Map texture in a curved LED screen

[Gerson Martinez]

I´m trying to draw a concave LED screen backdrop in a stage with a texture mapped on it, after a while trying to make it work I just solved it making multiple arrays of 1x5 modules and giving the angles one by one.

 

 

How can map a a single image to the whole screen?

If you have the Landru Tools version, there is an additional PIO to map a texture across multiple Instances. Otherwise, you might just create a curve, tapered extrude, and use that for the image.

FYI, the ReShaper PIO help to layout the array.

As @Kevin Allen said, users of the Landru Design versions of the tools have access (by asking) to a VERY BASIC VideoTile Command.  Here is a simple demo using 174 tiles:

Use a cheat? Try the Shell tool in 3d Tool set. Shells comprised of several source surfaces texture as a single surface, in Plane Mapping.

 

For safety, dupe the whole set of screens. Offset or move to a new layer.

 

Engage the Shell tool. Set the thickness pref to something small - eg 5mm or 1", or . . . (adjust later as needed)

      Shell can grab many types of surface, even surfaces contained in groups or booleans.  

Click each screen with Shift key held until all screens are highlighted.

Release the Shift Key. Click the green rectangle (upper left in Mode bar).

Note: The original surfaces will be consumed by the Shell (hence the dupe).  To retrieve them, Ungroup the Shell.

 

Apply texture to the shell via OIP Render tab.

Mapping = Plane

Scale via slider or numeric as needed.

Adjust texture position via Attribute Mapping tool. or numeric offsets.  Front view best.

 

Move the shell to match original position of the screens.
