The glAppGrapher is an interactive OpenGL-based debugging "watch window" that communicates with your program via Berkeley sockets. Its purpose is to simplify mondain tasks of debugging a physics engine or other 3D application. The program may work over the Internet or your LAN, and is supported in both Windows and Linux environments.
Kobldes makes it possible for the designer to model building information and uses POV-Ray for visualization. It is also programmed using the POV-Ray screen description language (SDL). The goal of is to create a fully functioning building information modeling and management tool for designing buildings. It currently allows the designer to accomplish basic tasks with building components such as building levels and spaces in the process of solving design problems. In the near future, it will compute and make available information about the building such as sizes/volumes (such as an area for painting in a particular room), requirement checks (e.g. spatial conformance), and Property checks (e.g. calculating the solar savings factor).
