FFGL Delay/Buffer Effects

I've been hoping for some time that some kind of delay effects would surface for Resolume 3.x. I often found these effects great for experimentation (and inspiration) in Resolume 2.x. I'm aware theres a FF 1.0 wrapper but I'm under the impression that this isn't possible on a Mac, as these effects were all compiled for Windows.

Now its a while since I used Resolume 2.4, but theres still no equivalent to the following effects, some of which are sorely missed:

time slide
delay RGB
delay and slice
delay film
Video Sampler (sp.?)

(I can't remember which of these effects were the best; some of them were very similar).

I've been able to get a "slit-scan" style effect (similar to delay and slice and timeslide) in 3.x by placing Feedback above the layer I want to affect and changing the blend-mode to wipe-left @ >0.75 (or wipe-up/down/right). In addition, if I animate the AnchorZ parameter on the layer below and limit it so the image is being slid across the left side of the frame, I get a kind of smeared/delayed version of the layer below scrolling across.

This is quite cumbersome of course. Does anyone know of better way to achieve these effects? Is anyone working on something or have any hints they'd like to share with me?

On an unrelated note, would an effect like this ever be feasible in FFGL???

PS, I'm writing this in work so my terminology might be wrong. Another thing which I've just remembered - is there a way to animate a parameter to MouseX or MouseY?

Thanks for reading.

yeah, +1 for buffer and delay :)

For delay buffer many videomemory is required, and it a deficit always.
But I implemented delay buffer in a IRCosmicPack (irworkshop.com).

And in the near future I will make a new package of effects, including the buffer delay.

Looking forward to new effects Ivan!

So am I right in saying FF 1.0 effects used only the RAM, while FFGL effects may use only the video memory?

I recall getting good performance from these effects in Resolume 2.x. Are they far more difficult to implement in FFGL? Will we ever see that kind of functionality again?

Pretty much, it's actually computer processing power (CPU) vs graphics card processing power (GPU), but you get the general idea.

If you could wrap your head around FF, you can grasp FFGL as well. In general, I don't think it's that appealing to programmers to rewrite something they already did, and the effects would have to be rewritten for the new specification. But FFGL is relatively new, give the scene some time, and interesting effects will pop up (like Ivan's above, and also the cool stuff that Matthias is doing).
