Question About Surface Trimmer Algorithm Steps

[RainSureZhao]

Hello, sorry to bother you. I would like to know your basic algorithm principle when implementing Surface Trimmer.

The basic idea is that, using the distribution of the samples, one can define a function which assigns a measure of the sampling density to each point in 3D. During the reconstruction phase, this function is sampled at the vertex positions, so that the output mesh "carries" a (per-vertex) scalar function

Then, as a post-process, one trims off the parts of the surface where the sampling density is below a prescribed value.

I got it! Thank you very much!
