compress PTX file

Post by phillhend »

I have Polyworks ver. 12 and with it only the IMinspect and IMview licenses. Using just IMinspect can I compress/ unify and reduce the amount of points in the scanworld?

Right click on the dataset/s, Edit -> Subsample
You can apply the subsample to either the objects in the feature tree or to selected points and decimate either by uniform spacing or by curvature.
Remember that once you have the PTX in ImInspect it is no longer a PTX scan (ie. gridded data) but if you had your import settings for max angle and max distance set correctly then you will have point normals instead of just dumb xyz points.

How do you know what the "correct settings" are for max angle and max distance?
Are there defaults, like 200m (if max range on scanner is 150M) and max angle of 90, 180, 360?
