Function normal

normal(
    out: vec3.Vec3,
    a: readonly [number, number, number],
    b: readonly [number, number, number],
    c: readonly [number, number, number],
): vec3.Vec3
Computes the normal vector of a triangle defined by three vertices.
Parameters
- out: vec3.Vec3
  the output vector to store the result.
- a: readonly [number, number, number]
  the first vertex of the triangle.
- b: readonly [number, number, number]
  the second vertex of the triangle.
- c: readonly [number, number, number]
  the third vertex of the triangle.
Returns vec3.Vec3
the output vector containing the normal of the triangle.
