Digital models for hire
They're doing amazing things with computer generated imagery (CGI) these days, creating fantastical and unreal characters, scenary and special effects for the movies. But what if you want to put an object from the past in your film? You could go out and find someone that has what you're looking for (like a classic car, or an old kitchen appliance) and pay them to rent their treasure for the duration of shooting. Or... you could pay someone to rent/generate you a computer model that you could animate and drop into your scene.
You could be that someone. A database of full, three-dimensional objects could be created by "scanning" real items now before they're gone. Then you could place them in the background of any movie, or use them to accurately create a CGI model if you need to have your object animated.
Now... how much would you have to charge for a model? How would you manage the rights to the use of the model? Does the technology for creating a high definition scan for objects of any size already exist, or would it have to developed?
