I am the graduate student at the Computer Graphics Research Group at The Ohio State University in overall charge of the undergraduate amiga graphics environment. Our vax has recently gone to 4.3 BSD and postnews doesn't work, thats why we've been silent lo these many weeks. To answer some of the recent questions on the net, we are doing both instruction and development. We have been a beta site for C-A since last Feburary. We presently have 15 amigas we use for instruction of undergraduates in 2 and 3 dimensional graphics. There is a series of 3 courses offered. We use Aegis and D-paint for the 2-d work and local software (eye) for the 3-d stuff. The main thrust of the undergraduate program is to bring powerful 2/3-d computer graphics to the undergraduate level. The classes are studio oriented, and in the higher levels the students do some C and create 3-d animations. The development work we are doing is limited to 3-dimensional graphics/animation. Presently we are using a 3-d package written here at Computer Graphics Research called eye. Eye is a simple program that allows full eye point center of interest and object manipulation; translation, scale, rotation, hierarchial attachment of components blah blah blah. Right now eye only has vector rendering capabilities with trivial hidden line removal. Eye is is very similar to the rendering software running on the Unix systems The next level of development will include the amigas in the overall software development scheme here at CGRG called the Animation Production Environment or Ape (he he). This environment will allow the amigas to share data (bitmaps, 3-d data bases etc) with all of the other systems we have: Vax780, sun2's and 3's, Convex C1, Ridge etc...... Software under ape will be device independent at the application level and all aplications will have a similar user interface. All of the software staff here have their own amigas at home. What this means for the amigas is they will have a fully integrated 3-d environment, with lots of components running concurrently. The software will have the same functionality of the stuff running on the big machines. There will be a full size background raster display window. The 3-d images will be rendered to disk in 12 bit virtual with a variety of display options as low-res, hi-res hi-lace, ham. You could then save the image as a IFF file, or conversly, load a IFF image and render on top of it. The raster renderer will be a fast scanline algorithm with probably no anti-aliasing for non ham images. There will be a smaller vector playback window to view in near real time a precalculated animation segment. Eye will reside in another window. To manipulate objects you can either type in the commands into a parser like it works now, or use the mouse to manipulate object attribute gadgets. Included with the package will be a program to interactivly generate 3-d data. An interactive keyframing program and lots of specialized software for doing miscelaneous 3-d graphics. Many of the components of this system are already here. The scanline algorithm is running on the Convex and needs ported to the amiga. We already have eye, and work has started on the window interface. I imagine that most of this will be running by this summer. However at this point the software will not be released to the general public. There is no system to activly support the software offsite, and the documentation is not that good. The first versions of the system will go here and to other education institutions. Akron University, Miami University (of Ohio), Moore College of Art and other schools are purchasing amigas and peripherals according to our recommendations, and they are in line to get software. If you are from a university or some other kind of school I could probably send you binary copies when its ready. Hardware wise all of the machines have 1.5 meg of memory, there is a single frame 3/4" video deck to do single frame animation, (we use a !ack! zenith pc for the controller) a video digitizer, and we are evaluating the Ameristar ether card/software as a possible means to network all of the machines to a vax 750 in the same building. Anyway we hope to have an article in a future issue of amiga world which will have the low down on whats happening here at Ohio State. If there are any other specific questions I'll try to answer them.
