I filtered out all the leaves to only have the stems left to reconstruct. I will try to filter out less points on the stems to have a better basis for the mesh as you suggested. Thanks for your input!

Hi Daniel, Yes, I tried to invert them. But it just changed the stem part with the "good" normals to have the black ones and vice versa. For the poisson recon I could not see a difference. I also tried to use the "preferred orientation option" but could not figure out which setti...

Hi everyone, Thanks DaanS for the nice explanation! I tried to use the same way, with a few adjustments on my point cloud, where I want to reconstruct tree stems. To compute the normals I used: the quadratic model, octree 0.1 and knn 6. In the poisson tool window I selected octree depth 8 and in the...
