I recently studied an episode of Federico's tutorial and it was fantastic!

I made a little modification to his patch by replacing jit.bfg with jit.gl.model so that I could transform the 3D model into a point cloud.

But the result is not very satisfactory, because the point cloud splits into some rectangles according to the position of the vertices of the 3D model.

I want to make the point cloud shape smoother, and I have tried many methods without getting the desired result. Do you have any good suggestions?

You can create a point cloud generating n points randomly distributed on the surface of each triangle of the mesh. 

The attached patch generates a fixed number of points per triangle.

A possible improvement could be to take into account the area of each triangle and generate a proportional amount of points randomly distributed on its surface, to get roughly the same coverage everywhere.

hope this helps, cheers!

Your patch is so amazing, it's exactly the effect I wanted. Your approach is a direction I never thought of and I'm inspired by it. I hope more people see this post, it's a fantastic technique.

yes, i saw it yesterday and it brought tears to my eyes(but wanted to wait til Shihua saw it before i responded: Thank You, Shihua, for starting the thread).

Thank You from me, too, Matteo, (and also for your recent oscilloscope tutorial). 🍶❤️‍🔥

I haven't asked for help on this forum for a long time, and this time the problem was so hard to solve that I thought no one would reply.

Thanks to Matteo for his help, he is one of the most powerful jitter users I know, and it made me realize that communicating here is still a great way to get everyone ahead.

Hope we can realize our ideas!
