As my video processing needs are usually pretty straight forward, I always end up finding inspiring solutions to my questions on this great forum and through tutorial patches and Andrew's recipes. But this time I feel confused with the many times discussed @capture concept.

I've been messing around with a nice little patch I found in this old thread :

https://cycling74.com/forums/falling-text-symbols-need-help

The idea is to use jit.gl.text2d and jit.iter to create a "text rain". It's working perfectly fine but now I wonder how it would be possible to capture this text rain to a texture so as I can include it to a slab processing chain and play with it just like any other source.

Pasted below is a modified version of the original patch to explain my point. I used @capture attribute and applied a texture to a videoplane but the rain effect then isn't displaying and only one character appears…

I feel there's some basic rendering concept I'm not quite getting right but I can't figure it out… My guess is that the jit.iter thing doesn't make it to the texture object and my brain just refuses to understand clearly why…

you will probably have more success capturing your scene using jit.gl.node.

i've modified your patch slightly to use this technique. take a look:

I recently had several occasions to read your various posts about jit.gl.node and other max6 objects that seem to make a lot of gl-world stuff much simpler. Unfortunately, I can't afford an upgrade right now… In the meantime I'll check this out on a max 6 demo somewhere.

But if someone out there has figured out a max 5 solution to a similar situation, I'd be curious to have look at it.

Thanks a lot Robert !

the texture is readback from gpu to matrix, so it can slow down

Smart solution, thanks a lot ! I finally could find some time to give it a try. It indeed slows down my 4 years old macbook but still, it's interesting to know it is possible to get this to work. Thanks again !

I have problems to capture gl.objects with @automatic 0 with jit.gl.node. Here a simple example with the dancing sprites recipe. Is here something wrong with the rendering order?

capturing objects drawn in non-automatic mode, is currently not supported, as you've discovered.

thanks, wonderful! time to substitute some patches and send them in some jit.gl.pix objects...
