Subject: How to do a "holographic transmission" type effect?

I have a need for a a "holographic transmission" type effect.  Think Princess Leia in Star Wars saying "help me Obi-Wan" - that sort of thing.  

Not trying to mimic that exactly - really can be anything towards that, but essentially it's a holographic transmission.

Has anyone seen this sort of effect done in Poser?

I imagine there's a way to do it in Photoshop but before I go down the google-for-photoshop-tutorials route, I thought I'd ask.

Like this?

I set up a primitive cylinder as a light emitter and did the same thing with the figure, adjusting the transparency (particularly edge and fall off) to suit.

Yes, exactly - thank you.

That's a beautiful piece, btw.

Thank you!  I TRY to stretch my artistic capabilities. Sometimes I pull it off, sometimes I don't. My gallery is not exactly popular, but I'm here to learn and share what I know.  This particular technique came in handy for three or four renders I created to illustrate my fourth novel, "Ceremonies and Celebrations."  You can view my gallery and see more of my artwork here:

The attached image shows the cylinder settings I used.

Okay, here are the figure settings. Good luck to you! Show us your image when you're done.

That's a great image but...

One thing I've never liked about that effect is the figures look hollow.  So far, I've never found a way to make the figures see through but not hollow, as they would be in a projection.

It should be a simple matter of turning the transparency down on the figure. You ought to be able to get whatever effect you'd like. In the attached image, the female figure has no transparency on her at all, whereas the "guardian" standing over her is ever so slightly transparent, with the light emitter settings cranked.

See through, but not hollow

Transparency will always produce hollow. Don't use that. Use refraction, and make the figure invisible to ray tracing. See the linked thread for details.

 

 


Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)

Oh, that's even better!  Thanks, BB!

I love all the examples shown here and I am sure I can find a use for all of them.

 

Thanks so much for sharing.

 

 

I use Poser 13 on Windows 11 - For Scene set up I use a Geekcom A5 -  Ryzen 9 5900HX, with 64 gig ram and 3 TB  storage, mini PC with final rendering done on normal sized desktop using an AMD Ryzen Threadipper 1950X CPU, Corsair Hydro H100i CPU cooler, 3XS EVGA GTX 1080i SC with 11g Ram, 4 X 16gig Corsair DDR4 Ram and a Corsair RM 100 PSU .   The desktop is in a remote location with rendering done via Queue Manager which gives me a clearer desktop and quieter computer room.

Okay, I tried the refraction technique that Baggins Bill outlined and this is how it looks. The effect isn't quite the same, likely because in this image there isn't anything in the background to show through, other than the light in the cylinder.

This is illustrated by the fact that the fingers of the figure's left hand, which have hair behind them, look very different from the hand, itself.

I'm going to make some adjustments and try this again . . .
