This is a 3D, localized wind demo—not a game.  It is an independent project that I created for the purposes of generating rolling meadows; it would be great to pull the physics into a game.  The cell-based simulation controls and maintains itself, dynamically changing wind flow based on the following: pressure gradients, wind-terrain collisions, and ground temperature.

CONTROLS
1                      Toggles Wind Arrow Visibility
2                      Toggles Cell-Based Grass Blade Visibility (Used for Interpolation)
3                      Toggles Interpolated Grass Blade Visibility (Interpolated from Above)
P                      Pauses/Unpauses the Simulation
Space              Steps Through the Simulation One Frame at a Time
A                     Move Camera to the Left
D                     Move Camera to the Right
W                    Move Camera Forward
S                      Move Camera Backward
R                     Move Camera Up
F                      Move Camera Down
Q                     Rotate Camera to the Left
E                      Rotate Camera to the Right
T                      Rotate Camera Up
G                     Rotate Camera Down
J                      Creates a Very Small Gust of Wind from the Left
L                      Creates a Very Small Gust of Wind from the Right
I                       Creates a Very Small Gust of Wind from the Top
K                     Creates a Very Small Gust of Wind from the Bottom
