| There are two filter options. The first option is to filter by adjacent triangle normal angle filter. The second option is to filter by using the VTK Decimate Pro.

| * '''Filter – Adjacent Triangle Normal Angle Filter'''
| |
| Redundant and overlapping data may exist in a scatter. SMS offers the ability to filter the data and remove unnecessary data points in relatively flat areas in the ''Filter'' option from the Scatter module, ''Data'' menu. The user specifies an angle. Each data point is checked to see if it is in a flat region by dotting the normals of the surrounding triangles.

| If the normals are all within the specified angle, the region is flat and the point is deleted.

| * '''Filter – VTK Decimate Pro'''
| |
| VTK Decimate Pro is a filter to reduce the number of triangles in a triangle mesh, forming a good approximation to the original geometry. To get a detailed description of the options to set when performing this kind of filter, please visit the website:
