"The question is, would giving it to someone else who already own the head, would that be a copyright violation?" "That would be concidered Frankensteining." 3d Content seems to be me to be one of the strangest and indeed a unique area in relation to copyrights and intellectual property ownership. With many many different views. Saddly, I see two main controlling forces at work firstly, The my pockets are deeper than yours method, this is where a threat of legal action comes from a person or Co. that has the resources to take the matter to the lawyers. Both parties know that, due to the complexity of the issue it's going to be very very expensive. The poorer party normally agrees to the terms of the richer. We also see this method use indirectly as control over shops and outlets. You sell this contested product we will also sue you, rich wins poor looses. The other method I would call public crucifixion, this method of control is where a community, labels the goods and/or creator with nasty names, using public ridicule and abuse. This method is often overtly fuelled by competitors. A business normally doesn't want to be called Witches, Hackers, Pirates or Frankensteins. They want their community and potential customers to trust them. To save face and their market place they drop the contested product. The result is mob rule. In both these cases the real issues remain unresolved. There is no legal resolution and injustice is the inevitable results. Issues of what is right or fair are sidelined by the rich and powerful. Innovation and creativity may be eventually extinguished. The old laws of ownership and usage rights have not transferred well into this international/digital age and lawlessness prevails. I'm no lawyer but I know laws have national boundaries. So what is illegal in New Zealand may be ok in the US. Here it is illegal to rip your purchased CD to play on your MP3 player, for your own use. China has different set of copyright laws. Consensual sex in NZ is legal for 16 year olds, illegal in most of the US. By what method do we determine what is right or wrong? Returning to geeps point, I feel for personal use, it should be allowed under fair use. To sell the results as part of your own product, I don't have pockets deep enough or the courage to express any opinion in this forum. But rest assured I wouldn't do it.
