Today, OpenGL has updated to 4.1 and 3.3.
It can express high-quality graphics. But recently, it lost GLU functions. So tessellation method can't be used.
Therefore, it has been difficult to make polygonfont .
Now I made a method that tessellates from closed paths into triangles .
It also have a method that creates closed paths of outline fonts .
This code is not excellent and not improved so much, but if there is someone who wants to create polygonfont, please use this freely.
Thank you .
