This is educational toy. It allows you to build and control machine in 2D physical world. Uses Box2D for physics simulation, GPC for polygon manipulation and Qt for everything else.
UPDATE: DeleD is being remade at LINK as an online modeling solution.
DeleD is a game-orientated 3D modeler. It is aimed at 3D game development but can be used perfectly in other areas too, like educational services, prototyping or image creation. DeleD enables you to create static 3D objects and complete 3D scenes easily by manipulating primitives like poly-lines, cubes, cylinders and spheres. It unites the functionality needed to create great 3D scenes with a simple user interface. You can create and modify 3D objects and use various types of lights to bring your scene to life. DeleD comes with a number of import and export plugins for various well-known file formats.
