Function normal

normal(out: vec3.Vec3, a: vec3.Vec3, b: vec3.Vec3, c: vec3.Vec3): 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: vec3.Vec3
  the first vertex of the triangle.
- b: vec3.Vec3
  the second vertex of the triangle.
- c: vec3.Vec3
  the third vertex of the triangle.
Returns vec3.Vec3
the output vector containing the normal of the triangle.
