Re: hello? -help with a spinning bucket!
from your responses, I gather that my scheme might work :-)
question is, would it be efficient, in terms of time of computation required, and would it be beautiful, in terms of code. for the latter, at least, I believe not.
the beautiful thing to do would be (I think) to put in some code such that the axis of rotation and the zero point of rotation can be defined not only absolutely, as they seem to be now, but as being alligned with some existing vertex (line between two points), or an existing point, respectively. that would make the whole thing automatic, meaning that no extra code would have to be added by the user to manually update the position.
for example, perhaps a new rotation engine could be coded that would accept as input a named point and line in the simulation, so that variation of the position and orientation of this named point and line would be taken into account. in this way, 'rotations' of arbitrary complexity could be modeled, one extra line of code simulating the resulting action of one rotating motor. or linear motor, or any other actuator.
does such functionality yet exist? I suspect not? it depends on how many ways the vector3r can be defined.

Watch out, though, O.run(1) might return _before_ the iteration finishes
(it launches thecomputation in background)! O.step() will wait. Or use
