So the “big picture” of what I’m trying to do is create an artificial data set that would mimic the output from a 3D camera. The process I’m attempting to complete is this:

- Define 8 corner points that make up the cube in a ply file.
- Import ply file into paraview, apply Delaunay3D filter to create surfaces.
- Sample (or resample…?) each surface of the cube, ideally in a uniform way (though the ‘uniform’ part isn’t that important). Therefore the total number of points would increase from 8 to an arbitrarily big number.
- Add noise to the x,y,z coordinates of all points.

I’ve got to step 2, but I can’t figure out a way (and I’m not sure if it’s possible) to do step 3. I’ve tried a quite a few filters - e.g. distribute points, extract enclosed points, resample with dataset, and I would of tried point-plane interpolator if it wasn’t greyed out.

Step 4 would be nice if it could be done in Paraview, but is not a really big deal because I could do it in python if need be.

Is what I’m trying to do possible with Paraview? What would be the right process?
