A C++/Qt parser for the Walls .srv cave survey data format
I'm on a crusade to liberate survey data from the Walls format so it can be used in modern 3D cave survey viewers like Cavewhere and Breakout. The Walls format is far more complicated than any other cave survey data format I know of, which is probably why I haven't known of any other programs that can read or write Walls data. But that will soon change thanks to this library.
Right now this is just a parsing library to be embedded in other programs, but I'll probably make a command-line exporter for some other formats soon.
I've been careful to write very clean and precise code for this parser, but the documentation is...pretty much nonexistent :) If you're interested in using this for your own program, let me know and I'll write up documentation and help you get started.
Building
Just open dewalls.qbs in Qt and hit run.
