I think I figured out a clumsy way to do this with the C++ API. Stand down!
From: "Sloan, Blake" <bsloan@...>
Hope you’ll forgive this not-quite-developer question: More than a year ago I tested the slow 3D LUT inverter in the then-provisional OCIO 2.0. I cannot remember if I had tested it as an option in ociobakelut (-invlut option does not seem to accept 3D LUTs), the python API or a few lines of c++ added to my OCIO 1.0-based, home-grown 3D LUT inverter.
Is there an example of this anywhere in the new release? Is this my payback for not contributing a single jot to development?
Thanks in advance!,
