Random Ray Angle Distribution:
In writing the code to select photons of certain energy levels and output their angles through space, I've run into a case that I can't figure out if I like. Firstly, it is clear that, to pick a set of random rays in a range defined by polar angle
$\theta$ , one cannot simply choose$\theta$ values uniformly. This will result in the following undesired distribution:
This leads to my case: I am getting a similar distribution, though I can't determine whether it is the fault of the above error or a byproduct of using an exponential ray distribution that favors smaller angles (closer to the center).
