1. Hi Christopher, first of: I completely love this course. It is so perfectly executed! Thank you very much for all the hard work you put in.
    I have one question regarding this video (PTG03):
    I was trying hard to wrap my head around how in this example the simulated caches are read back before being fed to the opengl node. Is it that in this case the simulation is so fast we don`t really have to rely on the written caches and so the opengl node can run the sims again or am I missing sth here? I saw you demonstrating how to read back files in the next video but I`m still struggling to understand the whole data flow of TOPs in general. So many thanks again for all the effort. It ist very much appreciated.
