Hello,

I would like to create a mash from a point cloud that is in LAS format. When I click the "PoissionRecon" function, I get the error message "Cloud must have nomrals!".
Can you help me where exactly the problem is and what I have to do so that I can create a mesh?

Thank you very much in advance.

You have to compute the normals first: see https://www.cloudcompare.org/doc/wiki/i ... %5CCompute

Mind that the normals orientation is very important for the Poisson Reconstruction algorithm.
