I’m not sure carrying wavelength or spectral info changes anything with respect to order of transparency.
It seems like OIT is kind of a misnomer when people are talking about deferred compositing. Storing data and sorting later isn’t exactly order independent, you still have to compute the color contributions in depth order, since transparency is fundamentally non-commutative, right?
The main benefit of spectral transparency is what happens with multiple different transparent colors… you can get out a different color than you get when using RGB or any 3 fixed primaries while computing the transmission color.
