account if you are taking some other course 09 07 04 2002 2004 University of Wisconsin Textbooks and Readings Peter Shirley Fundamentals of Computer Graphics A K Peters 2002 Woo et al OpenGL Programming Guide Third or Fourth Edition Adison Wesley 1999 or 2003 The definitive guide to OpenGL and a reasonable description of general real time 3D graphics It doesn t really matter which edition the differences are not pertinent to this class Class readings Online via the library s reserve system see class web page A collection of papers textbook chapters and other documents Some essential material not contained in the textbook 09 07 04 2002 2004 University of Wisconsin Projects There will be three projects for the course spread evenly through the semester Project 1 Image editing Project 2 Running a maze Project 3 Building a virtual theme park You must submit all three in order to pass the course This rule has never been waived 09 07 04 2002 2004 University of Wisconsin Homeworks There will be a homework every two weeks or so They are intended primarily to explore topics further and to prepare you for the exams They will be graded but only the best five will count Some essential techniques will be presented only in homework For example an review of linear algebra 09 07 04 2002 2004 University of Wisconsin Grading approximate 45 Midterm and Final 45 Projects 10 Homework Everyone must write up their own homework For projects 1 and 3 you have the option of working in pairs 09 07 04 2002 2004 University of Wisconsin Lab Facilities Room B240 contains machines for use in this class They have adequate hardware circa 2001 and the software to make it work Students in CS 559 have priority in the lab There are benefits to working in a lab with your classmates For instance the blackboards frequently display useful hints that someone else scrawled But they also sometimes have incorrect information 09 07 04 2002 2004 University of Wisconsin Software Infrastructure FLTK will be the user interface toolkit Provides windows buttons menus etc C class library completely portable We are currently at version 1 1 0rc6 available for free www fltk org OpenGL will be the 3D rendering toolkit Provides an API for drawing objects specified in 3D Included as part of Windows and in most Unix distributions Although getting hardware acceleration may take some doing Visual Studio NET Visual C 7 1 will be the programming environment for grading To be graded your projects must compile under Visual C on the machines in room B240 09 07 04 2002 2004 University of Wisconsin C This is probably the first and only class in which you must complete large software projects in C without step by step instructions There is a great deal of freedom in the projects which requires that you do your own software design If you are not comfortable in C you will have to take action There are tutorials intended to teach you C assuming you know Java http www cs wisc edu hasti cs368 CppTutorial index html These are intended for the course CS 368 but just do the tutorials The transition to C was one of the biggest issues for past CS559 students Visual Studio also causes issues we will provide a transition tutorial 09 07 04 2002 2004 University of Wisconsin Adding the Class Everyone should be able to add at this point If not email cs559 1 cs wisc edu with

image is intended to describe the light that arrives at your eyes when you view it You can be even more abstract image describes what you should think when you see it Different display devices convey the image content in different ways e g Print and computer monitors use two fundamentally different approaches The same image may look different on different monitors Who cares 09 07 04 2002 2004 University of Wisconsin Image Formats We are familiar with many forms of image Photographs Paintings Sketches Television NTSC PAL SECAM Digital formats JPEG PNG GIF etc etc etc etc Each form has its
