Hello, I've got a question I'm wondering about quite some while now. The question is how much structural difference is necessary for a model to clearly become a new model? When I fold something from Crease Pattern the structure of the model should be the same in the end, no matter how I arrived there. But that leads to another phenomenon, it is possible to use a completely different folding sequence to come to a structurally identical model. So is this still the same model? I mean the outcome may be similar, but the path to get there isn't. The question gets even more complicated when I fold a model from a picture only without a CP or any other clues. I've done that before so it is clearly possible. But then I also had the case that even if it looks the same, it is structurally not the same because I started with a differently shaped paper (square instead of rectangle). Of course if I fold something from CP or picture I attribute the model to the initial designer of the model, because if it hadn't been for his input, I would never have gotten the idea to fold this model. But still I sometimes wonder whether this is even correct. I know at least three models by heart where I found a very nice folding sequence to later find out that the original designer folds them completely different. Two of them end up with minor differences at the end. The differences are of structural nature and not openly visible, so the models look exactly the same, even though they are not. I wonder this because sometimes for really simple models someone folds a single fold differently and calls it hos own model. Here I do all the folds differently, but end up with a similar looking model and don't attribute it to myself, even though the difference is much higher than on the simple model with just a slight difference. Know what I mean? So what is your opinion to this subject?
And then I've got a second question that is even more pressing for me. Lets say I've derived at my own folding sequence for a specific model and I want to share it with the world by publishing diagrams for it, am I allowed to? Do I need permission from the author? I mean it is not something he came up with, just the result is the same and like I said, maybe even not completely. I guess it would be the nice thing to ask, but the folding sequence is my own and not his. I'd really like to hear your opinion on that matter. Nice Greetings Anna from Vienna, Austria.
