Filtering Clouds to Points
Given a set of clouds and a set of points, SA can filter the clouds to the points. You provide a desired proximity and maximum number of points, and choose the existing points to serve as filter points. SA will create a new point group containing a subsampled set of up to the prescribed number of points (within the proximity) for each filter point.
This command is useful, for instance, when you have a set of nominal points on a design surface that indicates where you’d like to measure, and you have a surface scan of the part. The command will filter the clouds to those points.
To Filter Clouds to Reference Points:
-
From the menu, select Construct>Points>From Cloud Points>Filter Clouds to Points.
-
Select the points to use as filter points.
-
Pick one or more clouds to filter.
-
At the prompt, specify the resulting group name.
-
Enter a filter proximity—the maximum distance that a resulting cloud point can be from a filter point. Entering 0 will create a point only at the closest cloud point.
-
Specify the maximum number of points to create for each filter point. Entering 0 will pick all points within the prescribed proximity.
