spektrafilm tech discussions

gpus are such bandwidth monsters… but yeah, that’s one extra spectral buffer now. and while the memory allocator will alias buffers if it can… i don’t think that scales to very complex graphs.

yeah now the rgb → sigmoid spec is 3D → 3D so pretty unique of a mapping. using more coefficients and going to rgb i’d lose some definition, certainly. and upsampling i’m not sure makes much sense to optimise against rgb, i’d optimise it against spectral shapes directly. for those kinds of spectra i’d certainly expect some loss when going to rgb as intermediates. need to try and store these extra coefs with low bit counts. they normally don’t compress so well and need f32.
