Metal roofing

Can someone point me to a cal file, or a method to make a metal roof?

Something with a profile like this ASCII art
        __ __
_______| |_________| |____ etc...

Even a brightdata (without the ridge geometry) that would indicate the
ridges.
I thought there was one in the sample Radiance files (cabin, etc) but I
can't find it.

Thanks

BTW - progress renders are here...

Here is version 1 of our remodel

http://www.geocities.com/rastermon/Version1.html
The designer is using Sketchup and I'm rendering with - of course -
Radiance. Composite done in photosop. Radiance view did not match pic, so I
did a little skewing in PS.

Thanks for all the input on art lighting - I'll post pics as it comes
along.

Hi Thomas!

They were directed to north because they had to be huge and you had to
avoid direct sunlight. Northern light also varies not much over the
day.

Ok... that is what I wanted to describe as continous ;-)))

Only directional light would indeed be irritating but you need a
certain directional component to render the shape.

Well, if you have no clear window at all you also might get mad.

No! Don't use that stuff! We had an exhibition pavillion in my
university built with honeycomb insulation between two glass profiles.
The profiles alone might have worked well but the building inspector
insisted in an insulation of the wall. The honeycombs diffuse the
light so much that there is hardly a directional component left. It
looks odd and the sculptures and architectural modells are shaded
poorly even if the interior is rather bright.

That sounds interesting, as I actually do not have experienced such a room.
Were the panels used on all sides or to one direction only? My idea was to
have a big diffuse-translucent wall (only) to north. Also Ithink that for an
exhibition pavillion, especially for architectural models, a diffuse
environment is a terrific idea. All those I know use spots to take fotos of
their models and to show them (of course with a diffuse environment around).

But I really wonder on the impact of these panels on color, did you
experience any noticable effect? It would also interesting to know what
happens after some years, at least with those based on plastics (I would not
worry about the glass-based products, but I am also not sure here).
Christopher has done validation work on such panels, maybe he has more to
say about it.

Hi Rob,

One thing to try would be to use the corrug.cal which simulates corrugations. I know this is not exactly the same but it would give you the linear effect of such a roofing material. One could probably modify this with a step function to great a sharp cutoff versus what the smooth funtion in corrug.cal. Perhaps another option would be to engineer a simple repetitive cal with with perhaps three different value (color at top of metal rib, color at bottom and shadow). Yet another alternative could be to make an image map in Gimp (or photoshop) that can be tiled to create the effect you want.
