Getting data in and out of imath in python is *SLOW*. And yes, Python is a slow language, but that doesn't mean we can't kick it up a notch. Could I get some feedback on my proposals to speed things up?
https://github.com/openexr/openexr/pull/373 First is a PR with a *very* simple change that just exposes the memory address of the imath object. With a few lines of python code, you can read the c-data and re-interpret it in whatever way you want. https://github.com/openexr/openexr/issues/367 This is an issue where I described a more complex (and maybe more pythonic?) way of exposing the underlying data. Either of these proposals could remove the need for imathnumpy... Or imathnumpy could be replaced with a pure-python module that handles the more error prone memory mapping. Thoughts? ~T.Fox
