OK no offense but I busted a seam laughing over this one. Remember your basic highschool math:
Polygon: a closed curve with straight sides
Translation: a bunch of little lines that all touch each other
Ex: squares, triangles, pentagons, and anything else that doesn't have holes.
A curve doesnt, by definition, have straight edges =).
Any 2 dimensional figure with 3 or more straight edges is a polygon. When moving into 3 dimensions, the figure must be coplanar.
Z.
*AHEM*
First, a curve CAN be a straight segment; ever take calculus? Or algebra II? or geometry? or 1st grade math? (j/k on the last one)
Second, it MUST BE CLOSED. All segments must contact exactly two others on their endpoints. Crossing lines and lines that don't touch disqualify a curve from being a polygon.
My bad. No, ive never taken Calculus =(, and didnt learn a thing in Algebra II (knew most every bit of it already...). I bow to your superior knowledge =).
Z.
*cough* ...
Since we're in a game programming forum here the definition of a polygon would be:
A class containing at least:
- 3 corner points (or links to them) that are stored in a certain direction (cw or ccw)
- Can also support a color
- And/or several maps (like a texture)
- Other Properties, depending on how you need it (ie. if this polygon is collidable, transparent, etc.)

h0h0h0, just trying that out, i dunno what the hell it does though, certainly didnt improve that code!
thanx fo rthe polygon help :D
