Finally a demo for all you guys who were fooled to buy a Dell (Highend CPU + crappy videocard).
This demo should run on pretty much every card out there, but may demand a little CPU power.

It's a cool particle system.
Never done anything with particles before, but it didn't take long to make it and add loads of features to it. Particles are pretty cool, they allow all kinds of funky effects and are easy to implement and quite easy to handle once implemented. This demo only shows off a few of the features I've implemented, but it has these adjustable parameters which may interest other coders out there:

A demo of the game engine I've been working on. It should run on the whole Radeon series card, Parhelia, GeForce 3 and GeForce 4.
It's a flyby demo, moving you around in a not too unfamilar environment for some of you FPS freaks out there.

Bumping this demo up again as I've finally got around to clean up the code and sort of finalized it. Source in now available for all you people that I know have been waiting, I apologize for all the delay. There aren't a whole lot of changes since last time, slightly tweaked lighting, the fogging I worked didn't make it into the demo either, it would be too much trouble to get a solid implementation on todays hardware with the method I tried.

This is a demo of a pretty realistic water surface. The waves are created dynamically by generating a texture with some perlin noise. The refraction is done by rendering the scene to a texture and then the wave texture is used to perturb the texture coordinates on a per pixel level in a fragment shader. Similarily for the reflections, except that they are rendered to the texture with y inverted. Finally, it's combining the refraction and reflection by interpolating between them depending on the view angle.

It'll only run on Radeon 8500 card right now.

Updated to run on drivers later than 6071. A driver bug was fixed that exposed a bug in this application, which I have now fixed. It won't run on older drivers anymore though.

My first Direct3D app.
This demo shows a keyframe animated character, anyone who have played the old classic game Bubble Bobble will recognice this as one of the cute little dragons from it. I've made it in Maya and a loader for .gof files you can export from maya is included. It has 17000+ polygons.
There is also code to help the serious lack of simple glVertex() calls for simple test stuff as you have in OpenGL.

This demo shows dynamic per-pixel lighting with shadows and proper shadow overlapping. The shadows are created by using the stencil buffer and Carmacks reversed algoritm.

This is a demo showing how to create a hot air effect with dependent texture reads. First the world is rendered to a texture, then to the screen. Then it creates a fire with a procedural texture. This fire texture is then used both as colors and as an offset of the texture coords for the texture I rendered to. The final result is an effect where it looks like the hot air around the fire refracts the light from the background.

Easy? Oh yes!

A cool little Winamp plugin. It uses dot3 bumpmapping to create a quite nice effect while moving to the music.
It supports fullscreen mode, selectable bumpmap and number of lights and other cool stuff
It should work with all cards on the market, but bumpmapping will of course only be enabled for cards supporting the recommended OpenGL extensions below.
