I know others have posted such requests in the past, now it is my turn. I have the ray tracer that was posted to the net and is in the archives. While it does indeed work, I'd like somthing more versatile and perhaps faster. I would also like any pointers to sources I could study for doing my own implementation/modifications. Please reply via E-Mail. Thanks in advance. Sid --- Sid Grange ihnp4!chinet!sid Safe sex is okay, just don't do it with a time lock vault at closing time.

One of the finest ray tracers available anywhere is available free from the U.S.Army. It is part of the "BRL CAD Package" which also includes some graphics editors and other miscellaneous stuff for dealing with frame buffers and such. To get it: Send 1. Enough mag tape for 15MBytes of data. For 9-track mag tape specify density. SGI or Sun streamer cartridges can also be done. Specify blocksize and whether you want TAR or CPIO. 2. A letter indicating: a. Who you are. b. What the BRL CAD package will be used for c. What equipment you plan on using d. Agreement with the following condition. 1. That you will not pass the source code to third parties. Send them to BRL. 2. BRL should be credited should the software be used in a product or written about in a publication. 3. BRL assumes no responsibility for the code. No Warrenty is expressed or implied. 4. If you find any bugs or problems, report them back to BRL. ---Aside from a former BRL employee: Mostly, all the above requirements are done to protect the ability of BRL to give this code away with the absolute minimum of government hassle. Especially important is that they know who gets the code. This allows them to demonstrate how much of the technology developped by the lab is used by people other than the Army itself, and allows them the justification to continue developing fine software such as this. It's pretty free other than that. Anything you make out of the package (images, geometry database files) are yours. ------ Mail all this to: Director Ballistic Research Laboratory ATTN: SLCBR-SE-C/M. Muuss APG, MD 21005-5066 If you are from outside the US, things have one more problem. As with all government papers shipped to outside-US sites, you have to forward the request through your country's embassy in Washington. Have the Ambassidor forward the request through official channels to Deputy Chief of Staff for Intelligence Army Headquarters ATTN: DAM-CIT Washington, DC 20310 ------- Also, there is a mailing list maintained at BRL for discussion of new features and problems with the package. -Ron

I am also interested in obtaining ray-tracing software. Currently I have a ray-tracing package from the amiga that I have reconverted to VAX/VMS. It has pebbles and cylinders in it that I can't seem to figure out how to use. I would be interested in obtaining ANY graphics software sourcecode. +-----------------------------------------------------------------------------+ | | Dave E Martin | DISCLAIMER: Been Cancelled | | /\ | "...between the streets of | $ opinion/mine/noUinTech | | / \ . /\ | Dallas, and the beaches of |----------------------------| | / \/ \/\/ \ | Miami ...
