Hi there, I've been trying to get a version of jit.slide working in jit.gl.pix so I can have independent control of 'slide_up' and 'slide_down' for a blur effect.

So far I have worked out how to do the blur sending the texture out, capturing it and mixing it back in. I thought I would be able to split the attack and decay by using greaterthan/lessthan to compare the input and captured texture. (I believe sending the texture out and capturing it adds a single frame delay, is that right?). I'm not getting anywhere near the desired effect though.

I was also wondering if there is a way of delaying a texture by longer than a single frame, I have tried speedlim and pipe to no avail.

I have attached an example patch to show where I'm at so far.

Why not use [jit.gl.slab @file tp.slide.jxs]? It's already done for you...

Thanks for the tip. I guess there are a number of reasons. Mostly so I can better understand the concept, so I can tweek it (I have more experience with Gen stuff than java). I've had a look at the tp.slide.jxs code to try and decipher how I might do this in Gen. Still not quite getting it though. Any further help would be great.

Just figured it out with a little help from the Gen~ examples.

i believe you can simply your patch even further:

Aha! Thanks Rob, that's much neater. All of this videoplane and node stuff made me forget about the slab.

Do you know how to make a delay longer than 1 frame in GL? That's the only thing I'm still struggling with at the moment.

it's a little tricky. i made this wiki page to describe the process:

Wow thank you Rob. I was half-expecting it was going to be more difficult than simply shoving a [pipe] object in there. I'll give your patch a close look and try to soak up all the knowledge.
