Basically you are of course absolutely free to create any type of point
cloud file from your STL: it may even contain many points on the
surface of each separate triangle to have a sufficiently dense point cloud.

In case the density is no problem, than the best apporoximation
of the original CAD model is given by the three vertices of every
triangle (of course three coordinates per vertex). These points are
on the original CAD-surface, while the flat triangle inbetween is just
an approximation.

Hope this answers your question.
