AutoREALM
Vector based drawing software designed for RPGs
...Some attempts to rewrite it in other languages were done, but currently (since January 2012) there is an attempt or rewrite using those technologies:
_ C++11
_ wxWidgets 2.9 (will be 3.0 when it will be released)
_ openGL
_ pluma framework (a fixed version located on bitbucket)
The design of the actual C++ code-base primarily targets clean source code and high modularity of source code, to allow easy reuse of the code and fast learning for people who might join the effort.
Current development is located on https://bitbucket.org/bmorel/autorealm . Howerver, older repositories are still here in case someone would like to consult them, and to allow easy access to algorithms they might contain.
