Checking if a point is inside a polygon is not too slow (you have to check the horizontal line starting from the point and going left how many times intersects the polygon: odd -> inside, even -> outside. And with 10-20 points I think you can approximate the data pretty well. Hope this helps. -- Best regards, Szasz Pal ---------------- Space Software Studio http://www.spacesoftwarestudio.com -- Binary/unsupported file stripped by Ecartis -- -- Type: text/x-vcard -- File: space.vcf --------------------- To unsubscribe go to http://gameprogrammer.com/mailinglist.html
