The places I've seen articles so far is "Electronics", February 4, 1988, on pages 69-70, and "Mini-Micro Systems", February 1988, pages 22-23. The first article offers more detail. I don't really want to rehash either article in full. The salient points (to me) about Dore' are:
(1) Toolkit approach. (2) Can render using vectors, hidden surface, or ray tracing. (3) Hierarchical, object oriented system. (4) Five object classes: (a) primitives (including points, curves, polygons, meshes, cubic solids (?!), and NURBS (non-uniform rational B-splines), (b) appearance attributes (material properties, inc. solid texture maps and environmental reflection maps), (c) geometric attributes (modeling matrices), (d) studio objects (camera, lights) (I like this term!), (e) organizational objects (hierarchy, and evidentally the ability to define function calls inside the environment which call routines in the application program. No idea how this works). (5) Quoted times: 0.1 second for vector, 10 seconds for hidden surface, 100 seconds ray-traced (I assume on the Titan. No idea what kind of scene complexity or resolution). (6) Written in C. (7) "Open" system - source code sold in hopes of selling Dore' on other systems.
The best part (for universities and research labs) is the price: $250 for a source code license - not sure what the cost is for source code maintenance (vs. $15000 for commercial users plus $5000/year after the first year). Per copy binary license is $200.
I am teaching the ray-tracing section of "A Consumer's and Developer's Guide to Image Synthesis" at SIGGRAPH this year, so definitely want to know more. I would also like more information just out of curiosity. So, you university people, please go out there and get one - seems like a real bargain. The contact info for Ardent is:

That's all, folks,
