The explanations about omnigraph nodes on the Omniverse extension and Isaac Sim API websites are very simple, only describing the input and output variables, with no examples or detailed descriptions of their functions. It is quite difficult to program with omnigraph.
Additionally, Omniverse is not open source, so how the underlying operations of Omniverse, such as the coordination between physics stepping and rendering stepping is unclear. On which thread user scripts or graphs execute, and how they affect the simulation process are also unclear.
Is there any detailed documentation on this。
