When to Use Interpolation
You can use interpolation to simulate motion between key points in which there is a continuous value that changes at the end key point. You cannot use interpolation if you are simulating jumps in motion.
For example, you can use interpolation to approximate motion using:
You must apply a motor , force , or gravity to move mates through key points.
Using the interpolation method is useful for view orientation changes, to avoid abrupt changes in motion.
