Due date: Thursday, March 3.

Download the modified version of the object.c combined with the trackball.c and test it. The Makefile has been modified to include this new application with the command "make object".
my_object.cc
trackball.cc
trackball.h
Makefile

Ex. 1 Modify the interface to add the following items:

• The right mouse button should translate the object over x and y or a combination or them instead of quiting the application. For this you need to declare the translation array again as extern in trackball.cc to be able to modify it in the mouse functions.
• Add the option "q" to the keyboard function and make it exit the application.

Ex. 1 a. Write a function to create a tea or coffee cup using any GL, GLU, or GLUT commands that you think appropriate. Here is a suggestion of what the tea cup could look like (but you don't have to follow this).

• a disk of radius 0.2,
• a cylinder (truncated cone) with the base radius 0.2, the top radius 0.4, and a height of 0.05 (the 2 of them would make the plate),
• a cylinder of  base radius 0.19, a top radius 0.25, and a height of 0.1,
• a cylinder of base and top radius of 0.25 and a height of 0.3. (the 2 of them make the cup).

b. Add at least 3 cups to the scene and place them at positions of your choice on the table. Notice that the table has the z coordinate equal to 0.75. Use rotations and/or translations to place the cups on the table.

Ex. 2 (5 extra credit points) Add a handle to the tea/coffee cups.

Turn in: source code for both exercises (1 program) in electronic form.
