My mathematical skills are also poor, but I was thinking - without ever
having seen 'maketree' - that the macro uses only two sets of data to
generate the spheres and cones: their position and size.

In other words: The form of the tree is given by an infinite thin lines (the
positions of each sphere/cone) and the thickness (the size of each
sphere/cone).. That is the offset from the infinite line; the distance.

So if you wanted to replace the spheres and cones with triangles, you
woudn't need to remove any bad triangles. You just have to follow the
infinite thin line and make a circle of points, for each step.. To obtain
the same level of smoothness you will need to increase the density compared
to a tree with spheres.. But apart from that.. I think it's possible.
