3D LED Mapping Twisted Tubes with 3D Objects

Hello,

I am currently working on 3D pixel mapping and have a project in which I want to map several interlocking rotated tubes.

Normal mapping with 2D content works fine. But now I would like to have the possibility to use the three-dimensional space and simulate several 3D objects in different colors on the object. In other words, a sphere with a diameter of about 1/3 of the largest tube should move in the middle and at the same time several LEDs should light up rhythmically at the ends in different colors. Or another example, a particle system is attracted by the center of the tubes and runs through all levels.

I’ve already looked through all the tutorials and can’t find a good solution. I’m sure for some people here, the problem would be solved in just a few nodes … unfortunately I haven’t been doing pixel mapping that long myself.

I was able to display a moving sphere using the SOP group, but I cannot place a second object with a different movement in a different color …

Hi @N1nsch4,

there are various approaches to this but all depends a bit on your physical setup and what kind of objects you would want to move through the volume.

One approach could be using @tekt’s RayTK

You can always share your current progress which let’s people explore your issues and offer particular help.

cheers
Markus

This tutorial covers using RayTK to produce colors for points, which can be used to map to LEDs.

That is very cool, thank you both very much, I will use it to realize my project. :smile:
