Shadow Map Generation

[moonwalkercs]

I'm trying to implement shadow maps in GLSL, but my the shadow map texture I'm creating doesn't seem to be working correctly. Does anyone know of a tutorials that covers shadow map generation or source code that shows how to do it?

Thanks

If I remember correctly, there are shadowmap examples in nVidia SDK (http://developer.nvidia.com/object/sdk_home.html) and maybe something can be also found in ATI SDK (http://www.ati.com/developer/radeonSDK.html)
