Maxwell Render

Hi,
I'm looking for some decent wood texture maps that include a 'real' anisotropic direction map.

Something to produce results like this: http://www.cs.cornell.edu/~srm/publicat ... 5-wood.pdf

Cheers,
.Sam

Interesting paper. Having read it, I don't think an aniso map is going to get you the effect you are looking for.

Help! I'm dispersing into a haze of probability!

I'm affraid you're right. But maybe with a few layers I could get somewhere close.

... any ideas... ?

This is the effect that I'm always talking about as to the difference between a nice hardwood floor and some cheap laminate... very interesting to know the science behind what my eyes have been telling me.

Best,
Jason.

I've got some ideas, but I think you would have to make a very intricate aniso map where the angle coincides with the grain of the wood. Interesting, thought provoking topic!

Well if we had the time/budget here I'd get a wood panel and take photos from all different viewing & light angles myself, and see what I can make of it... but though, surely someone has already done that somewhere....

Cool I found some of the files and the shader coder they've used:
http://www.cs.cornell.edu/~srm/publicat ... d-data.tgz

This is the most interesting map:

Description in the shader for this map:
containing 3-channel texture modulating fiberAxis across the patch. Values are mapped [0:max] -> [-1:1] for each component, since most image file formats are unsigned.

I wonder what would happen if one would convert this from a vector3 into a anisotripc map. Any idea how to add the colour channels in photoshop to get a good result?

I just wanted to bump this thread because I would really like to see this type of mapping featured in some Arroway wood textures sets and supported by Maxwell

Best,
Jason.
