Castle Game Engine is a cross-platform 3D game engine written in Object Pascal. It includes a flexible system of 3D objects, with out-of-the-box levels, items, intelligent creatures, and more. Rendering and processing of 3D models in X3D, VRML, Collada, and other formats is implemented. Many graphic effects are available, including shadows, bump mapping, shaders, mirrors, and screen effects.
The Gluon project is an open framework for creating and distributing games, supporting the flow of the idea all the way from the author to the player of the finished game. The current goal for the first stable release is to create games using 2D graphics. The reasoning behind this is that the niche for this type of visual is very large and so far untapped by specialized tools. In the world of 3D games there are solutions such as Unity3D, which provide a distribution system, but in the 2D game development world there are no tools to provide a complete ecosystem for creation, distribution, and feedback gathering. The three main audiences of Gluon are game creators, game players, and application programmers. Each of these are a user of one of the tools.
