nPoly / vector based FlooFill ? How or where?

Hi All,

I want to create a 'lasso selection tool' much like in photoshop.

So I have a list with n-amount of 2d points that make up for a closed n-sided polygon. I want to draw this shape to create a mask-image, but the shape has to be FILLED as well!

Drawing the shape is easy, but the filling is where I hit a brick wall. I can't use any pixel-based floodfills, because I have no idea what my shape 'looks like'. And it's lines could be crossing and intersecting, etc.

I've seen one BMax sample that does it, but it uses some function _Max2Ddriver.DrawPoly() not available in BB ( http://www.blitzbasic.com/codearcs/codearcs.php?code=1664 ).

I googled till me eyes were bleeding, but didn't find anything. Does anyone have any pointers, links or ideas?

Thanks,
Danny.

Have a look at this tesselate function.

It's primarily for 3d so you'll obviously have to have your own 2d polygon function to fill each one. It should point you in the right direction though.
