Course Description:

Real-time procedural shading was once seen as a distant dream. When the first version of this course was offered three short years ago, real-time shading was possible, but only by combining the effects of tens to hundreds of rendering passes. Today, almost every new computer comes with graphics hardware capable of interactively executing shading functions consisting of thousands or tens of thousands of instructions. This course has been redesigned to address today's real-time shading capabilities and to provide more practical information for practitioners. The course begins with a guide to understand the similarities and differences between real-time and non-real-time shading. It describes methods for accomplishing many common shading tasks in ways that work well on graphics hardware. We present the latest shading hardware developments from several leading hardware vendors. Finally, we provide a brief look under the hood to see what is necessary in hardware and software to make it all happen. The course concludes with a panel-style question and answer session, where participants can ask questions of any presenter or suggest topics of discussion.
