Please use the PDF format versions if possible, as these have the correct page layout. The Word format documents have been converted from another word processor, and the formatting will vary slightly depending on which version of Word is used to view them, the default paper size, page margins, the font in use, and so forth.
For an on-line technical writing sample, please see the plain English raytracing tutorial linked to inside my raytracing pages. I also recently wrote this Celtic knot tutorial for a quiet graphics Wiki. (Note that the tutorial may be moved to a subpage at some point without warning.) I also have some further (hidden) writing samples available if needed. Please contact me for the URLs.
If you want to learn more about how I apply my technical skills in my own time, why not look at my raytracing pages?
