njUnitVector	Japanese
Converts an arbitrary vector to a unit vector.

FORMAT

#include <Ninja.h>

Float njUnitVector(*v)
NJS_VECTOR *v

PARAMETERS

NJS_VECTOR *v
arbitrary vector

RETURN VALUE

Size of the original vector. (scalar)

FUNCTION Converts an arbitrary vector to a unit vector.

EXAMPLE

The following converts vector v(3, 3, 3) to a unit vector.

NJS_VECTOR v;
Float scalor;

v.x = 3.f;
v.y = 3.f;
v.z = 3.f;

scalor = njUnitVector(&v)

% result %
v(0.577350, 0.577350, 0.577350)
scalor = 5.196152
