Hi,

I’m having some difficulties finding the proper specs about how animated rotation values are to be interpreted.

Assuming the following examples (all with linear interpolation):

example 1:

- 2 animation keys: 0, 180

I assume that in this case a counterclockwise rotation of 180 degrees has to be performed, since 180 is a positive value. Is this correct?

example 2:

- 2 animation keys: 0, -180

clockwise rotation of 180 degrees, since -180 is negative

example 3:

- 3 animation keys: -360, -180, 270

key 1 to key 2: clockwise rotation of 180 degrees

key 2 to key 3: counterclockwise rotation of 90 degrees (since 270 is positive)?

example 4:

-3 animation keys: -360, 180, -270

key 1 to key 2: counter-clockwise rotation of 180 degrees

key 2 to key 3: clockwise rotation of 90 deg (since -270 is negative)?

If the above given examples are true, how do I specify a clockwise rotation of 90 degree from key 2 to key 3, in the following case?

- 3 animation keys: 0, 90, ?

Are those the proper ways to perform the rotation given those key frames? Can someone even point me to the definition in the specs?
