|valign="top"|'''Title'''
|CISC440/640 ''Computer Graphics''
|-
|valign="top"|'''Description'''
|A first course in computer graphics covering fundamental concepts and techniques related to rasterization, textures, 2-D and 3-D transformations (including perspective projection), shading, hidden surface elimination, and anti-aliasing, as well as selected topics in modeling, animation, ray tracing, and global illumination.  OpenGL will be used for programming; you should have some familiarity with C/C++ or be ready to learn it.

|valign="top"|'''Grading''' 
|
*60% 	5 programming assignments worth 12% each.  Each homework will be due about 10 days after being assigned (more for the last one)
*20% 	Midterm exam
*20% 	Final exam.  "Bonus topic" lecture material will not be tested
* 2%    Extra credit for completing course evaluation

Graduate students will be given extra tasks to complete or features to implement on each homework, and extra questions to answer on each exam.

Programming assignments will be graded on the basis of correctness, efficiency, and originality.  This is not an introductory programming class, so coding style is not critical.  However, if you want partial credit for something that doesn't quite work, it needs to be well-commented and easy to follow.

For the overall course grade, a preliminary absolute mark will be assigned to each student based on the percentage of the total possible points they earn according to the standard formula: A = 90-100, B = 80-90, C = 70-80, etc., with +'s and -'s given for the upper and lower third of each range, respectively.  Based on the distribution of preliminary grades for all students (i.e., "the curve"), the instructor may increase these grades monotonically to calculate final grades.  This means that your final grade can't be lower than your preliminary grade, and your final grade won't be higher than that of anyone who had a higher preliminary grade.  

I will try to keep you informed about your standing throughout the semester.  If you have any questions about grading or expectations at any time, please feel free to ask me.

|-
|valign="top"|'''Academic policies'''
|Programming projects are due by midnight of the deadline day (with a grace period of a few hours afterward...after sunrise is definitely late).  A late homework is a 0 without a valid prior excuse.  To give you a little flexibility, you have 6 "late days" to use on homeworks to extend the deadline by one day each without penalty.  No more than three late days may be used per assignment.  Late days will automatically be subtracted, but as a courtesy please notify the instructor (and CC the TA) in an e-mail of your intention to use late days before the deadline.  See submission instructions below.

The two exams will be closed book (i.e., no reference materials allowed).  Unless otherwise instructed, you are responsible for all material covered up to the day of the exam, both from the assigned readings (everything in the Readings column of the Schedule below) and in lectures (excluding guest lectures). 

Students can discuss problems with one another in general terms, but '''must work independently on programming assignments unless teams are explicitly allowed for that assignment'''.  This also applies to online and printed resources: you may consult them as references (as long as you cite them), but the words and source code you turn in must be yours alone.    The University's policies on academic dishonesty are set forth in the student code of conduct [http://www1.udel.edu/stuguide/19-20/code.html here].

<!--
Sample program: [http://nameless.cis.udel.edu/class_data/cg/hello/hello.cpp hello.cpp]<br>
All of the Makefile_x examples below should be renamed to "Makefile" before you type "make"

* Ubuntu (recommend 12.04 if you don't already have): [http://nameless.cis.udel.edu/class_data/cg/hello/Makefile_ubuntu Makefile]
** You will need to apt-get install g++ and freeglut3-dev before compiling.  
** [http://www.xemacs.org/ xemacs] is my old-school text editor of choice.  apt-get install xemacs21 to get it, and untar [http://nameless.cis.udel.edu/class_data/cg/xemacs_colors.tar this] in your home directory to get syntax highlighting.
** If you don't have a Linux distribution running currently, it's not that hard to add one to your machine.  The [http://www.ubuntu.com Ubuntu website] has comprehensive instructions on installing it in different ways by creating a separate partition, and another good option is [http://www.virtualbox.org VirtualBox], which lets you run Ubuntu from within Windows.  I found [http://www.psychocats.net/ubuntu/virtualbox these] instructions helpful when setting up my virtual machine.

* Windows PCs with [http://www.cygwin.com/ cygwin] installed (not encouraged): [http://nameless.cis.udel.edu/class_data/cg/hello/Makefile_cygwin Makefile].  When running the setup tool, make sure that the "Devel" category (containing the gcc compiler) and the "Graphics" category (containing the "opengl" package) are chosen to be installed.

* Your own PC (without cygwin):  If you absolutely cannot program anywhere else but in VisualStudio on Windows or Xcode on MacOS or Eclipse or whatever, there are instructions out there for compiling OpenGL programs in these environments.  I'm just not going to be the one to provide them.  If you figure out how to do it, please be sure to post your findings on Piazza, and talk to the TA about what to submit, because he won't necessarily have that IDE.  

* UD machines (hoek, etc.): I don't recommend using these remote machines for graphics because the hardware acceleration you will get with a local machine greatly helps with program performance, and the GLSL material in the second half of the course won't work here.

<!--
** stimpy: [http://nameless.cis.udel.edu/class_data/cg/hello/Makefile_stimpy Makefile]
** composer machines (strauss, mahler): [http://nameless.cis.udel.edu/class_data/cg/hello/Makefile_composer Makefile].  Make sure to set your LD_LIBRARY_PATH in order to find shared libraries when the program runs ("export LD_LIBRARY_PATH=/usr/lib:/usr/local/lib:/usr/sfw/lib" works for me).  Make sure your make is /usr/local/bin/make (type "which make" to verify).
** If you want to log into any of the above machines remotely and open a window, you need to configure X windows to display on your local machine.  From a Unix machine, you should connect using ssh -X remote.machine.name.  From Windows machines, you need an X Windows server that supports the OpenGL GLX extension such as [http://www.cygwin.com/xfree/ cygwin/xfree] (caveat: be advised that interactive programs may run very slowly because of the double lag of running OpenGL in software and transmitting over the network).  If you want to go this route, you'll also need an SSH client to enable [http://www.udel.edu/topics/connect/sw/exceed/docs/UD-Exceed-how-to-use.html#secure SSH tunneling].  To run xfree, substitute the command xwin -multiwindow for running Exceed in passive mode in the tunneling instructions.

|valign="top"|'''Homeworks'''
|Assignment submissions should consist of a directory containing all code (your .cpp files, header files, makefile if applicable, etc.), any output data generated (e.g., images, movies, etc.), and an explanation of your approach, what worked and didn't work, etc. contained in a separate text or HTML file.  Do not submit executables, .o files, or libraries, please!  The directory you submit for each assignment should be packaged by tar'ing and gzip'ing it or just zip'ing it.  The resulting file should be submitted through [http://www1.udel.edu/canvas/ Canvas].

You may develop your OpenGL, C/C++ code in any fashion that is convenient--that is, with any compiler and operating system that you want--but you must avoid OS- and hardware-specific functions.  Programs which use Python and other languages will not be accepted, nor any programs that rely heavily on OpenGL 2.x functions. <!--If you are unfamiliar with the make command and makefiles, there is some background information here and here.-->
