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.
Alan: I can do it for you. It will take me 1 day and I will charge you $30. If you want to save the money here is how you do it in a nutshell: Take a picture and create a relief picture for use as a displacement map (white is close, black is far). Model the gross geometry using a very detailed mesh. The detail should support the smallest detail in the relief. It will work well. Here is an example I did for a person who need a bubble gum machine.
The coin box was an intricate relief which would be ridiculous to model without displacement maps. Hope I have/can help! -David Dara (David@DaraProductions.com)
