1. Driving Land Vehicle Game Programming Fall 2013

2. Content Kinematic maneuver Dynamic maneuver

7. Remark No dynamics Position of vehicle implicitly defined in modelview matrix Difficult to compute bounding boxes

8. Dynamic Maneuver Assume the vehicle is a particle The power and angle of thrust can be controlled Drag is always opposite to the velocity (no drag is motionless) Integrate equations of motion by Euler’s method thrust = Power Rot (  ) v x drag = -k v  force = thrust + drag

9. Using Virtual Keyboard UP/Down: increase/decrease power by a ratio Home: start engine with power = 1.0 Space: stop engine with power = 0.0 Left/Right: turning (next page) Force_gas: the thrust force exerted by the power

10. Engine Force Power: controlled by up, down, home, space Theta_thrust: controlled by tank orientation (theta), left and right

11. Tank Rendering pos  vel Force_gas x z
