I always believe that CC is doing very well in meshing but it always astonished me when sometimes CC fails to mesh simple and dense pointscloud.
I found that CC can mesh some of pointscloud perfectly while if the same pointscloud is rotated 90 deg around X-axis, CC fails
please check the attached example
Pointscloud rotaion affects meshing function of CC
Re: Pointscloud rotaion affects meshing function of CC
Are you referring to the Delaunay 2D (XY plane) triangulation method?
Because this method is supposed to be applied on a 2.5D cloud more or less parallel to the XY plane (so if you rotate your cloud about X, it won't be parallel anymore).
The other version (best fitting plane) fits a plane on the cloud before projecting the points on it. It's probably a better idea to use this one if you don't want to make your cloud parallel to the (XY) plane.
