Get previous frame geometry

[Anonymous]

Hi guys,

Fairly new to bifrost. I have a an animated sphere thats been translated in x axis.
What I would love to do is basically have  the previous frame geo available to do some maths...(eg subtracting positions to get the direction vector)
I am kinda not able to get it through the feedback ports... I guess they work when the geo is deformed within the compound??(I might be wrong here..)

Any help would be super useful.
Thanks a lot 🙂

Here is the simplest way to gest previous frame data.

Im Very confused how do i get a compound node to do that?

its just a solver (feedback loop), so you can use the simulation example node. 

or you can create a compound, then you right click on the port and set the feedback port.
