1. CS0007: Introductory Programming Rotational Motion

2. Motion Motion of an object is relative to the orientation (front) of the object the center of the object

3. Center of an object An object is positioned in the world around its center. The center of an object can be: At the center of mass, or Where it stands on the ground, or Where it is held or connected (a hinge joint)

4. Dimensions and Orientation A 3D object has 3 dimensions height, width, depth orientation

5. Motion Motion of an object is relative to its orientation its center

6. Translational Motion Change of position of the entire object in the world The direction of translational motion is stated relative to the orientation of the object. Objects are ego-centric, motion based on orientation of the object Six possible directions move left right up down forward backward

7. Changing Orientation up right forward up right forward

8. Demo: Mouse Control Toolkit To reposition objects in the world, use the buttons in the mouse control toolkit

9. Demo: Translational Motion Six possible directions move left right up down forward backward

10. Demo: Pull-down menu methods In setting up a world, can be used to resize an object precisely position an object and it's subparts

11. Rotational Motion Rotational motion occurs around the center (pivot point) of the object or subpart of the object. Directions are divided among two instructions: turn forward, backward left, right roll left, right No up and down directions!

12. Rotate? Rotational Motion Note that the movement is around the center of the object. turn forward orientation changes roll forward orientation remains the same

13. Aeronautical Terminology Pitch: turn forward or backward – rotation is like a hinged lid on a box Yaw: turn left and right – rotation is like a door on hinges Roll (a.k.a. Bank); roll left or right – rotation is like a doorknob
