Function lerp

lerp<T>(a, b, t, dst?): T
Performs linear interpolation on two quaternions. Given quaternions a and b and interpolation coefficient t, returns a + t * (b - a).
Type Parameters
- T extends BaseArgType = Float32Array
Parameters
- a: BaseArgType
  Operand quaternion.
- b: BaseArgType
  Operand quaternion.
- t: number
  Interpolation coefficient.
- Optional dst: T
  quaternion to hold result. If not passed in a new one is created.
Returns T
The linear interpolated result.
