Detailed Description

Sample optical Mie scattering using the Henyey–Greenstein distribution.

\[ P(\cos\theta) \propto \frac{1 - g^2}{(1 + g^2 - 2g\cos\theta)^{3/2}} \]

. Parameters:

• forward_ratio: probability of using forward vs backward lobe
• forward_g, backward_g: HG asymmetry parameters for each lobe
