What is VoxBo made out of?
VoxBo is written mostly in c/c++, although we continue to distribute older code written in IDL as non-essential parts of the package. All told, VoxBo’s source code amounts to well over 150,000 lines (including a bit of redundant and obsolete code, as well as whitespace and comments). Although VoxBo used to depend on IDL, it no longer does. That said, some people like specific features of the old voxel surfer and we continue to distribute it. Because IDL costs money, and we’re trying to build free software, we’d like to phase out the old code eventually, but rest assured that you do not need to invest in IDL to use VoxBo.
