Has anybody given a thought of my idea that is based on the Rodrques formula saying that every non-parallel movement can be defined matematically with one finite rotation around a vector, that can be found with aid of vector-geometry.
My idea is to make a complete 3D-model of a house separating each item on their own layer. For instance a 2"x4" timber is located on a layer called 2x4. If I cut or drill the timber it will still remain on that layer.
OK - now I have the house finished and I want to "unbuild" it and record the "flying" materials to their own packages (each package displacement and size will be asked or resumed). If the flying can be recorded so that I can really see the "film" including movement of the materials and filling the packages at the same time as the house will lose the corresponding elements. My idea continues from this point showing the film in a reversed sequence, where the materials are originally placed on the plot of land and they start flying so that finally I have a complete house within few seconds on the screen.
This can be applied to any assembly of machines, equipment etc.. I have some code in C++, that manipulates the vectors, but the complexity of the problem would take a lot of my time. I can do it in prison, if I will be allowed to take my PC there when I get doomed for at least for a life. The crime is not yet done...
