Modelica3D is a lightweight, platform independent 3D-visualisation library for Modelica.
The original version of Modelica3D comes from https://mlcontrol.uebb.tu-berlin.de/redmine/projects/modelica3d-public. That project has not been updated in while and does not work in OpenModelica. This fork works in the Modelica Standard Library 3.2.1 (MSL 3.2.1) and also no longer needs a patched standard library.
