However I just noticed a problem. With the attached dataset (close to a
octaedron) I get 13 lines/angle one close to 180° why's that?
Here's the output:
Creating delaunay triangulation... done.
There are 13 line cells.
Computing angles...
179.929; 89.9738; 90.018; 90.2824; 89.7877; 90.0241; 89.9026; 89.9882; 90.0273; 90.0071; 90.001; 89.9956; 89.992;
Thanks,
Lynx
