2008 Consortium for Computing Sciences in Colleges - NW Graphics - Orr SIGGRAPH Graphics Resources SIGGRAPH Conference - Education Component of SIGGRAPH – Education Committee – Education Resources (next slide) – Education Program: presentations at the conference of particular interest to educators New pricing structure so one can attend for one day.

2008 Consortium for Computing Sciences in Colleges - NW Graphics - Orr SIGGRAPH Education Committee Community Building Resources: CGEMS, cgSource, Education Index, Listserv Projects: Knowledge Base, Game & Interactive Media Framework, Visualization, Undergraduate Research Alliance, etc Student Competitions: Space-Time, FJORG etc

2008 Consortium for Computing Sciences in Colleges - NW Graphics - Orr Ray Tracing as Part of a CG Course Current Course: – 3 weeks ray tracing – Remaining weeks OpenGL using JOGL Ray tracing – implement the main loop, lighting, shapes & intersections, shadows. – Discuss reflections, refractions, textures, z-buffers

2008 Consortium for Computing Sciences in Colleges - NW Graphics - Orr What does Ray Tracing Bring Takes the mystery out of 3D graphics Learn about – Modeling and abstraction – Basic vector calculations – CG Components: camera, screen, coordinate systems – Phong lighting model

2008 Consortium for Computing Sciences in Colleges - NW Graphics - Orr Downsides/Upsides Downsides – Takes away precious time from learning OpenGL Upsides – Much of what is learned is directly applicable to OpenGL – Difficult to get the same level of understanding when just using OpenGL esp with lighting

2008 Consortium for Computing Sciences in Colleges - NW Graphics - Orr OpenGL 3.0 and Programmable Shaders In OpenGL 3.0, programmers must write their own shaders. Like ray tracing, shaders require the programmer to have a deeper understanding of how vertices and fragments are processed and how lighting is implemented.
