| Parameter | Description |
|---|---|
| q1 | The first quaternion. |
| q2 | The second quaternion. |
| t | The interpolation parameter. |
quaternion The normalized linear interpolation of two quaternions.
Returns the result of a normalized linear interpolation between two quaternions q1 and a2 using an interpolation parameter t.
Prefer to use this over slerp() when you know the distance between q1 and q2 is small. This can be much higher performance due to avoiding trigonometric function evaluations that occur in slerp().
