There are two way of making triangulated models. The first
is to explicitly input boundary coordinates and wavespeed (actually
sloth values) with ``trimodel.'' The second is to make a uniformly
sampled model, perhaps with one of the model building utilities
above, and then use ``uni2tri'' to convert the uniformly sampled
model to a triangulated model. (Please note, that this will work
better if the wavespeed model is smoothed, prior to conversion.)
These programs are
- TRIMODEL - make a triangulated sloth (1/velocity squared) model
- UNI2TRI - convert UNIformly sampled model to a TRIangulated model
- TRI2UNI - convert a TRIangulated model to UNIformly sampled model
