame rate of 60.

Also, what changes were made to the original Inria Viewer by the Octree-GS Viewer?

What GPU you are using? The results we tested on 3090(24G) are good.
We add some libtorch-based tensor operations and MLP inference to the rendering process.

3060 laptop

Octree-GS contains more tensor operations, so I encourage you to test it on a more powerful GPU.
In addition, we use desktop, which ensures better heat dissipation

Could you explain the modifications that the Octree-GS Viewer made to the original Inria Viewer?

tongji-rkr commented

It mainly include three aspects. Firstly, we get the attributes of anchor from .ply file, and the attributes of Gaussian are obtained according to MLP inference. In addition, we add a selection strategy for anchors. Finally, we added more patterns as well as partial LOD level visualizations

Ok, thanks @tongji-rkr.

Will check diff and find out.
