I have polygonal surface representations of some neuroanatomical
structures and would like to write a program to render them as wireframes
with 3-d perspective clipping and hidden line removal. Does anyone on
the net have any c code available for donation to a good cause? The
original output format doesn't matter much--I can hack it to do the job
on our display here.
Thanks.

Sorry I couldn't reply by mail... If you want some good informat on 3d wireframe and/or filled image projection and manipulation, I highly recommend 2 books by Lee Adams: I believe they are called Animation and Simulation in Graphics and Modeling, Rendering and ???? In graphics. You should be able to find them at any B. Dalton's or Software etc. They are loaded with formulas and source code in BASIC so that it can be easily implemented into any other language. The books explain simply and in human terms how to display 3D objects, to rotate and how to project them onto the screen. Animation techniques, dithering and halftone, and hidden surface removal are covered in detail with source and formulas to help. Jeff Bakke NU113738@NDSUVM1.BITNET
