We really should seriously consider a streaming model
for the TIN library. If this library is intended to be
decoupled from OpenJUMP and used in multiple JavaGIS
projects, then dealing with huge data sets that dwarf
available RAM would be a very big plus.

The thing I like about LaTeX and other TeX derivatives
