From: "Colin Godfrey" Subject: SIGGRAPH/Boston at MERL, Wed Oct 24 Date: Friday, October 12, 2001 10:23 PM SIGGRAPH/Boston Meeting Announcement Shader Lamps: Animating Real Objects with Projectors Ramesh Raskar Place: Mitsubishi Electric Research Laboratory 201 Broadway, Cambridge MA 02139 8th Floor Time: Wednesday October 24th 2001 Networking time will start around 6:15pm. The feature presentations should start around 7:00 - 7:15pm We are used to looking at the output of a computer graphics program on a monitor or on a screen. But, how can we see the "special effects" directly in our environment? For example, how can we make a clay vase sitting on a table look like it is made of gold, with fine details? The appearance of an object is a function of illumination, surface reflectance and viewer location. Hence, we can rearrange the factors along the optical path and reproduce the equivalent desired appearance. We have recently introduced a new paradigm and related techniques to graphically animate physical objects with projectors. Because the approach is to effectively "lift" the visual properties of the object into the projector, we call the projectors shader lamps. We address the central issue of complete illumination of non-trivial physical objects using multiple projectors and present a set of new techniques that make the process of illumination practical. We show some results and describe the new challenges in graphics, geometry, vision and user interfaces. Ramesh Raskar joined MERL Cambridge Research as a Research Scientist in 2000. Prior to that, he was at the Office of the Future group at UNC's Computer Graphics lab. As part of his dissertation, he developed a framework for projector based 3D graphics by treating a projector as the dual of a camera. Current work includes topics from non-photorealistic rendering, computer vision and intelligent user interfaces ********************************************* SIGGRAPH 2002 Call for Participation ********************************************* The SIGGRAPH 2002, the 29th International Conference on Computer Graphics and Interactive Techniques, is seeking both veteran and novice contributors who work, play, and live with the latest advancements in computer graphics and interactive techniques. The technical presentation submission options include Papers, Panels, Courses, Sketches and Applications, Educators Program, new Web Graphics Program, and Creative Applications Lab. The conference is also seeking contributors for the Art Gallery, Computer Animation Festival, Emerging Technologies, sigKIDS, and Studio, whose work enables attendees to experience the technology. In addition, it is asking for volunteers and support for the following services: GraphicsNet, International Resources, Pathfinders, and Student Volunteers. See the Call for Participation at www.siggraph.org/s2002/cfp/index.html for detailed information on how to submit and the submission deadline for each program. SIGGRAPH 2002, www.siggraph.org/s2002, will be held 21 - 26 July, at the Henry B. Gonzalez Convention Center in San Antonio, Texas. ************************************************************************ SIGGRAPH/Boston Contacts WWW: http://www.siggraph.org/chapters/boston SIGGRAPH/Boston maintains a mailing list for e-mail announcements of meetings.
