  1. Driving Land Vehicle Game Programming Fall 2013

  2. Content • Kinematic maneuver • Dynamic maneuver

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

  4. 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 v drag = -k v x thrust = Power Rot (q) Sforce = thrust + drag

  5. 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

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

  7. Tank Rendering x vel q pos Force_gas z
