World Frame

Post by Johannes Hänlein » Sat Jun 13, 2020 4:32 am

Hi,

in the OpenSense tutorial (https://simtk-confluence.stanford.edu/d ... -topofpage) I read that the rotation of the world frame in OpenSim is Y up and Z to the right, but I wonder whether this is a right- or left-handed coordinate system? So points the X-axis in- or outside?

Thanks for your help!

Johannes

All coordinate systems in OpenSim are right-handed.

You can find which color corresponds to each direction by hovering over the frame icon in the top left of the visualizer window:
