I know I should just go look it up, but how hard is it to decompose a
polygon into triangles?

Ah, I should go fire up LDScript, just for the polygons...

Steve, you gave me an idea, hehe!

Here's my first pre-embryo of an LDDP plugin:
http://home.swipnet.se/simlego/ldraw/plug_lds.zip
So far, it is anything but impressive. It can only handle the LDS LINE
command, and without any error check at all.

Just copy the DLL into the Plugins folder
Then run the LDDP and enter some lines in a new document:
LINE [color]
-20 0 0
20 0 0
20 0 20
0 0 30
-20 0 20
-20 0 0
LINE END
Colorful, isn't it? ;)
Run the LDS Plugin and voila! You have a neat polygon.

But you want a filled polygon if I get you right?
So, how do you want the input syntax and, more important, the output?
Should the program look for the centre of the polygon and make pieslices
from it or just draw triangles from existing points?
