Preliminary study on luminous intensity distribution ...
2007-3-1 · This is because the direction of the normal vector varies according to the slope of the dome. Step 4: The first refractive vector is calculated by dot product equation, as shown in Eq. , using the refractive angle resulted from the Snell's law and the normal vector of the inside prism. The second refractive vector is also calculated by Eq.
