|
Returns one of the normals of this vector. Computes normal by setting one component 0(usually the z-component), exchange the two others and negating one of the two other components(usually the y-component) if either the x or the y-component is not 0, then the normal vector is in the x-y plane, else it is in the x-z plane. for example: normal([1,4,5]) = [-4,1,0] |
|
Returns array with 'num' normal vectors. returns an array of normals with length 1 by computing the normal in the x-y plane (if there is one, else x-z plane), then rotating this normal around the axis specified by this vector 'num-1' times with angle 360/'num'(resulting in 'num' other normals |
