Pssst... free LUT calc tool over here:

Assuming you haven't seen this.. it looks like cameramanben has done something really useful here: he's compiled a ton of research and written a JavaScript LUT calculator tool released under a GNU freesoftware license (I think this is about as free as it gets). This could be used for 1D shaper LUT's, or 3D LUT's with gamma/gamut baked together - if that's more your thing - and even custom code value ranges. I think you can upload a sample image too. I see an A7s profile as well as Rec2020 gamut, DCI-P3 gamut... it's on github. Online tool: http://cameramanben.github.io/LUTCalc/LUTCalc/index.html Link to browser based apps: https://cameramanben.github.io/LUTCalc/ Objective-C wrapper for MacOS: https://github.com/cameramanben/LUTCalc-For-Mac He needs a donation button somewhere.

Under the "preview" button http://cameramanben.github.io/LUTCalc/LUTCalc/index.html there's also a waveform, vectorscope, and rgb parade option. Cursor over the test image to get 10bit color values.
