Fusee aims at becoming a multiplatform 3D realtime engine with a strong emphasis on content transformation and manipulation. Fusee is written mainly in C# and can be programmed in C#. Fusee builds bridges to make your code run in environments that don't support C#, like Content-Creation-Software, C++, Plug-In-APIs and native HTML5/WebGL Javascript code.
