Another crack at the brushed metal table look.

Changes this time:

I've made the table colour darker, and very slightly blue-tinged. Looks 
more "metal" to me now.

I've layered a wrinkles pattern on top of everything to give the table a 
less purely flat appearance. Looking at it here it almost looks like 
I've put too much in, but real surfaces tend to have a fair amount of 
flex in them, so maybe it's OK.

A bit I was pretty happy with: I've layered two patterns on top of each 
other, and made the scratch highlights in the second one reflect more 
light in order to make the scratches show up more. But this only happens 
if there is a bright reflection falling on them - otherwise they fade 
back into the normal surface. It feels more like how scratches catch the 
light in reality to me.

This one is rendered with radiosity.

Technique:

The blur is a simple average of 20 textures with a gradient z pattern 
(with a 1% random variation).

The scratch pattern is simply crackles stretched about 60 times in the x 
axis.

Two scratch patterns are layered on top of each other in a texture map, 
with the one with the highlights only showing through in the top 7% of 
the map. It is identical to the other pattern, but has a higher 
reflectivity.

As I said above, wrinkles is used in a normal_map in each blurred 
pattern to give the surface some large-scale flex.

And that's about it.


Any improvements you think can be made?

Cheers,
Edouard.

And because I'm a huge Photoshop fanboy, here's the above with "Focal 
Blur", "Glow" and "Lens Distortion" filters applied!

The original is largely beter than the photoshoped one.

Great image.

That's pretty compelling - that double image effect around the sphere 
and the color bleed on the cube.  For some reason the metal is making me 
think scuffs more than scratches - I think it might be the scale of it. 
I like that it's not 'flat.'  Anyway good image.

this is a typical raytracer purist at action. :)

Heh. Like the chat today on #imp.

<PovAddict> I think it *can* be done with such controls *and* pre-rendered
<PovAddict> when you press w to walk, it would start playing the walking 
video
<PovAddict> when you release, video would stop whenever it reaches a 

<+Noodles> I guess that might work
<PovAddict> then I guess you could also have FPS-like controls 
(ctrl/shift) to change walking speed too
<+Noodles> Sounds like it's almost easier just to make an FPS with OpenGL :)
<PovAddict> raytracing ftw
<+Noodles> heh

GPUs render fake stuff.
