Index overflow

[Kjellis85]

I am encountering Index overflow on a 582M poly dense cloud, processed at Ultra High. During meshing the index overflow happens after 24 minutes. Is this a RAM limitation or a bug?

Hello Erik,

This dense cloud seems to be too large for Poisson mesh reconstruction. If you need to continue working with dense cloud based mesh generation - then I can only suggest to process the scene in blocks.

Alternative way is building mesh from the depth maps, but this approach is not applicable, if you have imported the dense cloud from the external source.

The dense cloud is not external, I have depth maps. I did manage to get a result when I classified the point cloud by confidence and used only points with above a certain threshold to generate mesh. Unfortunately this mesh was completely useless and I did not save it. I will however try using the depthmaps instead.

You can re-use the depth maps to save the processing time, when building the mesh from depth maps source.
