3D Procedural Scratches on Chrome

If you model scratches as the places where a surface intersects random 3D space-partitioning cutting planes then it might be possible to make scratches on metal that seem to make a halo around highlights.
Fill space with randomly located point/normals -- those are planes. For each surface point rendered, see if it lies close to within a plane. Then it is a 'scratch.' Light accordingly.
Advantage: texture is not 2D mapped. No UVs or pinching at poles.
(don't know if this would work)

This reaction may be a little late but I've been away from the forum for a while.. (very busy with school
)
I've already achieved this a while ago with normal bumpmaps. I also uploaded it to the MXM gallery but I don't think people
see much of a difference.. It is clearly visible in an animation of a turntable, but I haven't made one or tested that yet.
Anyway here's the link to the MXM gallery:

It's very good but I'm particularly interested in seeing Maxwell get solid 3D procedural textures, and random cutting plane scratches might be a good one to have.

Well that discussion has been held many times before, Next Limit didn't tell us anything..

This wish is pretty much as old as Maxwell itself... unfortunately...
Manyway... let's +1...

I think we'll never seen any procedural maxwell shader until Maxwel 7.0.
