General Description
The Rhino postprocessor is developed at the chair as a plug-in for Rhinoceros. More information about Rhinoceros is provided on their web page [1]. The visualization data of the respective inputfiles (out.georhino.txt , out.paramrhino.txt, out.paramlinesrhino.txt, out.post.res) can be manipulated.
Input Parameters
The block mainly consists of switches which can be set to a value equal 1 (on) or a value equals 0 (off).
