anyone care to give some guidance on adding realism ?

Like 99% of the rest of the places out there, the shop i work at is rather slow right now. However, there seams to be some interest in us doing some more custom coffee tables.

Interest that started because of this custom table Boss Jr did a few years back for a local BMW dealer, but the new interest is coming from some Audi owners.

Interest is great and all, but you need a product if you want to sell something right?

I suggested doing some concept sketches to show the guys, simple stuff to kind of get the ball rolling, but Joe Jr wasnt so sure about spending time to chase something that might never happen.

so i went hiome and did my own CAD file. An Audi RS4 line drawing, which will fit quite nice on a 40 x 20 coffee table.



and would be etched on a table like this:

the problem is i cant work in color, so highlighting curves and such is a bit of a pain, especially considering my artistic talent is .... well .... missing since birth. lol

any suggestions on how to ad some realism ? i think that tracing the reflections looks like butt, but at the same time leaving them out doesnt look right either

Maybe some sandblasting or media blasting combined with some etching solvents to darken area's and so on, very cool idea BTW.

i was thinking more along the lines of adding the realism to the cad file, but your right about the sandblasting. I could very easily draw the reflections in so they are part of the laser etching process, then mask those areas off and sand blast them after the fact.

or while wheel them or anything else really, anything to finish them different from laser etching

I'm not sure how a cad file works but even the etching part once it's finished may just be hard lines. I photoshop programs and so on, you can actually feather the lines to smooth them or soften them. Sometimes adding "noise" or speckled type of distortion to an area gives the same effect. I would assume that sand or media blasting would create subtle "noise or haze in the image sections" Photoshop has various brushes in hi res to create these glares or different reflections of light. I think you may have to first add color to the whole image and erase from there, maybe an off white or grey.

I've seen these tables done out of airplane wings on discovery I think. Once it's polished they detail it like you said.
