Thor is an open-source and cross-platform library written in the programming language C++. It is an extension to SFML, a multimedia library with functionality for 2D graphics, audio, network, user input and more. While SFML provides rather basic, generic features to allow a wide range of applications, the Thor library comes with high-level features that base on this framework and that are supposed to help in daily C++ routine, especially with respect to graphics and game programming.
To use Thor, you need a compiler compliant to C++11, for example Visual Studio 2010 or g++ 4.6.
Features
The Thor library consists of several small modules, as shown below:
| Animation | Classes to animate sprites and other objects |
| Graphics | Various graphical functionality like big textures or color gradients |
| Input | Actions to combine real-time input and events, callbacks, enum-string conversions |
| Math | Random number generation and Delaunay triangulation |
| Particles | Particle system with emitters and affectors |
| Resources | Generic resource manager with automated loading and shared access |
| Shapes | Concave shapes, arrows, and other predefined figures |
| Time | Pausable clocks and timers, optional callbacks at expiration time |
| Vectors | Dot and cross products, angles, length, and more |
License
Thor is completely free to use, for both open-source and closed-source projects. It is licensed under the zlib/libpng license. Even though the license doesn't enforce this, I would appreciate a short acknowledgement in your product if you use the Thor library.
