produce mesh from pointcloud

[matecno]

Hi

I am new to this software, but everytime I try to generate a mesh out of my point cloud for the artifact it appears as if it is covered with nylon and messes up the texture (I attached a screenshot)! Any ideas whats going on?

P.S. I cleaned the model manually, but if there is a better way of doing it (I dont know the roughness method well), please share

Thanks

I can't see the screenshot.

I assume you are referring to the Poisson Reconstruction tool? If yes have you read the samll text about the 'density' scalar field that can be generated and how to use it to filter the 'bubble' parts of the mesh? (see more information here: http://www.cloudcompare.org/doc/wiki/in ... n_(plugin)

Hello Daniel

Yes I read it. But not sure what causes this. From your experience, what could be causing this? I cannot attach photos, but in the following link, you can access this image:

Hum, are you sure you are using the PoissonRecon plugin?! Isn't it the 'Delaunay' mesh generation tool that produces this kind of result?

If it is Delaunay, then this effect is simply due to the fact that by default the Delaunay algorithm triangulates the convex hull of the points. To remove the big triangles on the border, you simply have to set a 'max edge length' (the only parameter of the algorithm) different than 0 (and not too small in order to keep the right triangles).
