Roadmap

rte solver in 2D only has 1 directional dependence, it is easy to handle the integration over velocity space.

For the meshes, unstructured mesh can be used directly from femm. Or just copy the relevant part of code and paste here.

For ray tracing, the geometry information has to be stored in prior. Storage efficiency needs to be considered.

geometry stored now. In order to sustain efficiency, it is not good to export them?

update: export the variables will duplicate the memory, in matlab, the parallelism for such tracing algorithm is not perfect yet.

Back to this roadmap, Huh.

now, geometry is stored in a very old-fashioned way, storage almost doubled. Exporting is not necessary for normal computing, but it will be useful to serialize when computing with large data, saving globs will be necessary.
