Soulthought

I'm working on an LED installation and I'm running into the boundaries of my knowledge of Max. Attached is some code using simple paintrect messages and a video of what this looks like on an LED installation.

What I'm trying to do is to send a single-rowed matrix, chop it up and duplicate it in order to achieve the same effect as my simple paintrect messages. I'd like to be able to use gradients and whatnot. Can someone take a look and point me in the right direction?

I am unclear what you question is. Would you restate your question with a goal?

I looked at your patch. It runs and I see white lines in the jit.pwindow.

Meanwhile, Max6 has jit.mgraphics which allows you do a lots of 2d drawing.

And there are many objects which allow chopping, scaling, repositioning, etc. of matrices.

The jitter tutorials cover a lot of these. See jitter tutorial 13-18

Does something fail with this patch?

The patch doesn't fail, it works as I would like. It's just limited because it's only capable of one color and no nice gradients :(

Goal: Send a jit.gradient (example green to blue) into a patcher. The gradient should be cut / duplicated / repositioned so that it fits the LED installation.

If the gradient was white to white for example, then it would look exactly like the patch I posted above.

I... was not aware of jit.mgraphics, I never really looked at what was updated in Max6. Awesome addition, seems to be pretty poorly documented though. Are there any good learning resources for it?

If that's all you need, then use jit.gradient and the tutorials I listed to do your cut/repositioning.

For mgraphics, I found the help patcher useful. And on the ? tab of it, linked is the Mgraphics quick start guide. The js commands can generally be used with Max messages too.

This tutorial was pretty helpful explaining everything for a beginner
