  • $\begingroup$ I was looking to create something like this vimeo.com/125511537. Didn't know how it's done. I kinda assumed the workflow I mentioned in the question and hypothesised that's how it's done. $\endgroup$ Commented Apr 11, 2019 at 6:44
  • $\begingroup$ As far as you have the depth map, I guess the shadow in that video is rendered with shadow mapping. The main object may be rendered in many ways. The easiest technique (if scanner resolution is not too high) consist on generate a quad per pixel in your depth map and set the axis coordinate according to depth values in the vertexes. If you want to do it in a more efficient way or scanner resolution may vary with time, the quads can be generated by a geometry shader from a more basic mesh. $\endgroup$ Commented Apr 11, 2019 at 10:50
