Leaf triangulation
Triangulation is the process where a (ordered) set of triangles is generated out of a (unordered) set of points. The result is a set of triangles, now called faces, that can be directly drawn.
Let's see the following set of 2D point:text/html2026-03-27T16:46:54+00:00Tim (Tim@undisclosed.example.com)Overload operator - [Overloaded operators]

Overload operator
Operators can be overloaded in XL by declaring the method operator$NAME_OF_OPERATOR(var , var ){}.
The list of operators in groimp is available at: xl specification.
