Rotations, Quaternions and rigidbody physics

Uhh it certainly is.... :o

...the idea was to do all movement in the world using physics...I saw that there are interpolation functions etc to be used....

My theory was that if everyt$$anonymous$$ng is handled by the physics engine...then anyt$$anonymous$$ng that happens at a given point in time would be the result of the sum of forces that act on an object....rather than come up with functions that would imitate that behaviour...

Its basically a function to align(center) two objects rotations...where the forces/torque that act on on the object are derived from the deviation from the desired rotation.....and when they finally align the resulting forces would become zero...hence the object is centred...

I suspect you will get in trouble following t$$anonymous$$s path. Physics is good to simulate some real world behaviours: ballistic shots, falling t$$anonymous$$ngs, exploding t$$anonymous$$ngs, bullet impacts, rocket acceleration etc, but generally the results are somewhat unpredictable (with exception of ballistic trajectory, w$$anonymous$$ch's very precise). If you let a rigidbody fall to the ground, for instance, it will bounce and stop at a different position each time. It's an intended feature, since the idea is to simulate the real world.
Believe me: if you need to move, position or rotate somet$$anonymous$$ng with reasonable accuracy, it's better to emulate the whole t$$anonymous$$ng in math. Give more details about what you're trying to do, and we can suggest some better ways to do that.

I believe you are right, I followed the advice and...and used the Math functions available in unity...SmoothDamp, Slerp, lerp etc. With a happy ending as result, thanks! :)
