I'm writing a simple flight simulator using a stereoscopic 3D
display. I'm looking for a text on flight simulation, the only one
I know of is:
Garrison, Paul
Microcomputers and Aviation
New York: Wiley Press, c1985
UCSD doesn't have the book; is it a good text? Know of any others?
I've currently implemented a simple shaded polygon animation system
with depth sorting, backface culling, and one point source illumination.
What I need to research is efficient database manipulation of the world to be
simulated. I can easily implement this system by simply checking
all of the objects in the world, but this is very inefficient. Any
clues? Reference material? Examples?
I could also use some advice on fast hidden surface removal techniques.
Any input on high-speed 3D animation would be much appreciated.
Thanks,
John Schultz

Know of any others? Well, this *may* help. There is a book out there by Bruce Artwick, who developed the famous SubLogic "Flight Simulator" including the original graphics routines. Unfortunately, I do not know the name of the book or the publisher, as it was one of those books that I was going to buy, but did not have the money to spend or the time to invest reading it (they are sooo many good books out there to read! ;-) I would say that this is a good book to read. Does anyone else have a full reference? If nothing else, you could probably look in the "Books in Print" catalog under the author's name, or ask the ordering department of a large bookstore to help.

If your plane will not interract with moving objects, I suggest you drop the sorting to get hidden surface removal. A good article is "Near real-time shaded display of rigid objects", by Fuchs, Abram, and Grant. SIGGRAPH 1983 Conference proceedings (Computer Graphics 17, No. 3. July 1983 pp. 65-72) It describes a BSP (Binary Space Partitioning) scheme where a one-time process is used on the environment you want to fly through. Thereafter you can draw the scene from any position/viewing direction WITHOUT sorting (by walking a tree structure). This will not work for objects which can move, like other planes. I think you could use this for the "earth" if you can assume that the moving objects will not be "hiding" behind parts of the terrain. I am thinking of other planes which will not be below ground level, hiding behind trees, etc. You could use BSP to draw the terrain, and any other technique for the other objects as a second step. As I remember, the article talks about trying to overcome the problem of moving objects. Does anyone know of a later paper that addressed this? - mark

I haven't referred to the book in quite a while, so I can't really remember what I thought about it, but I'm sure that it will help in a number of areas.

It covers the basic 3D matrix math (including the little known Quaternions!), talks about using fixed point, etc, but I am looking for database information, polygon clipping/elimination, etc. I've got a little "remote control airplane" simulator up and running using shaded polygons, which runs quite fast. I'm looking for ways to run faster, especially how to process the "terrain" without examining/processing _every_ object. Thanks, John Schultz

It has lots of neat stuff. I have the first edition from 1984. I believe that there is a new edition out. In any case it's called: _Applied Concepts in Microcomputer Graphics_ by Bruce A Artwick ISBN 0-13-039322-3 T385.A77 1984 Prentice Hall It doesn't have a section on "airplane physics" (at least I can't find it :-) so I don't think it will help much on that. It should be able to help on hidden surface removal and other animation type problems. I personally like the book for it's discussion of certain aspects of computational geometry. --Bill Davidson -- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ....!{ucsd|sdcsvax}!celerity!billd
