3D triangulated model

Post by Hajos »

Hello All. Please, how can I make a 3D triangulation model? I have a point cloud from scanning the tunnel and I need to make it a 3D triangulation model. I tried it through poissonRecon. But I was not satisfied with the result. Because if I compared the network with the points I created it the deviations were somewhere over 3 cm. Maybe I made a mistake somewhere in normalization or in defining parameters, but I tried different variants and the result was always the same. I need to make a 3D model so that my points from the scan are the "corners" of the triangles. So if I compare the points with the network, let the deviations be minimal. Can you please achieve this nicely? I will be very grateful for any help.

Have you increased the octree level/depth when reconstructing with Poisson? Because the lower it is, and the more 'approximate' the result will be (as you basically have less and larger triangles).

Hello Daniel,
I've figured it out. I have the best solution when I used triangulated surface (normals) and I increased the weight of the points in Poisson. Have a nice day :)
