The Drag[en]gine is a fully customizable game engine and game development environment designed with modularity and extensibility in mind not requiring expensive licenses.
Shows solid and transparent shadows for Point lights. Uses cube map shadow maps. Currently uses non-depth cube maps ( encoded depth hack ) to work on systems without GPU4 support. An extra code path will be added for true depth cube mapping ( as this is faster on GPU4 enabled hardware ).
very cool. :)
