I'm using meshlab to process a dense point cloud right now. I'm trying to remove some points that have radius bigger than a certain number from the center, but could not get Meshlab to select those points. I'm using Conditional Vertex Selection, but the (rad > 0) function is not selecting any point at all. I also centered the bounding box at the origin.

enter image description here

Does anyone know what the problem is? Thanks!

I'm not really sure what the "rad" variable refers to, but I don't think it is a spherical distance from the center. However if you want to select vertices larger than a spherical radius from the center, you can use something like (sqrt(x^2+y^2+z^2) >= 100), replacing 100 with whatever radius you want.

Shameless plug: MLX incorporates both cylindrical and spherical selection shortcuts as functions mlx.select.cylindrical_vert & mlx.select.spherical_vert.
