Tree Modelling in Radiance

HI!

I was trying to simulate trees in Radiance and found 2 methods without building a tree:
1 a representative sphere with trans material.
2 a representative semi-sphere with iterated triangles to get a more accurate tree with gap. The second method is from 2015 Radiance workshop by Alstan.
From the pdf file I think it's a logical way to get more accurate trees. But I do have trouble to "procedurally fill areas" shown as below. I understand that this step is based on the rules controlled by the measurement, but measurements aside, if there is any resource you guys could point me to so I could learn to complete the process that would be very helpful! 
(Content and image resource: page 37 from "Quantifying Materials in Lighting Simulations" by J. Alstan Jakubiec and Priji Balakrishnan.)
I could generate random points on a surface in grasshopper, but iterating triangles is beyond my knowledge of grasshopper, and I didn't find similar questions on the forum. Thanks in advance for your help!

This is my first post here so please feel free to let me know if anything isn't clear or more description needed. Thanks!

Best,

XF

What about using Random Reduce?
