Hi. I’m super green to Touch, but working my way through tutorials and videos trying to find my feet. I’m coming from a Resolume background and I’m currently trying to work out how to output from here through an output pixel map for multiple LED screens, like you would do in Resolume etc, but I’m struggling.
I’ve found many focused on pixel mapping fixtures, but nothing specifically for LED screens. Are there any tutorials on this subject that I might have missed?
Thanks, Ed
If you just mean slicing and positioning parts of your final output into blocks to match a raster that an LED Wall processor is expecting, yeah it is totally do-able.
You might look into some of the processes used in projection mapping, but mostly it usually involves (at it’s simplest) using a bunch of Crop TOPs and Over or Composite TOPs to cut up your final output and then reassemble it into the shape of the raster. You could also crop a bunch of shapes and then create a bunch of Container COMPs and then have an easier time adjusting those in how they lay out in your Perform Window.
A more advanced version would be to construct a sampling map of red/green gradients (32 bit) and use the Remap TOP to do it all in one step, but that’s a bit hard to explain quickly.
I feel like there may have been a TOX or some GLSL code (for a GLSL TOP) out there somewhere that has a simple UI for doing this to a limited number slices, but I can’t find it with a cursory search.
@NEICO How did you go with this? I am currently trying this.
I’m also interested in this. The Crop/Composite approach seems totally doable. But I’m up for a challenge.
