Resample with dataset when data is contained in main axis planes

Dear support,

I am trying to interpolate a point cloud contained in the ZX axis (so the bounding box of the dataset is zero in the Y direction with Delta Y = 0) into a much more dense mesh using the snap to closest cell option, I don’t care if values are repeated for this application. I have tried to play with the tolerance to help the filter finding the point around each cell but I am having 1e-38 values in the faces that are contained in the ZX, XY or ZY. Then I am wondering if having a bounding box with zero volume causes issues when computing the points finding distance through the tolerance value (if that distance is computed proportionally to the cubic root of the bounding box volume, it will be always zero).

Could someone give more info about this method?

I’ve found a way to bypass it which is using a transform filter to rotate the coordinates around an axis, so the face now has 3D dimensions and a bounding box with volume larger than zero, interpolate in that new position and then undo the rotation to have the original location.

Weird but it works :sweat_smile:
