Motion vectors in SL

  • AKHmetgaleev ILdar

    Any chance to get motion vectors in shaders. Object motion can be computed and passed to shader in rib  exporting stage. But this isn't best way especialy  when you need per vertex motion. Do you plan to make it possible if pixie can't do this now.

      Just to confirm, you'd like dPdtime?

      Might be awkward for raytracing, but is in theory not that hard for the reyes hiders.

      Yes dPdtime. RiSpec p121 Table 12.1
      Will you add it in next pixie release?

        I looked at this last night and (whilst possible) it's not totally simple due to the order we execute shaders in and how we do motion sampling.  It may not be the next release I guess...
