Latest revision as of 00:41, 2 January 2011
I've written a number of articles for Game Developer Magazine over the years, and this is the place where you'll find the ones that don't get their own page.
All of these articles are in PDF format, for better or for worse.
I will try to get newer versions of the PDFs up at some point, since these have some font problems.
todo: lots more work to do on this page
Perspective Texture Mapping
This is my epic perspective texture mapping series. I guess it's a bit out of date now that 3D hardware is everywhere, but I think the discrete math in the articles is still very interesting, and I'm still a stickler for fill conventions and resampling rules. I still don't know of any hardware that does their fill conventions exactly right, especially given the extra information in the gradients.txt file in the sample code, and the fact that there's a bug even in that analysis having to do with exact perspective gradients (hint: a perspective warp can change the rounding modifier inside the triangle).

Compilers
These two articles aren't really reviews, even though I discuss the results of using a number of different Macintosh and PC compilers. In reality, they're tutorials on how compilers [fail to] optimize your code, and what you can do about it.

Memory Bandwidth
This article discusses how the access pattern your application uses can have a decided affect on its performance.
- Memory Miscellanea - Oct/Nov 95
Floating Point
To cover some of the wacky floating point tricks the perspective texture mapping articles use, I needed to discuss the floating point unit in some detail.

My very first article for Game Developer. You've gotta love that screenshot of WinDoom running on top of Excel. - Changing The Rules For Transparent BLTs - Feb 95
This was the first article for my column.
