Date: Fri, 19 Oct 2001 16:41:13 -0400 (EDT) From: Colin Godfrey Subject: Ramesh Raskar talks at MERL, Cambridge, Wed Oct 24 and Thurs Oct 25 Next week Ramesh Raskar is giving two talks on his shader lamps technique. Both talks are at MERL in Cambridge. The Wed. Oct 24 talk is sponsored by SIGGRAPH/Boston, and should be slanted toward graphics. The Thurs. Oct 25 talk is sponsored by the Boston Virtual Reality Group and should be slanted toward VR. Announcements for both are included below, so you could attend either. ====================================================================== 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. ************************************************************************ Directions to Mitsubishi Electric Research Labs, 201 Broadway: Via T Get off the T at the Kendall Square stop on the Red Line. Exit from the subway and then walk directly into the lobby of the Marriott hotel, which is on a courtyard adjacent to the subway exit. Walk straight through the lobby and out the opposite side of the building. The street you are facing is Broadway. Turn left. Walk through 3 traffic lights. 201 broadway is the first building on your right after the third light. We are on the 8th floor. Driving From the intersection of Storrow Drive and Cambridge Street, take the Longfellow bridge over the Charles river to Cambridge. Drive straight on away from the river. You are on Broadway. Go through one traffic light (the Marriot hotel is now on your left). Continue straight through two more traffic lights (you are now passing over some railroad tracks). (Between the first and second of these traffic lights is a parking garage open to the public. Depending on the time of day there may also be on street parking availabe near MERL.) Continue straight through one more light (Mitsubishi is the first building on your right after this light). It says 201 in large numbers on the corner of the building. MERL is on the eighth floor. ************************************************************************ SIGGRAPH/Boston Contacts WWW: http://www.siggraph.org/chapters/boston SIGGRAPH/Boston maintains a mailing list for e-mail announcements of meetings.

We are used to looking at the output of a computer grapics program on a monitor or on a screen. But, how can we see the result of a rendering directly in our environment? For example, how can we make a white clay vase sitting on a table look like it is made up of gold, with fine details? We have recently introduced a new paradigm and related techniques to make the illumination of non-trivial objects practical. I will 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 the Computer Graphics lab of University of North Carolina at Chapel Hill where he received his PhD. 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. He is a member of the ACM.

The group's purpose is to explore the social implications and technical issues that arise from building such systems. Our mission is to provide a forum for bring together industry experts, academic and commercial researchers, artists, hackers and enthusiasts/potential users. If you have a general interest, a passion for this domain or want to code, paint and build such systems, think BVRG. The BVRG was originally established in 1992 as the Boston Computer Society's Virtual Reality Group. Aside from many speakers over the years, the group has built several fully immersive virtual environments for SIGGRAPH dating back to 1993. =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= To subscribe to the boston-vr-announce e-mail announcement distribution list, send the following line in the body of an e-mail message to majordomo@world.std.com: subscribe boston-vr-announce To unsubscribe yourself from this list send the following: unsubscribe boston-vr-announce
