public static Vector3 Slerp (Vector3 a, Vector3 b, float t);


球状に 2 つのベクトル間を補間します

Interpolates between a and b by amount t. The difference between this and linear interpolation (aka, "lerp") is that the vectors are treated as directions rather than points in space. The direction of the returned vector is interpolated by the angle and its magnitude is interpolated between the magnitudes of from and to.

The parameter t is clamped to the range [0, 1].
