I have a question about the pixelmapping. I wanted to change the wiring of my pixels, but I can’t find, how to do that. I think, I will need to make seperated objects and then bind them together to one big stripe. But I don’t know, how to do that.
If you see, in the picture, the wiring was automatically made horizontal. But my wiring is vertical not horizontal, and the beginning is on the left top and goes in zigzag top to bottom, bottom to top.
It would be amazing, to get help, solving this thing. With the example file of the pixelmapping, I only see a circle but I don`t understand, how I could bind every pixel separately to a number.
To create the wiring in a zigzag pattern, I often use a Line SOP with the number of points of a vertical LED strip. Then duplicate the whole thing with a Copy SOP.
Do you have your file available as a reference and to better give you hints on a solution?
thank you for the fast reply. I used the copy SOP too, but in my case, it don`t make, what I want. But please, take a look yourself
You will see in the grid1 SOP. The picture above, was inverted, now in the project the beginning is in the bottom right. Which should be top left and vertical zigzag.
have a look at attached file: I’m using a Line SOP with 35 points and set the Point A and Point B parameters such, that it becomes a vertical line. This is then fed into a Copy SOP where each copy is offset by the amount 1/(copies-1) staying in a square. To make the points go “zigzag”, I also moved the pivot in y to 0.5 and flipped each line by scaling with the value of -1 on the y axis.
To see if it works I also adjusted the preview a bit to use points and the Line Render.
You still have to split the final signal to comply with the DMX standard and the available 512 values per universe.
this is so amazing. I think from your project, I could learn, how to do that and it`s very cool, to see, that this option is possible. Thank you so much, for your help and getting me closer to my project. I appreciate your share and explaining a lot!
Maybe not in the right thread. But would be possible to build with dots a custom wiring layout, like in xlights? Maybe you know it. Theres a possibility to wire a star or simlar things, which arent straight and setting every point where I want, to build a stripe out of the box.
very happy this helps.
Regarding your question about custom setups, there is always the theoretical option for these things to be done in TouchDesigner as you can build out whole applications. The option is not build in by default though.
For relatively simple shapes though, the procedural modeling tools available in SOPs should do the trick.
that is pretty cool. But I see, there is no simple way to do that, only with some “backdoors” but really nice work. I like the example which has a good description to make reverse engineering. Thank you for all your help and taking your time. Much appreciated
