Re: Tetrahedral is Best
Jeremy Selan <jeremy...@...>
So if you look in the aces configuration, you'll see there are two .ocio files. config.ocio and config_1_0_3.ocio. config_1_0_3 explicitly specifies tetrahedral interpolation for the rrt 3dluts. The reason we havent chosen to roll that into the normal config.ocio is that tetrahedral interpolation was only added in 1.0.3, and I dont want to leave those folks locked off on prior versions (such as nuke 6.3v8) with configs that dont load. (If anyone has a better idea on how to approach this, please let me know).toggle quoted message Show quoted text
But this does raise the question, of what should OCIO::INTERP_BEST do? Currently it defaults to linear for both 1d and 3d luts. It would be a one line change to default BEST to tetrahedral for the 3dlut case.
In peoples experience, are there ever cases where trilinear is preferable to tetrahedral for 3d lut interpolation?
In terms of GPU tetrahedral support, we have some ideas how to add it in, and hope to explore them by the end of summer.
