Eigen: Open source, header-only matrix and linear algebra library


Boost: A massive collection of open source C++ libraries.  In essence an extended STL.  Some Virtuoso libraries use portions such as ASIO or container classes.   Since Boost is a fairly heavyweight set of libraries, where possible any Boost functionality is optional.  


Assimp: Asset importer for 3D models.  Uses a uniform interface across various model formats.  Provides easy access to geometry,  lights, textures, and skeletal animation information.  Asset importing and formats can be excruciating to deal with, and this library solves most of your problems for you.  The Virtuoso model libraries use Assimp on the backend for importing models created by artists.  


STB Image: A set of simple image loaders.  Public domain C code by Sean Barrett.   Many other useful links on his site.
