>>clean RDS… Hey David the Graphics Wonder, All of the images I've done with the random dots appear to have steps or levels along their depth. Is that what you mean by "sliced"? I've noticed a similar effect on some commercial images. Solid objects remain solid, however. The images done with a GIF background look better. One thing to watch out for: when you diverge your eyes, if you diverge TOO far and lock onto the next strip, objects in the foreground will be broken into pieces. (Another thing to try: crossed eyes give a depth-inverted image). A mathematics wizard I know is looking at the algorithms and is writing his own version – I'm waiting to see what he says about the artifacts and if he finds any limitations in the code. One consideration: I believe RDSGEN wants a specially coded image, where the red values encode the coarse resolution and the green values encode the fine resolution. The grey image may at best be a poor compromise. BTW. I get considerably less "step artifacting" when I render the source image using a custom greyscale palette. Note again that the TGA option may NOT be the best one to use. With TGAs, I think I had to both mirror the geometry before rendering AND specify depth-inversion in RDSGEN. I did think about uploading some stuff, however 1) the libraries appear to be untouchable just now, and 2) I haven't had much time to play yet and don't have anything yet that I'm especially proud of. (Some one named Stinnett set a new standard for excellence around here! <g>) J K J PS: another thing I want to do is make an RDS animation (perhaps calling RDSGEN from video post).
