An Introduction to OpenGL 4.0 Programming
Friday, 17 December | 7:00 午後 - 10:45 午後 | Room E5
OpenGL is the most widely available library for creating interactive computer graphics applications across all of the major computer operating systems. Its uses range from creating applications for scientific visualizations to computer-aided design, interactive gaming and entertainment, and with each new version, its capabilities reveal the most up-to-date features of modern graphics hardware.
This course provides an accelerated introduction to programming OpenGL with an emphasis on the most modern methods for using the library. OpenGL has undergone numerous updates in recent years, which have fundamentally changed how programmers interact with the application programming interface (API) and the skills required for being an effective OpenGL programmer. The most notable of those changes was the introduction of shader-based rendering, which was introduced into the API many years ago, but has recently expanded to subsume almost all functionality in OpenGL. The course summarizes each of the shader stages in OpenGL version 4.0 and methods for specifying data to be used in rendering with OpenGL.
While the annual SIGGRAPH conferences have presented numerous courses on OpenGL over the years, recent revisions to the API, culminating in OpenGL version 4.0, have provided a wealth of new functionality and features that enable creation of ever-richer content. This course builds from demonstrating the use of the most fundamental shader-based OpenGL pipeline to introducing all of the latest shader stages.
Introductory computer graphics application programmers who might be creating a computer game, a visualization program, or other interactive application that renders to an image or computer monitor and want to implement their applications in OpenGL.
Presented in English / 영어로 발표 됨
Attendees should be able to read simple computer programs written in the C language and have a basic knowledge of computer graphics concepts (for example, depth buffering and texture mapping).

Dave Shreiner has been involved in presenting OpenGL-related courses at SIGGRAPH since 1998. He is an author of The OpenGL Programming Guide (7th Edition; Addison Wesley; 2005) and co-author of the OpenGL ES Programming Guide (Addison Wesley; 2004). He has authored and presented courses on OpenGL for almost two decades worldwide, including authoring the original introductory OpenGL course taught at Silicon Graphics Computer Systems (SGI), creators of the OpenGL API.
Edward Angel is a professor in the Departments of Computer Science, Electrical and Computer Engineering, and Media Arts and Director of the Art, Research, Technology, and Science Laboratory (ARTS Lab) at the University of New Mexico. He has over 25 years of experience in research and teaching in computer graphics and image processing. He is the author of the popular textbooks Interactive Computer Graphics: A Top-Down Approach using OpenGL (5th Edition, Addison Wesley, 2009), and The OpenGL Primer (Third Edition, Addison Wesley, 2008). He has taught over 100 professional courses worldwide, including at the annual SIGGRAPH conference.
