Animation of BouncingBall3D fails to visualize in OMNotebook
Animation of BouncingBall3D fails to visualize in OMNotebook
Hi,
I am trying to learn 3D animation with Modelica.
As entry point I am using the "OpenModelica Users Guide Version 2012-09-14".
The example I am trying to run is the BouncingBall animation example from section 3.4.2 of the attached userguide.
For some reason the last statement in OMNotebook i.e. the visualize(BouncingBall) just returns false.
This leaves me somewhat puzzled on what to do? since the BouncingBall is a write off from the userguide and since it compiles and simulates.
Hope someone can help me on what I am doing wrong :-)

Re: Animation of BouncingBall3D fails to visualize in OMNotebook
Hi,
It seems we're missing the OMVisualize executable from the OpenModelica installation.
I'll talk with some developers to add it to the next nightly builds.
Cheers,

Re: Animation of BouncingBall3D fails to visualize in OMNotebook
Hi,
I don't know yet if we will make this available as we do have another way
to visualize 3D models that we are working on.
The new way is via Modelica 3D and ModelicaServices
which is more close to Modelica "standard" for visualization.
The old visualize command is based on SimpleVisual which is
not "standard" Modelica visualization. We will have to take a decision
about this. I will let you know how things develop.
If you want to play with visualize you can install an older OpenModeilca
version, i think 1.6 was the latest that had this functionality working:
https://build.openmodelica.org/omc/buil … /releases/

Re: Animation of BouncingBall3D fails to visualize in OMNotebook
Hi,
I now included OMVizualize in the latest nightly-build for Windows:
