videowall on curve in 3d space

[Steve Roberts]

Make the videowall in a comp, then drag that into another comp and apply the CC cylinder effect?

Or, with separate layers: make a bunch of 3D layers, with their anchor points set back in Z-space. The setback should be equal to the radius of the imagined circle. Make enough of these, and rotate them around Y so you get a videowall which is part of a faceted cylinder.

Does that make sense?

By the way, for the CC cylinder version, the videowall should be set up in a comp which is twice as wide as it is high, but the screens should only take up part of the width of the comp … otherwise they’d make a full cylinder. You see?

Yes makes sense.

What I am getting at is auto orienting to a path in z space…..just in case I wanted something more irregular like a s-curve (from the top cam angle) for the video wall follow when it moves….

You will have to use Zaxwerks Invigorator for the “S” shape. Or a 3d program.

or place them by hand you can use 3d assistants for stuff like this
make an line of the video screens and then align them however you like, an S C a U a J etc etc

3d assistants will make cubes of planes/solids/comps in AE

Hmm … you could try building the wall in a comp, then dragging that into a comp and applying card dance. You’d need to also create precomped gradients that represent the amount of Z-displacement and y-rotation of your screens.

I’d try creating a ramp gradient (left-to-right) then applying the curves effect. Adjust your curve so it sort of looks like the curve of your wall. You’ll have to experiment with the ramp comp window open and the card dance comp window open at the same time.
As for the rotation … that’s trickier. You’d need a different gradient for that.

Or you could download (buy) trapcode’s Echospace plugin and see if that does it for you. 🙂

thanks guys.

3d assistants seemed to do the trick.
