Ray Generator

Using Options -> Ray Generators -> 2D Circular Uniform Rays We can generate rays that are parallel to Z axis.

Then manually apply V0 and W0.

For parallel beam, set W0 to 1, U0 and V0 to 0.

For oblique beam, set U0 to 0, V0 to sin(radians(angle/2)) and W0 to cos(radians(angle/2)).

V0 represents vector direction in Y axis.
W0 represents vector direction in Z axis.
