Prompted by a post a few days/weeks ago I looked up a project I worked on a
few years ago
This is an actual mainboard (Intel DK440LX, see pic)
I stopped working on it because I couldn't figure out how to make the
printed tracks and the silkscreen (the white prints). I tried scanning and
photographing it but it didn't come out good enough. And handcoding all the
wires and texts is a bit too much work

Ideas, comments, complaints etc welcome

Okay, WOW... ambitious!!!

For the silkscreen, how about building a hi-res texture for it in
Photoshop/Gimp/etc? You can use the circuit traces as a bump_map too to get
a raised look.

Also, try adding a little "specular" to your "finish" and you'll get that
silicon look. I'm guessing maybe 0.4 would be a great value.

Add a skysphere with some pigment to bring out the reflections.

I can't see the holes in the IDE slots -- did you do a "difference" to
create those? If so, try making the cylinder(?) a little darker than the
plastic you're "punching in" to bring out the holes a bit.

This is freeking' sweet.
I love this board (pun intended!)

For that you need a hires scan and that gets frigging huge because it's a
very large board (305x330 mm). I have tried it though but it didn't work
out, the scan never came out good enough

There is a skysphere although it's pretty dark

I don't understand which holes in the ide slots you mean

You mean the holes in the board? they are that light because of the
underlying plane

Thanks :)

Me too, only problem is, it's dead :(

What about drawing it? It might take a really long time, but it would
guarantee really good results.

Ah :-)

The white slots in the middle-top of the image. There are a series of
holes -- ya know, I have no idea why there are there, really -- in the
middle. I think they actually might be rectangular holes, come to think of
it. Same with the orange slots. A macro could fill those in really easily.

Nope; the ones in the plastic slots themselves. For the cards :-)

AH, but it shall live on forever as a work of POV-Ray art!!! :-)
Unless... you don't mean povray.binaries.images, do you? *gulp*. This board
is the highlight of my day.

Hi
Good work on the modelling! Pure SDL?

Take a look at this neat image by Rick:
http://kitty5.com/portfolio/3d/3com.asp
IIRC he put the nic in his scanner and used it as texture afterwards, quite
nice result, no?

Perhaps, and just perhaps, you could get decent result enhancing the scan in
a paint program to create a height_field which you could then trace()
triangles or boxes onto?

Thanks, yes it's pure SDL

Looks very good, I'm nowhere near that kind of result

I tried that, maybe I'm doing something wrong but the scans didn't come out
good enough to turn into a height_field. Another problem with scans is that
when you render a closeup of a part of the board, it has to be very high
resolution which in turn will make it very big

BTW: Since your image will have a lot of straight lines and a few small
curves (circuit end-points mostly), you'll get a lot with interpolation. The
lines won't be affected much, but the curves will smooth out nicely when
interpolated.

I keep meaning to do another one of these, I do have a few old mobo's
floating around so if I get chance to make a start will see how the
technique works on bigger more compilcated projects (and hey, I already
have a PCI card for the mobo :)

Just interested, how would you go about creating the tracks and silkscreen
of a large board?

Same as before, slap the whole thing on the scanner and use said image as
texture and guide for positioning components.

If you can find the thread in which I posted the original image you will see
its a very simply model with all the parts as a csg union and the scan
texturing everything.
