The main problem seems to be renderer support and the lack of information on how to generate the needed subpixel mask from a raytracer. Do you know if there was any advances in that area?

Does it just resample using the "closest" pixel? It's well known how to combine multiple non-overlapping pixels into a single depth list -- that's what renderers do to turn subsample depth lists into pixel depth lists for deep output. I would assume that a filtered resampling boils down to roughly the same thing (with adjustment for the specific pixel weights). Though I don't pretend to understand what artifacts would result from filtered resampling of a depth image in this way.

There is deep transform in Nuke, but it does not do any filtering and i am not sure there is a meaningful way to do that.

I guess it's theoretically possible, though you'd need to do a little math to figure out the right way to combine partial/filtered pixels, where each "pixel" is a list of depth+alpha samples.

If my B image is a different resolution than my A image/the pixel count is different, it would be nice to still be able to merge them together. Thanks!

I see in the docs that there is support for reading and merge deep pixels. Is the expected workflow for all deep images to loop over every pixel? Is there a function I've overlooked that might do a deep merge for all samples in the image? Wouldn't this mean that it's essentially single threaded to do a deep merge in python without setting up the threads myself? Thanks!
