1. Cycle Sim A bicycle ride using OpenGL and an exercise bike. John Aschenbrenner Phil Thorpe

2. Project Objectives Exercise Bike Provides User Input Smooth Animation Expansive Environment Attractiveness

3. User Interface Bike Placed beneath desk Pedaling controls forward movement Joystick or keyboard on desk used to steer

4. User Interface

5. Sensor Connections

6. Sensor Placement

7. Performance Specs Maintain frame rate >=30 fps Sensor able to cycle 300 a minute  200 ms, Our sensor is rated at 0.5 ms Update speed at least 30 times a second Travel in a straight line for at least 60 seconds

8. Software Flow Chart

9. Communication Protocol

10. Collision Detection Array defining object boundary locations Program iterates array to detect collisions Not highly processor intensive  Supports 25,000 to 50,000 array elements

11. Object Models All Models built in OpenGL More efficient geometries than modeling programs Slow and difficult to create complex models.

12. Problems John’s video card is broken Modeling is time consuming Joystick polling not guaranteed at regular intervals

13. Project Timeline

14. Cost Analysis

15. Conclusion Predominantly Software Simple Hardware components Hope to have a basic functioning system by January
