Re: Functionality of Overlap setting in Refine Align

Clear, thanks. I'm afraid I'm having to visually align in MeshMixer, the noise in my photogrammetric model is evidently too high for CloudCompare tp see what to my eye looks clearly in common. It came sort of close, scale seemed about right, translation also, but rotation was off a good 20% on one a...

Re: Q: CC for aligning unordered scan data

Got it. So, if I'm following, the control points should be along all three axis and spread out as far as possible to avoid rotating around an axis or smaller region, yes?

Functionality of Overlap setting in Refine Align

I'm unclear how to use Overlap setting within the Refine Align tool. I see I'm not alone, this video at about 30:20 in poses a similar question, not clear how to think about what effect a low, mid, or high percentage overlap has when refining an already aligned pair of meshes or point clouds. I've s...

Q: CC for aligning unordered scan data

I've been experimenting with a workaround in CC to align scan data from a handheld scanner to a photogrammetry-derived mesh. It's straightforward setting control points, assigning the reference, and running the refined alignment tool afterward. I encountered an issue numerous times after a decent al...
