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. > On Dec 6, 2016, at 2:11 PM, Thorsten Kaufmann > <[email protected]> wrote: > > This is far from trivial.
