Holes

[Socke81]

Hello, it's me again. ;P
Could you also implement holes? I'm currently trying to read .frag files and am using parts of your code for triangulation.

Very strange format. As with the other formats, there are vertices and indices to create the polygons. But there are also additional indices for holes. For example, you have a wall and you have indeces with which you create holes for the windows.
Would that be something you'd be interested in?

Hi. It’s challenging. I’m not planning to implement it. One trick is to convert a polygon with holes into a single polygon. That is, the outer polygon connects from one point to a point on the inner hole, traverses the hole, and then returns the same way. As long as the polygon doesn’t self-intersect, you can use my routine afterwards.
