edit splats or point clouds

[ehatami65]

Hi, Thanks for the awesome repo! similar to mesh selection feature, could we get similar interactive selection for point clouds or Gaussian splats? I am looking for a way to select (using mouse drag a box or 3d contour and then edit them (e.g., delete, change color) directly in the scene in an interactive way. thanks

Hi @ehatami65!

I think we might not have the bandwidth to do something very specialized for this in the near future, but there are some existing features that might be helpful for this:

• For selecting individual Gaussians, how we do vertex click events in this example might be helpful:
  • https://viser.studio/main/examples/demos/smpl_visualizer/
• You could also manually compute intersecting Gaussians with the generic "rect-select" pointer event:
  • https://viser.studio/main/examples/interaction/scene_pointer/

Would these work?
