I have a hologram like effect in the Cycles render engine. And so far I'm satisfied with the results. enter image description here

And my node setup is this ("Emission" shader and "Transparent" shader are mixed together by a "Layer Weight" node in the "Factor" value of the "Mix Shader" - enter image description here

However, is there a way to create those transparent lines that when animated go upwards like in many sci-fi movies? Something like this - enter image description here

  • $\begingroup$ David's answer works for me now, but lets say that the object was rigged and animated, is there a way for lines to travel at the direction of the Z normal of some projector of the hologram regardless of the animation of the object? This is what I mean by a "projector" (the sphere like object is projected by a projector [the object underneath it]) - digibuzzme.com/wp-content/uploads/2013/08/… $\endgroup$ – Vladimir Sep 12 '14 at 17:45
  • $\begingroup$ Lets say that the floor in the first image above is the projector of the hologram. Is there a way for the lines to travel at the direction of the Z normal of the floor regardless of the animation of the object? $\endgroup$ – Vladimir Sep 12 '14 at 17:49

Cycles nodes
I used a Checker Texture to make the lines, adjust the scale to make the thickness of the lines you want. The Mapping node's Scale along the Y and X to 0, stretches out the checker texture to make it a line. Then the Location along the Z is animated to make the lines move. Replace the two Emission nodes for your hologram shader.

  • $\begingroup$ Thanks. I tried something. Is this ok, or I'm missing something? - pasteall.org/blend/31537 $\endgroup$ – Vladimir Sep 12 '14 at 15:23
  • $\begingroup$ Also if possible, is there a way for the transparent part to be not completely transparent? $\endgroup$ – Vladimir Sep 12 '14 at 15:27
  • $\begingroup$ @Vladimir pasteall.org/blend/31538 take a look at what I did to the nodes. $\endgroup$ – David Sep 12 '14 at 15:42
  • $\begingroup$ Thanks (pretty easy actually). Just one last thing - Lets say the hologram (monkey) was projected by the floor underneath it, is there a way for the lines to be aligned with it (the lines to move upwards according to the Z normal of the floor)? ('cause that's why I needed the effect in the first place) $\endgroup$ – Vladimir Sep 12 '14 at 15:54
  • $\begingroup$ sounds like you would want to UV project from View (Bounds) to get all the UV aligned, then just stretch out the texture again. $\endgroup$ – David Sep 12 '14 at 15:55
