Title:	DLR Visualization 2 Library - Real-Time Graphical Environments for Virtual Commissioning
Authors:	Sebastian Kümper, Matthias Hellerer and Tobias Bellmann
Abstract:	In this paper, the next generation of model-based visu- alization is introduced, the DLR Visualization 2 Library. This new real-time graphics environment for Modelica is equipped with a state of the art engine for physics based lighting calculation and high-definition render quality, si- multaneous visualization of parallel running simulation models, new features like a modern streaming interface and a new, cleaner library structure. It enables the user to create graphical real-time environments for virtual com- missioning of complex systems of systems and imaging based sensors. Some applications, as for example depth- camera data generation or rendering of point clouds or vectorized flow visualization are demonstrated in the use cases section of this paper

Title:	General Purpose Lua Interpreter for Modelica
Authors:	Fabian Buse and Tobias Bellmann
Abstract:	The application of simulation in the development of complex systems becomes more and more important. Modeled systems often are comprised of mechanical, electrical as well as software systems. It is usually not possible anymore to evaluate a systems performance without considering some higher level logic. Scripting languages such as Lua, are often well suited to implement these logic elements. This paper shows the integration of the Lua interpreter into Modelica, and gives examples how the library can be used to help with the simulation industrial robots or in the development of a planetary exploration rover in the MMX Mission.
