rotateY<T>(a, b, rad, dst?): T
Rotate a 3D vector around the y-axis
Type Parameters
- T extends BaseArgType = number[]
Parameters
- a: BaseArgType
  The vec3 point to rotate
- b: BaseArgType
  The origin of the rotation
- rad: number
  The angle of rotation in radians
- Optional dst: T
  The vector to set. If not passed a new one is created.
Returns T
the rotated vector
