TRSL is a C++ library that implements several (statistical) sampling schemes behind an (STL-like) iterator interface. The library may be used e.g. in particle filtering. It is distributed under the Boost SL (BSL is a free-software license).
SL is a suite of C++ template classes that support
geometric computation (specifically adapted to OpenGL).
It includes many different kind of algorithms (linear algebra methods, coding/decoding tecniques, generalized data structures, utilities).
