Leadwerks Engine is a 3D engine for rendering, sound, and physics in real-time games and simulations. Leadwerks features a unified lighting system with dynamic soft shadows. The lighting system removes the need for any pre-processing or compiling; scenes can be edited in real-time, and the results are instantly visualized, significantly streamlining the development process. The engine is offered as both a dynamic linked library (DLL) and BlitzMax module. Official support is included for C/C++, C#, and BlitzMax, as well as community-supported extensions for Delphi. As of 9/2009 a single user license is $150. There is a free downloadable evaluation kit.
