LIENODING X Animation Nodes for Realtime Tracing & Tracking of Positions as Curve
In this episode, I am showing you a simple node tree setup using Animation Nodes in Blender that enable you to track and trace a position of 3D object in time, store that data and generate Curve on the fly.
Despite its simple setup, this kind of node tree is quite sophisticated and uses python setattr as Expression node. Original node tree setup was suggested by Omar below.
