3D lut size and bit depth questions

Est <rame...@...>

Hi All,

I recently started using OpenColorIO and I have some questions:

In my current code, I'm using a 32x32x32 lut, just for the display,
not for processing.
Is it a good size? How do you choose a 3d lut size?

In the spi-cg config, what's the difference between vd16 and vdf?
I see they have the same parameters and lut. The only difference is
bitdepth. I haven't read all the code yet but it doesn't seem that
the bitdepth is used when converting colorspaces.

Thank you.
