Hi gang,
with my partner we were discussing crossproduct "theory" and I'm not
sure what to believe or think.
I was persuaded that the result of a Cross Product of a PointPosition
(x,y,z) and a vector 0,1,0 plugged in a the PointVelocity, would give a
particle orbiting around 0,0,0 describing a perfect circle.
In fact, not exactly.
with simulation substep 1 I get this :
with simulation substep 10 I get this (but it travels much slower) :
So my question is : Is this a problem of approximation from the or the
computer, and then the mathematical nature of cross product is able to
"describe" a circle.
or is this a normal behaviour, considering that the cross product vector
is pushing in straight line a particle and that it could never
"describe" a circle.
