Succesful install, but functions not working properly

[tverbrug]

Hello,

I was able to succesfully install your library using the pip method on Ubuntu 18.04. I am able to import the module into python and I can run the test_examples.py script. However, when I look at the results, I see that the sampling functions do not work. Both pcu.sample_mesh_random() and pcu.sample_mesh_poisson_disk() just result in the original vertices and faces. There are no error or warning messages.

Hey, thanks for reporting this!

The issue is that sample_mesh_poisson_disk downsamples a mesh using Poisson Disk sampling. Since you specify 100 times the number of vertices, you're going to get the whole mesh. If you have a mesh, you first need to upsample it. The new version of this library will include an upsample_mesh function which upsamples a mesh using subdivision.

This is now fixed. sample_mesh_poisson_disk generates Poisson disk samples on the mesh. There's a new parameter to generate a given number of samples, or you can use the radius.

I also fixed the random mesh sampling function sample_mesh_random to properly upsample.
