Ouch!!! That''s one expensive book $116 at amazon.com. I will most likely buy it because there are so few CSG books so every little bit helps.
I managed to buy it used at a University bookstore for probably half that. But I did buy it in 1993 or 1994, when it was probably easier to find. I''d check your local University library (if one is nearby) first, before buying it.

Right now, I''m looking over ACIS website, pretty impressive system. They use OpenGL for shading and interactivity. I will use Direct3D.
We use ACIS here. It is not cheap by any means. We''re talking $$$ similar to Quake II license fees ($100K). And we only have two developer seats, I think, and at most maybe 100 users. Price goes *way* up (think millions of $) if you have tons of users.
Its an ordeal just to get in the door with them.
Have you looked into using metaballs for booleans on solids? The Blender modeling system (available for free at www.blender.nl) is a good way to play with metaballs. The algorithm for implementing metaballs is fairly simple. You don''t get a hard corner between objects being booleaned----its rounded and smoothed. And maybe you can''t have objects that have sharp corners. But they are pretty cool. You can do union and difference booleans pretty easily using the metaball approach.

You mentioned that you wanted to change your job. Doing what? A game programmer or something else? Curious minds like to know
Actually, its a fair question (even though I said I did not change my company). Yes, I wanted to go to a game development company. I interviewed with a few---mostly phone interview because I got an offer after my first live interview and before any of the others went live. For 4 years now I''ve been working primarily on this NASA contract (NextGRADE) and it is mostly busy work. Add a dialog here, a menu there, occasionally (when we''re luck) go play with the big SGI system and VR display at Langley, every now and then add a new 3D feature. It isn''t really going anywhere fast, and I was stagnating. I had to get out of that. So I walked in with a resignation letter and they counteroffered with the IR&D that I''m doing now.

Oh, I just noticed that angry face on top of your post.
P.S. Is it ok if I shoot you some email sometimes?
I just like to play with the different images!
Sure Jerry, you can email me sometime. Although I don''t have time to just have long conversations by email. Usually, I can''t do more than one of these long answers a day!
