OpenGL ES is the 3D graphics API used on the iPhone, Android and Symbian platforms, Playstation 3, &c. for B481 coursework, we'll use OpenGL ES desktop-based simulators students with OpenGL ES capable hardware (such as iPod touch, iPhone, Nokia N95, T-Mobile G1, &c.) will be encouraged to test B481 programming assignments on their own devices rapid graphics prototyping in Second Life: dynamic scene graphs virtual reality programming techniques for Massively Multiuser Virtual Worlds Linden Scripting Language                        Course Description Course Prerequisites Course Objectives Course Policies Course Topics                       Readings  Labs  Exams and Grades  Weekly Schedule  Selected Topics               Information on this page is preliminary and subject to change: consider it a beta version.

	Course Description Computer Graphics (CG) techniques. Introduction to graphics hardware and software. Two-dimensional graphics methods, transformations, and interactive methods. Three-dimensional graphics, transformations, viewing geometry, object modeling, and interactive manipulation methods. Basic lighting and shading. Video and animation methods.   Course Prerequisites   P: CSCI C343 or H343, MATH M301 or M303, or consent of instructor. Familiarity with Unix and C programming experience are highly recommended; you will need to learn C quickly if you do not know it already. We will review the mathematics briefly.   Course Objectives   B481 is the main course in computer graphics for Computer Science undergraduate students.   Interactive graphics is a crucial part of many interfaces and applications. A basic knowledge of computer graphics (CG) is useful for any task that involves a computer. This course concentrates on: fundamental principles of displaying 2D information using computer graphics 3D programming for geometry modeling, transformation, viewing, lighting and shading interactive techniques for real-time computer graphics dynamic scene-graphs APIs and engines for virtual reality (VR) For the Spring 2009 semester, we also plan to explore OpenGL ES programming for  mobile  devices By the end of this semester, students should be able to: understand the fundamental stages and mathematical foundation of the 3D polygon projection rendering pipeline develop interactive 2D and 3D graphics applications using OpenGL and OpenGL ES describe the relative advantages and disadvantages of low-, middle-, and high-level computer graphics identify state-of-the-art trends in graphics hardware, display devices, and rendering methods Additional considerations   This is not officially a programming in the large course. However, there will be several coding assignments. You will be writing C code to program OpenGL and OpenGL ES APIs on linux systems in the Burrow, and LSL code for VR programming within Second Life. Any Unix-based systems available in STC labs are also likely adequate for development. Other programming languages, APIs or OSes will not be considered for assignments submitted for grading.   Course Policies   All students are required to know and follow Computer Science Department policies on Academic Integrity, dishonesty, and cheating.   Selected Topics   3D Graphics polygon-projection model-based 3D graphics standard OpenGL API programming OpenGL ES and 3D graphics programming for mobile devices (new!) Vertex Arrays, Buffer Objects touch-based input, accelerometer events, proximity sensors   Readings   Textbooks Required: Shreiner, Woo, Neider, Davis: OpenGL Programming Guide: The Official Guide to Learning OpenGL, Version 2.1, 6th Edition, Jul 2007 Addison Wesley Professional Recommended: Peter Shirley: Fundamentals of Computer Graphics, Second Edition, July 2005 A K Peters (available online from Books24x7, on campus and off-campus with authorized IU logon) Munshi, Ginsburg, Shreiner: OpenGL ES 2.0 Programming Guide, Jul 2008 Pearson Education (this book covers only OpenGL ES 2.0, and B481/Spring2009 will more likely focus on OpenGL ES 1.x as available on most currently available devices) possible choice, currently still reviewed: Pulli, Aarnio, Miettinen, Roimela, Vaarala: Mobile 3D Graphics with OpenGL ES and M3G, Morgan Kaufmann, 2008 Elsevier   Labs   Labs will meet Fridays 1:00PM-2:00PM   Exams and Grades Final Exam: 30% Midterm: 20% Coding assignments and projects: 30% Readings, written assignments, in-class presentations: 15% Participation (active class presence and journal note-taking): 5%   Weekly Schedule   Lecture TR, 1:00PM-2:15PM Lindley Hall 115 Lab F, 1:00PM-2:00PM Lindley Hall 030   Course Topics   Note: the following outline is a -quite ambitious- superset of what we'll actually have time to cover during the semester. It will be refined as the Spring 2009 semester start approaches. Study guides for mid-term and final exams will specify which material will be tested, such as amount of details and emphasis on specific topics.
