I manually segmented some trees and want to use to cross section tool to generate some envelopes as its described in the wiki here: https://www.cloudcompare.org/doc/wiki/i ... ss_Section. My goal is to get convex hulls.
What I understood is that the concave hull algorithm starts as a convex hull and then starts splitting. When i hover over the 'max edge length' parameter field, a small tool tips pops up which is saying that when the value is 0, a convex hull is generated. In the wiki this is not explicitly stated.
When I run the tool with the value 0, concave hulls a generated, which makes sense for the value 0 if it were not special.
So my questions is, whether the generation of the concave hull is intended or whether the convex hull should be generated. For my case i simply use a high enough value for the 'max edge length' parameter as a workaround, but since the algorithm starts at a convex hull, it would be nice to be able to simply use that starting hull. I added a screenshot for your understanding.
Thank you very much for your software! :)
