I have a point data set (lets call it A) and an stl mesh. I used point dataset interpolator to get the distribution on the mesh (output A). Now i have another point dataset (lets call it B). I want to get its distribution onto the same output A instead of a new output B.

I tried using Resample with Dataset, using point cloud B as source and output A as target (also tried source: output B and target: output A), but I don’t get both scalars (point cloud A and B) on the Resample with Dataset output.

Ideal scenario is to interpolate both point clouds on to the same mesh and export it as a single .vtk file with 2 sets of scalar values (feature maps) in it.

Any directions on what I am doing wrong?

Thank you in advance

One way to do this is to use the same method that was used to create Output A, i.e., the point dataset interpolator, to create Output B as well. Then, while holding down the Ctrl key, select both Output A and Output B in the tree and apply the Append Attributes filter.
