Sierpinski	Learn to use the basic drawing tools with OpenGL and GLUT. Use the keyboard and mouse for user interaction.	Specify the three triangle vertices using mouse left click; Clear the drawing area using mouse left click;
Polyspiral	Use the relative drawing tools (Turtle Graphics) to implement a polyspiral drawing; Change the World Window size/position to realize zooming/roaming effect; and Use the keyboard for user interaction.	‘+’ (plus): Zooming in; ‘-’ (minus): Zooming out; ‘↑’, ‘↓’, ‘←’, or ‘→’ (directional key): Roaming to the corresponding direction. Num Key (3-9): The number of sides of a polyspiral shape (3 sides shown right).
Tweening	Learn the key-frame animation technique of cartoon films – tweening animation;	Specify the vertices of a polygon using mouse left click, and Complete/close the polygon using mouse right click; [f]: Speed up; [s] Slow down the animation; [c] Clear the scree and Resart
Tweening& Snowflake	Draw complicated pictures with simple motifs with turtle graphics and affine transformations.	Demo: Tweening [F1], Flurry [F3], Snowflake [F2] ‘+’/‘-’: Zooming in/out; Directional key: Roaming
Stereo View	Learn to produce stereo views with two separate cameras, and to control & fly the camera.	Use ‘-’/‘+’ key to move the camera along n-axis (i.e. zooming in/out), Use directional keys to move the camera along u- or v-axis (i.e. roaming). For Instruction, Click at 3D Auto Stereogram

Work Title	Goal/Description	Control/Note	Screen Copy
Online Calculator for "Web Design & Programming using C#"	Create/Build 3 web pages (.aspx) using "MasterPage.master"; Create/Apply "Themes" (.css, .skin, .jpg) for different web pages; Program the page (Calculator.aspx.cs) to make a fully functional Calculator using C#	This is a basic calculator only for simple calculations. All calculations are completed at the server. Many postback events and frequently page rendering slow down web browsing. Decimal number input: 0.5, 1.5 (but not .5). Negative number input: "-5" by keying in "5" & "+/-" (rather than "+/-" & "5").
N-Queen Problem for "Data Structure and Algorithms"	Learn to use a Stack (with C++ programming) to solve the "N-Queen" problem; In chess, a queen can move horizontally, vertically, or diagonally. Place 8 queens on an ordinary chess board (8x8) so that no two queens are attacking/capturing each other.	Input the number of Rows(N) For a NxN Chessboard (3 < N < 51); The program gives the Coordinates of the N-Queens as (Row#,Col#), and tells the total number of moves (a huge number when N is large).
TCP Client/Server Socket for "Network Programming using C#"	Learn the TCP Socket programming skills using C#; Write a TCP Client/Server C# program to Verify password; Do math; Text echo; File upload; and Server log. Test the C/S programs on the same machine and/or on two PCs within the same LAN.	System Requirements: 32-bit Windows (XP) & .NET Framework V4.0; Run the TCP-Server program first, and "Unblock" it from any anti-virus software; Input the Server IP address (wired IP preferred) from the Client (or hit Enter); Type a preset password: ASU; Math: Only Integer calculation (done by server); Upload File: File\|C:/Temp/Me.jpg. The uploaded file and the log file ("ZhengServerLog.txt") are found under Directory "C:\" on the server; Exit: type "exit".

Reference Letter	A Reference Letter from my former student (graduated in May 2011) who is now a graduate student with another institute; The student said "Dr. Zheng expected both the projects and the students to succeed in his lab, and eventually he achieved that goal. With his supervision and encouragement, I achieved a lot in his lab which the experience is benefitting me for my present and future career. I appreciate Dr. Zheng for the opportunity of working with him and research team."
Student Evaluation	The Student Evaluation form in Spring 2011 -- The mean score is 4.81 (of 5); The Student commented "Dr. Zheng provided an outstanding opportunity for me to learn what I consider to be complex subject matter. really enjoyed his insight into world affairs and how he tied them to technology and its applications. Overall, an excellent class and instructor."
