I've been trying to build up a texture library in order to texture map my levels. I brought my digital camera to the park here in Knoxville, and took some shots of the grass, some rocks by the river, the sky. They were nice but I needed a little more variety.

So I logged onto expedia and bought tw…

I finished coded and implementing the quad-tree data structure to handle my collision detection geometry. I figured that a quad-tree would do the trick because I see no reason to partition the geometry along the y axis. If my level geometry consists of several rooms above rooms, I don't think it …

In a recent entry I made some comments about Paul Nettle's collision detection article here on gamedev. You can find his article here:

General Collision Detection for Games Using Ellipsoids

I spent some time this weekend combing through my code to try to find my mistakes. I found them and fixed th…

I fixed the key repeat issue with my engine tonight. Before, I was relying on the operating system key repeat setting to implement movement. So when the player held down the 'W' key, for example, the engine would move forward a frame, pause, and then start smooth scrolling forward.

There were two …

If the rules of life were really like the game Oblivion I would have woke up this morning and thought...

"So that's how you do it. What once was a struggle has now become second nature. Please distribute attribute points."

I will add +3 to my Collision Detection skill please.

I finally finished the…

I have basic collision detection working now. I still need to make the routine recursive and add sliding. Geometry that can collide is now a derived zone class of the world object. Only zone geometry is considered for collision tests. Selectable items will be another derived class of the world …

Have you ever seen Quake 3 running at 11,520 x 3072 resolution? Well, here is your chance. It required 27 DLP projectors running at 1280x1024 each to do this:

...fun with printf and the ray equation.

It snowed here over the weekend, so I finally convinced myself to do some work on this project. I am about ready to code up the collision detection, and I need some level geometry in order to test.

Here is a quick pencil sketch I jotted out on graph paper. I ran the image through a filter after I …

I've noticed silhouette detection being used more commonly in next generation titles. Perfect Dark Zero uses silhouette detection as a special ability of one of the guns. Here is an example (and yes, this was my camera aimed at the television :P)


PERFECT DARK ZERO - XBOX 360

What is of particular i…
