They are indeed displayed one pixel off.
I think this is normal OpenGL rasterization. The points rasterize at the actual location, but I think lines and polygon edges have some sort of not-at-the-point-or-edge thing going that means they never rasterize ON one on of the two points that make up the line. I can't find the reference to this right now, maybe someone else can give you the cite. -- Chris 'Xenon' Hanson, omo sanza lettere. xe...@alphapixel.com http://www.alphapixel.com/ Digital Imaging.
