How to Colorize the Reconstructed Surface of Point Clouds Using Scalar Values?

I have a set of three-dimensional point clouds with associated scalar values. I want to perform surface reconstruction using these point clouds and then color the surface based on the scalar values of each point. However, I have noticed that the number of points increases after the surface reconstruction, and I’m unsure about the scalar values of these additional points. Can you please guide me on how to achieve the desired function?


vtkProbeFilter does what you need. Please, read about it here: (there is also a link to some examples).
