Hallo,
could someone maybe help me do something against my headache, which has its reason in the buggy patch attached (open "move-in-space.pd")?
Problem: I want to move and scale a primitive like [cube] or [sphere] etc. so that both its ends fall on two given points in the 3D space. I currently use a combination of stretching with scaleXYZ, translating and rotating the [cube]. Lok in [solid-link] for details. It's very likely that I do the rotation stuff wrong, however I can't fidn the right way. Sometimes it sucks being an audio guy primarily.
In just two dimensions what I want to achieve already works as can be seen in attached patch - which requires [list] btw. However as soon as the two points don't fall into the (x,y) plane anymore, that is, one of them has a differenc Z-coordinate than the other, everything falls apart.
I kind of know that the order of rotations probably is wrong, that I should use some kind of matrix transformation instead, quaterions, etc. however I'm so confused now: Any help is appreciated!
Ciao
