Method 1: (The fan)
- You have a set of n points. Let's call them p1, p2, ... pn
- Make a triangle with {p1, p2, p3}
- Make a triangle with {p1, p3, p4}
- Repeat until you {p1, pn-1, pn}
Method 2: (The potato-chip)
- You have a set of n points. Let's call them p1, p2, ... pn
- Find the average of your points . This is the center of your shape.
Let's call it C
- Make a triangle with {C, p1, p2 }
- Make a triangle with {C, p2, p3 }
- repeat until you hit {C, pn-1, pn }
- Make a last triangle with { C, pn, p1}
This works with 2D as well as 3D points.
This shouldn't be too hard to script or program.
