3D Gaussian Splatting scene. Shrink .PLY file for faster interaction

Beginners

I am toying with a 3D Gaussian Splatting scene

Is there a way to shrink the detail of a ,ply file in Blender or Cloudcompare?

Gaussian Splats need a large amount of data to create such a photorealistic render.
You can use supersplat to crop sections of the splat and reduce the file size somewhat.
I don’t know about Blender, but CloudCompare is for editing point clouds. While you can edit a .ply file in it, crop/subsample, etc., any attempts to use it as a splat after saving it out seem to fail. I tested with the Gaussian splitting tool created by y=fx & supersplat and got the same results.

Yeah as @Hazetheai pointed out, supersplat is your best option to make the size smaller. You can do it in blender with the 3DGS plugin and export the splat out of there, but supersplat renders faster and has easier to use tools.

Also check out @watershed new GS tox, it’s probably the best splatting toolkit in TD at the moment.

I was able to rotate and save out my .ply from Blender to get it to center.

I was wondering if I can delete geometry.

You can go into edit mode in blender, use the point select and delete points in blender if needed. I would suggest doing it in supersplat since the tools are a little more geared towards working with splats.

supersplat is the best option ive found for pure pre-processing using a gui
