OpenGL presentation at PyGTA went alright, but it went *way* over time (2.25 hours) and that was without any particularly involved demos or the like.  Then again, wasn't really attempting to keep to any sort of timeline.  Can likely cut out much of the political stuff, and can go faster on the shader theory (I'm ...

As I've been working on the OpenGL presentation I've run into this issue a couple of times... much of the overhead in PyOpenGL 3.x's array-handling could be eliminated if we didn't allow for copying data at all when passing in array values.  That is, if we were to always require that the client-passed value be ...
