I’m trying to animate a (crossed) four-bar linkage to emulate a knee joint.
I had a look at the scissor arm tutorial, but it’s not fully representative as it seems.
In a four bar linkage, apart from the basic link (the one being fixed), all other links and hingepoints are moving and their movement is being determined by the other links. So I have no idea how to set the thing in motion with something that can be independently defined.
Example of a crossed four-bar linkage:
Anyone has an idea or an example of how to approach this?
