Can this be done: Create a 3-D model in Sculpt 3-D, paint/render it with Spectrum, then animate the frames? Is there any software pacakge/integration of packages, that can do this for me using Spectrum? I do want the advantage of all those colors on the screen at once... Thanks gunnar alexd@milton.u.washington.edu

There's a player on atari.archive called ANISPEC and a couple of animations: WALL, 3D-512 I think, and another one. Unispec can be bought for under $30 mail order I think. There's also a program, shareware or commercial, not PD, that lets you do 3D modeling in 512 colors, but I don't remember its name. I have a sample output pic. Leave me some e-mail if you're interested and I'll post it on atari.archive. >Thanks > >gunnar >alexd@milton.u.washington.edu -- Ed Krimen ............................................... ||| Video Production Major, California State University, Chico ||| INTERNET: ekrimen@ecst.csuchico.edu FREENET: al661 / | \ SysOp, Fuji BBS: 916-894-1261 FIDONET: 1:119/4.0

First of all, to get animation using Spectrum 512, there is a program called Unispec, which is actually an upgrade module to Spectrum, which turns it into a desk accessory and adds many new features (including animation.) The new additions alone merit recommendation for anyone who uses Spectrum, such as better anti-alised(sp) functions, and an improved dithered blur, just to name a scad few. As for rendering it in spectrum, there is a painful way, and some other not so painful ways... First of all, you could always just use Cad 3-D (I believe you are referring to CyberSculpt, if not, then the rest of these techniques do not apply...) and do a straight degas import into Spectrum, frame by frame (also, Cyber Control, an animation scripting language, is recommended for this) and tweak the colors using spectrums global color commands. There is also a program from the magazine STart, called RezRender. This program can use Cad 3-D objects, and raytrace them using various styles (flat polygons, gourad shading, off the top of my head), BUT can only render in 16 shades (yes you can make 16 psuedo-shades, on most colors except some such as grey). It does, however have many excellent features like shadowing, chekerboard plane backgrounds, gradient backgrounds, and limited animation. I believe this can be founds in the February 1989 or 1990 issue of STart. Another program, called GFA Raytrace (which is VERY hard to find, but one source would be on the British-mag ST Format, not sure which issue) which will raytrace objects in full, glorious 512 colors, BUT it is not compatible with Spectrum 512, and the tools are quite limited. Also, there is news of a new program from a company called Lexicorp, which is creating a 3-D rendering system far superior to the Cyber series. In summary, it is a bit of a pain to do 3-D animation in Spectrum. Like any system, you need gobs of memory (even at 8 Megs you run out of room!), and things like an accelerator are VERY handy to have (it took me at least 12 hours to render 16 frames of a rotating object on a stock 1040 using RezRender).

I have no idea how they were done. The viewing program I posted to atari.archive (showspec.arc, I think I called it) has an option to show these animations. They appear to be mulitple spectrum pics with a sequencing file. If you do not have these animations, and they are not on atari.archive somewhere, let me know and I will arc and post them. These are two of the first demo's I ever got. Remember "Shiny Bubbles"? That one sold a lot of Atari's! The two spectrum animations are of the highest quality. -- ---------------------------------+------------------------------------- Mickey R. Boyd | "Kirk to Enterprise.
