Multiplying vectors

Vector multiplication can be considered a non-uniform scale. Instead of scaling every component of a vector by a scalar, to multiply two vectors, you scale every component of a vector by the like component of another vector.

You can implement vector multiplication by overloading the * operator in vec3.cpp. Don't forget to add the function declaration to vec3.h:

vec3 operator*(const vec3 &l, const vec3 &r) {

    return vec3(l.x * r.x, l.y * r.y, l.z * r.z);

}

The result generated by multiplying two vectors will have a different direction and magnitude.
