Filter Clouds to Surface    

Filters one or more clouds to a surface by proximity and outputs a new point group. Cloud points within the proxim- ity are kept, while cloud points outside of the proximity are removed.

 

Input Arguments

 

0

Collection Object Name Ref List

Cloud Names

One or more point clouds to filter.

1

Collection Object Name

Filter Surface’s Name

The name of the surface to filter to.

2

Collection Object Name

Output Group Name

The name for the resulting point group.

3

Double

Low Proximity

The minimum proximity value. Points above this value (and below the high proximity) will be kept.

4

Double

High Proximity

The maximum proximity value. Points below this

value (and above the low proximity) will be kept.

5

Integer

Skip Factor

A subsampling value to use. For example, if set to 5, only every 5th point will be considered.

6

Output Type

Output Type

Specify whether point clouds or point groups

should be created.

 

Return Arguments

None.

 

Returned Status

 

SUCCESS

The cloud(s) were filtered successfully.

PARTIAL SUCCESS

One or more clouds (but not all) could not be found.

FAILURE

The clouds or filter group could not be found.

 

Remarks

Filter Clouds to Surfaces offers the ability to use an asymmetric distance such as +.1 to +.5 but it ignores edges entirely. This means points beyond an edge are also picked up as long as they are within the specified proximity.

Auto Filter Points/Groups/Clouds to Surface Faces is an alternative that take longer to process, only offsets single proximity value above, below or in both directions but respects edges. This command should be used when edges are of concern.
