Ed: Here's some more info that I got from Colin Irwin on the GRAPHDEV forum: >>>The shuttle was rendered in Autodesk 3DS using the technique first suggested by Yoon Kit Yong of Imperial College: "If you happen to have 3D Studio, bump files can be generated by 1. Making all materials to self illum, White. 2. Define camera ranges for foreground and background 3. Define atmosphere distance cue, 0% -> 100% 4. Remove ALL light sources. Ambience to 255. 5. Render, no dithering, Phong/Metal. 6. Output to Mono TIFF Uncompressed. Try to avoid sudden changes in levels. This tends to leave outline marks and alot of further distortion on the edges." This gives you an output image which is smoothly shaded from back(black) to front(white). You can then plug this into my program which analyses the picture to look for level changes implied by changes in brightness of the source image. Although the image looks very smooth it is still banded, but the colour wallpaper and the smaller increments between bands fools you into thinking it is a continuously smooth image. I recently licensed a very large (4800×3600) SIRDS to poster manufacturers Athena International. The subject is a VW Beetle with a couple of Yin Yangs and some text thrown in for good luck. The final print dimensions are 890mmx590mm and the test print I received last week looks excellent. Once again, thanks for your comments. Col<<< Some Ed Kellerman SIRDS uploaded here would be cool hint, hint <g>. I just got that remote control watch I talked to you about. Performs perfectly at 20'! Besides operating my vcr, tv's and cable boxes it even tells time <g>. Bob
