Normal or High Compression option:

Remove points who's distance to a neighbour is less then the value specified.  Specifying a higher value will remove more points resulting in a grid like appearance.


Note: Default value does not normally need changing.


Voxel option:

Sets the quality of the created Voxel model.  Default is 200mm, but values of 20mm or 50mm will yield greater results, but file size will increase.

Resulting Voxel model file size can be 4000x times smaller then original point cloud.
