Hi again Sebastien,

I keep getting 14 segments no matter what values the parameters have.

I'll try that value and come back with the results.

Hi Sebastien,

I tried using a modified demo in order to get the segments in different
meshes. I'm having success in getting the segmented meshes but
segmentation doesn't seem to change with any of the parameters.

Could you specify what value of smoothing lambda you used?

The default in the demo: 0.26

Sebastien.

    I tried using the polyhedron demo on the elephant model, selecting 6
    clusters and got something that is similar to the first image in the
    documentation. What did you try?

    Sebastien.

        Hi,

        Lately I've been working with CGAL's mesh segmentation
        functionalities
        and I'm having some problems achieving different segmentations
        through
        number_of_clusters and smoothing_lambda parameters.

        I'm using your "elephant.off" mesh as an example, and as I try
        to get
        the results you expose in your documentation for Surface Mesh
        Segmentation, I'm not able to get the same kind of segmentation.

        Even though I change the values of the parameters, I still get
        the same
        segmentation in every iteration.

        Could I get a hint of what I'm doing wrong?

        Regards,

        Pablo Sánchez
