Model Olympic medal
I have to model an Olympic bronze medal and am not getting satisfactory results.
I’ve tried bump mapping and displacement mapping on it’s surface but it’s not very convincing.
I have access to a medal and will try and obtain further images for more experimenting, but there must be a way (I’m happy to pay commercial rates) to obtain the relief data of the two surfaces from it.
Any advice would be very welcolme.
Thanks

PS fprgot to mention!
It’s the 1924 Olymipcs and it appears that the current commercially available models are all more recent.

You might be able to find a laser scanning service in your area.
Otherwise … I don’t know if this would work with such a shallow relief, but I knew a guy many years ago who created a depth map of sorts by putting an object in a pan of water that was titrated with some kind of substance (milk?) to the point where the deepest part of the object was barely discernable. Then he photographed it and equalized the photo to create a depth/displacement map. He showed the results and it actually worked fairly well. But the object he was “scanning” had much more thickness than a medal.

Wow Adam,
What an amazing bit of creative thinking. I’ll certainly try the technique in the future, but as you say I can’t see it working with such a shallow object.
Thanks for the thought though.

Yeah, I wish I could remember his name. He was a former engineer at Boeing and he was always coming up with clever ideas like that. Karl something….
