Hi - This is what I am trying to do. I made the laptop in the macro course and want an animation to come out of the screen, the materials will change as it exits the screen. I have started with just a ball and playing with another with the hold out material. I can get the one on the inside to disappear into the hold out and then think maybe have the other emerge from the holdout in another render. The one on the inside is displayed as an image texture on the screen in the second render. Hope this is a clear explanation, going down many many rabbit holes. Any suggestions would be appreciated. Thanks.
You might want to use Boolean instead of holdout. Then you can animate the cutter to hide/show pieces and they only effect objects that have the Boolean modifier.
Hi Tanya,
That's a great idea!
My first thought here is, to use the Ray Portal BSDF, although I wouldn't know how (yet).
I think the problem, is going from 3D to 2D and the other way around. The difference in Shading would be of a later concern and is probably relatively easy.
So, thinking aloud, 3D to 2D, where have I seen that before...isn't that Rendering? Using a Ray Portal, couldn't we show on the laptop screen what a (maybe Orthographic) Camera sees? Maybe together with some cleverly placed Light Path Nodes, to decide whether we see the 3D Object, or the flat Rendered version?
Like I said, I'm not sure if this would work, but it would be the first thing I'd try.
You could also try and find how they did this in Hollywood productions (YT must have something....)
And of course see if Dwayne's idea works (might not be easy, when you get characters coming out of the screen...)
I'm thinking magic trick style. What if your laptop screen has real depth to it? And the objects inside are the real objects, and they just come out and it'll look as if it was a screen because it is a screen of a laptop. It'll depend on what's on screen and the type of shots, but it feels like it could be doable this way. The laptop would have to be head on, if you look it from the side it'll break the illusion.
Also if it's a flat screen on the laptop, I would scale and squash the objects near to zero and just animate their visibility into view as they pop out of the screen and un-squash and stretch out of the screen.
