Glen Lenker and Benjamin Nuernberger both worked on this project in collaboration. Below is a breakdown of how we split up the work:

• Ben: There must be at least 10 pins and 4 walls for your pinball machine.
• Ben: The required pieces must be drawn using simple polygons (triangles or quads), specifying the normal for each. You may draw other things (in- cluding the pinball) using the convenience functions provided in assign- ment 1. Also, you may fill the top of your cylinder with a sphere, so that when viewed from the top it can be seen easily.
• Ben: When ’n’ is pressed, drawing of the normals should turn on and off
• Ben: All normals should have unit length and be located on the center of the polygon they correspond to.
• Glen: The initial direction and location of the pinball should be chosen randomly at runtime (unless you specify otherwise in the extra credit).
• Glen: When the pinball runs into a pin or a wall, it should reflect off of it and continue along.
• Ben: Pressing ’v’ should toggle between viewing modes.
• Ben: The first mode should be a static top-down orthographic view of the scene.
• Ben: The second mode should be an animated perspective flythrough which forms a complete loop and repeats. The path of the camera is up to you, but it must turn 360 degrees around the scene and zoom in or out at some point during the process.
• Glen: The third mode should be a first person view of the ball as it moves.
• Glen: Pressing ’s’ should draw a wireframe outline of the viewing volume used in the third mode (in other words, the viewing volume of the pinball).
• Glen: Pressing ’r’ should reset the process, starting the pinball somewhere else in the scene (randomly chosen).
• Glen: When resized, the aspect ratio of the objects in your scene should stay the same (no stretching).
• Both of us: All code should be in one file, called pinball.cpp

We also added some extra credit as follows:

• pressing 'o' or 'p' will increase or decrease the pinball's speed.
• pressing 'x' will change the pinball into a robot.
• pressing 'f' will cycle the flythrough view modes between 3 different views.
• pressing 'h', 'j', 'k', and 'l' will move the view around in the first view.
