CloudCompare forum

Hi there! I would like to generate mathematical art using CloudCompare. Can I send in an image file, for example black and white, and generate a cloud heightmap, preferably with a floor plane so that a poisson algo can generate a mesh from it? Thanks!

There are a lot of processes for point cloud simplifications. http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.10.9640&rep=rep1&type=pdf What is currently the best, state of the art, for those algorythms? It's a Spanish team from 2003, so there must by many more enhancements and adva...

this is interesting: Boissonnat and Cazals [8] introduce a coarse-to-fine point cloud simplification approach. Their algorithm takes a random initial subset of the input point cloud and uses its 3D Delaunay triangulation to define a signed distance function over the set. This implicit function is th...

Meshlab has quadratic edge decimation which is very cool and free and some other decimation and point cloud filters, my fave is 3dsmax 2016 planar simplification.

Hey i'm near Gre too. General recommendation for an algorythm that is very useful for houses and any objects that have flat parts. Super efficient easy algorythm... sample grids or spheres comprising 10-50 vertices, measure if they are on the same plane, if they are almost exactly on the same plane,...

Hi Daniel, i found that Mehlab has selection of vertices by full mathematical formuli so spheres and things, perhaps you can steel their code for that, don't know if it's ok to steel from other open source projects but steeling is fine if it's in secret. see ya.

Hi, The option Edit>Colors>Convert to Scalar Field is greyed out and not selectable, it's for a RGB scalar field that was generated using Tools>Sandbox>Distance Map...

What is missing from the RGB distance map to let it be selectable by RGB values?

I am rushing with some work and i want to write a program that deletes all points of cloud compare within a spherical radius, same as cross section, except that all points within a sphere are segmented to another group. It would be a good design tool for people that work with vases and similar, to b...

Hi all, thanks for all the incredible work invested in CloudCompare. I was suprised that the boolean operations code is only for mesh!!! It's a lot easier to do boolean when there are no triangles to thing about, that is the entire difficulty of CSG for spheres and simple objects. I expect that a CS...

Do the points get deleted based on distance? Do two close points get averaged?
