| | | | (...) Sorry, long quads is really what I meant by a line. So, that's exactly what the program does. I should have an update out later today or tomorrow that combines pixels vertically as well. Thanks, Scott (17 years ago, 24-Jul-07, to lugnet.cad)

| | | | (...) Keep in mind that doing it both ways is probably a lot more difficult than just doing it one way. For example, if you have a 1-pixel thick plus sign, you need at least 3 quads (to avoid overlap), and your algorithm needs to deal nicely with (...) (17 years ago, 24-Jul-07, to lugnet.cad)

| | | | (...) If you can work out regions of identical colour I believe there is a theory that says you can fill it with no more than 2N (where N is the number of corners) triangles. This is probably a good way of doing it for complex shapes. If I ever get (...) (17 years ago, 25-Jul-07, to lugnet.cad)

| | | | | Sorry that it has taken me so long. In fact, I am still working on creating quadrilaterals and triangles to fill the largest spaces possible. My main hang-ups are: reducing processing time a working point-in-polygon test I have found two different (...) (17 years ago, 26-Jul-07, to lugnet.cad)
