Grimm, not sure what's going on. ISL Previewer creates a simple preview texture, launches indigo and loads the preview scene. The "Problem launching indigo" message means that java wasn't able to launch the indigo executable. It could have something to do with your version of Java, but I'm not sure....

Might be better to post this in the Skindigo forum.

They haven't been implemented yet.

You're really determined to learn ISL.

The best way to learn is trial and error. Set up a preview scene with a shader material, and try to achieve different textures using a trial and error approach. Time consuming, but it's the best way to learn IMHO.

Ah. Not sure if GLSL is supported by GeForce4.

Tools->GLSL Log

Hmm, suzanne should load automatically when you start. Is there anything in the GLSL log?

I don't think I ever tested in Ubuntu. :) Hmm, what color is suzanne when you load? I haven't had a chance to work on this in a while. Not sure why indigo won't launch if you have the right path set up. Sorry, I know I'm not much help. Hopefully I'll have time to update ISL Previewer in the near fut...

You can also define a wavelength dependent shader like this:
which operates on each wavelength independently.

What's the range of wavelen? [0,1]?

MSUdom5, OK, now I see it. In the manual, under diffuse, it states that albedo is a wavelength dependent parameter. Yep. The manual is your friend. :) What I could use more help with, generally speaking is "how would I know that a wavelength dependent parameter requires a vec3". This is also in the...

Albedo is a wavelength dependent parameter, so an albedo shader must return a vec3. Since bump and displacement are wavelength independent, they need only return a real. So the function def eval() real : noise(getTexCoords(0)*30.0)*0.002 Must be: def eval() vec3 : vec3(noise(getTexCoords(0)*30.0)*0....

Which Indigo Shader tutorial are you talking about? Could you post a link to it?

Make sure you keep the original libraries though as applications which need 2.4 support won't work (e.g. Audacity).

PNG = Uncompressed format which is awesome for high quality stuff.

Of course, you meant to say "lossless" instead of "uncompressed". PNG is a compressed format.

Thanks. See? Wasn't so bad, was it?

Cause that's photoshop's job.
