       | I have tried meshroom too, the result is equally bad.

       | how much memory does it typically require?

         | demonstrations show only static objects.

       | Oooh exciting! NERF is a very interesting technique but last I
       | heard rendering was taking 20 seconds per frame. This looks
       | great. It says it can do 150 fps by translating the NERF to a
       | more renderable format, which makes sense.
