You have failed to provide a complete, coherent description of what you
wish to do. In the absence of such a description, all suggestions are just
guesses. You need to think carefully about what information you want to
associate with each triangle and the appropriate data structure to use to
do this. You might do well to talk with a computer scientist about this. An
object-oriented framework seems like the natural approach. This also sounds
like the sort of thing Bioconductor might already have, so search around
there, perhaps posting on their Help list.
