How can I access the C++ source associated with the rgl function shade3d. More specifically, I'm interested in the part of the code used by arrow3d to draw arrow heads.
I'm not familiar with how GitHub is organized and I've put in a lot of effort doing searches there and on the web in general. The result has been a few fragments of rgl C++ code but not what I'm looking for.
