Lag CHOP but in a TOP

I’ve made some progress in converting the Lag CHOP to a GLSL system. The idea is to store the chop value in the red channel and the one-frame velocity in the green channel. A more complete example would also store the acceleration in the blue channel. Would anyone like to make this example more precise? Suppose you changed the overshoot to 1.0 seconds. How would this affect the GLSL code? I was just making up formulas, so modify the shader code at will.

I think you can just use compositing of TOPs here. I’ve changed the feedback loop, now it composites a new image over, with 2% opacity. You can change the opacity in Level TOP to get faster/slower fades.

Thanks for checking out the file. I should have been clearer in my first post because my goal is for the two channels in “trail1” to be identical. The feedback system you’ve created is useful, but it doesn’t have the “overshoot” characteristic of the Lag chop.
