Find midpoints of alphashape's defining spheres
2 views (last 30 days)
if i compute a 3d-alphashape on a pointcloud...is it possible to find the midpoints of those spheres, which are defining for this shape.
I mean, for each triangle of the triangulation of this alphashape it is definitive, that a sphere of radius alpha will not go through this triangle. So there may be an corresponding "extreme" sphere for each triangle, which just touches the sides of the triangle, but does not go through it.
I need the midpoints of those spheres.
