LED Screen Simulation in Stride

vvvv gamma question
1

Hi everyone,

I’m trying to simulate an LED screen in Stride, and I’m stuck.

In principle, I’d like to map a texture onto individual LED pixels. My idea is that there should be a direct correspondence between the texture UV coordinates and the physical positions of the LEDs on the screen.

My first thought was to use Pipet, but I haven’t been able to make that work. At this point, I’ve reached the limits of my knowledge.

The LED screen is expected to be fairly large, so I’m looking for an efficient way to handle the data and render the result.

Has anyone done something similar or can point me in the right direction?

Thanks!

With your screen size math…

Yep, that works! Great, thanks for your help!

If it’s only about the simulation and you don’t actually need the color values on the CPU you can avoid the expensive readback by using the Sprite material extension that comes with VL.Addons.Stride for example.
