Re: I can't make an octree with more than one subdivision

AHA! I love it, thanks!!! Now for my next ignorant question...is there a way to output this octree/segmentation to a file to use in another code? That is, can I save the hierarchy of the tree, the cubes axes, and the points that are in each cube?

I can't make an octree with more than one subdivision

I have a point cloud with 100,000 points, and when I run Edit --> Octree --> Compute, I always end up with a single 8-box structure around my cloud. It sounds like I can recursively make finer resolution, from looking at web documents, however I can't see how to do that from within the GUI. I'm usin...

Re: how to fit a single shape to a point cloud

Thanks Daniel. Regrettably, the RANSAC fitting hits a 'segmentation failed' when I go that high. I have 185,717 points. However, tinkering with that value I did find that I could get just one cylinder. Thank you! I am thinking that it might a useful upgrade feature to allow the user to specify exact...

how to fit a single shape to a point cloud

Daniel (et al.), I love your software!!! I am trying to fit a single cylinder to a point cloud, to robustly measure its orientation. However when I use the RANSAC shape detection, it seems to replace the point cloud with the union of many cylinders to completely reproduce the entire cloud. Perhaps t...
