I thought I could easily knock together the equivalent of the area chop in Houdini but got a bit bogged down. Just the simplest case accumulation is what I’m after so I thought I could pull the value of a channel from the previous timestep using the feedback chop and add the absolute of the current and previous values to get what I want, a simple accumulation. No joy yet… I bet I’m missing something really obvious, any takers?
darn… spoke too soon! I figured something like $V+ic(0,$C,$I-1) would work too but no banana. Tried the trail approach too, I’ll try to get a simple example together!
I misread your question. Thought you were trying to implement it in Houdini.
The Area CHOP is alive and well in TouchDesigner, but has been renamed Speed CHOP.
