Force field

I started by using an idea of a forcefield like collision boundaries which moved the tree depending on where the object hit the tree. This was alright, but it wasn't very realistic as it had no realistic movement

Fractured rigid body

I decided to use a mix of fracturing the tree into branches that would be able to fall apart using constraints. It performed better than the force field, but the rigid body was unreliable and would often become erratic. However, this is still a great option that i could have used

Final

My final dynamic based tree consisted of a lower poly version of the tree that connected to individual parts of the tree. This allowed for great performance while simulating as the pieces are large and have big hitboxes.

Dynamic vegetation

While creating the tree’s I also made some dynamic vegetation which moved with objects as they moved past.
