Hi,
I have a 3D object (as shown in figure) defined entirely by x,y,z coordinates. Below shows the plot using scatter3().
I do not have the triangulation information.
My ultimate goal is to convert it to an .*stl file. How do I mesh it? delaunay(x,y,z) is giving something like this which is not correct.
Do I need some kind of algorithm to mesh it ?
Or else can I convert the coordinates to a .ply file to use meshlab to mesh it ? I don't know how to convert. Since this is a closed figure meshgrid() etc. are not working.
Thank you for the help.

pc = pointCloud( [x(:), y(:), z(:)] );
pcwrite(pc, 'OutputFileName.ply');
This requires the Computer Vision Toolbox.
