I'm currently looking at moving our existing color pipeline tools over to OCIO, and I'm wondering if anyone can see a place for such a feature.
In our current setup, some of our log to lin conversions cannot be adequately expressed via a 1D lut, and for grading operations the changes caused by interpolation are too great.
I'm proposing to write an Expression Transformation, which would allow us to express these transformation operations via a string, and evaluate them using exprtk or a similar library.
Has anything like this been proposed before? Does anyone have any thoughts? I'm hoping to knock up a proof of concept over the next few weeks.
