We present a system for interactive animation of trees in a wind-field. Wind forces are simulated by Navier-Stokes equations, solved in real-time using multi-processor CUDA architecture. The dynamics of the tree is also modeled and simulated in real-time using elastic body physics on CUDA. Due to the animation being entirely physics based, it is straightforward to design wind-fields by adding artificial sources and obstacles and have the animation respond. By using an efficient parallel algorithm we are able to animate over a hundred trees in real-time. We demonstrate animation of a forest of trees in a variety of wind conditions under interactive control of a user.
