Use this function to apply different search width for the lefthand and righthand side.
Use this function to filter away terrain points in the terrain cross-sections. This is typically used when the terrain profiles is very rich in data with dense triangulation.
Vertical tolerance - defines the vertical distance to filter. Points with vertical distance within this value will be filtered.
Minimum horizontal distance - defines the minimum distance between points that is needed to allow filtering.
Vertical tolerance: 10cm
Minimum horizontal distance: 1cm
This will filter points with less than 10cm vertical distance that also has more than 1cm horizontal distance. This will save points that are fairly close to one another (less than 1cm horizontal distance).
