Demo time again. Some transparent shadowmapping goodness for your pleasure.
Enjoy!

What about those new ARB extensions that support a new version of vertex and fragment programs? Don't they support a high-level shading language?

GL_ARB_shader_objects, GL_ARB_vertex_shader, GL_ARB_fragment_shader and GL_ARB_shading_language_100, yeah, it's what was formerly known as the GL2 shading language or glslang. It's a high level language, though we need official driver support for it before I can release any demos on it.

Humus, I was wondering... Why would you actually want to use shadow mapping instead of shadow volumes? I think (stencil) shadow volumes provide more accuracy on today's hardware and are easier to implement.

Stencil shadows easier to implement? That gotta be a first. Never heard that opinion before, most people including me think shadow mapping is much easier to implement. It's also more generic, more scalable, faster, and more flexible for extension etc. Sure, stencil volumes can have better quality, today anyway, but that's about the only thing where it beats shadow mapping. IMO of course.

You're actually right humus, with higher precision shadow maps can produce better results. I haven't been succesfull with either shadow volumes or shadow mapping. I've been trying to get a working shadow volume demo for about half a year now and so far I'm only getting wrong results. My shadow mapping attempts haven't been succesfull either. Is someone with shadow volume experience reading this (especially with 3ds models), please mail me (neokenobi007@hotmail.com). Or can anyone point me to an easy to implement shadow mapping tutorial?

Greetings Humus, I've got a GeForce FX 5200 (VS & PS 2.0) but the demo doesn't run quite right.
The shadow on the walls keeps shimmering on and off. Do you know why this might be happening?

Thanks.
