hey there,

I need to use something like color_map on normals.

let me explain myself:

let's say I have a texture with:
pigment{ wood scale <.2, .2, 1> }
I get a bunch of concentrical rings, in 2 colors.

now if I change it like this:
pigment{ wood color_map{[0 rgb 0] [1 rgb 1]} scale <.2, .2, 1>}}
I get the same rings, but instead of 2 colors I get a gradient.

now, back to my problem: when I use "wood" in a texture's normal, I get
concentrical rings in 2 "colors", that means I see one ring flat, one right
raised, one flat, one raised, so on..

what I need is something similar to "color_map" in normals, so I can get a
grandient in the mapping. I've tried "normal_map" without any luck... I've
also tried the slope_map but I don't see how that works.


any hints would be really neat! :)

Thanks,
Alex V.
