Image Description, by P Danhiez

This is a shot of my first (personal) game : ZooChess. I've writen it in my spare time (6 month), and all the code is in C++ using OpenGL. A friend designed all the chess-pieces.

The engine (called ZooEngine) has some features like bump mapping, water effect, etc.. I draws polygons (45.000 for ZooChess) and the GUI is totally in 3D. Stop ; this is not the aim of a game, this is only a technical approch.

When I was looking for chess game on internet, I only found "beautifull-commercial-games" and "horrible-free-games". That's why I decided to write my own chess game, and I hope I've reach the equation : "beautifull-free-game".

So, you can play on internet or lan (classic host-client management) or you can play in solo mode (a basic AI I've writen...).

This game is totally free, and you can download it here :

or directly here :

Have fun !

I had the same log and crash.

PIII 600
ATI Rage Mobility 128

I tried it in both 32bit and 16 bit color modes (DirectX refuses to make a D3D device when my card is in 32bit mode but openGL seems to work all the time)

Okay.. I promised I'd try it out when I got home. On my machine with a Voodoo 3, it crashed on startup. I'm guess that since other people had that problem, it's just an unsupported feature that's causing the crash. On the machine with a Geforce2MX it ran great, right up until I was about to beat it. The computer sat there for awhile like it was thinking, then boom.

I like the AI too. I'm probabaly not the best of chess players, but it took me like 8 games before I got close to winning. Gonna go try again.. :)

its great. it looks great, the ai is great etc.
just one note:
is there fullscreen supported? i run normally at 640x480 and then your window is too big...

btw, it uses perpixeldotproducts, namely i guess GL_ARB_texture_env_dot3 or however called.
gpu's that don't support that will crash. voodoos, tnts etc..

Really want to try it out but it doesnt run properly:
1. The main window is in the bottom-right corner of a screen.
2. Runs very-very slow. Like 1.2 fps or so - looks like a software mode?

I have P3-750, 128mb, TNT, Windoze XP

Hi Davepermen,

you can modify the window size by clicking on F11 or F12 (-/+).
The window modes are : 320x200, 640x480, 1024x768, etc

The fullscreen mode is not supported. It's a good feature, but in a chess-game case, I think people rarely will play in fullscreen (they often are at work or other) :)

Exactly !

Worked fine on my PC, although bigpen has a point. I was having a lot of trouble distinguishing between pawns and bishops.
Why not make the pieces a well used format, like 3ds, and then have some form of archiving method, to make full sets. Then you could have people making their own custom chess pieces (And maybe boards) for the game. Just think, Star wars chess on PC :)
And what about model animations? (Don't mind me, Wizards Chess just sprang to mind...)
