SIGGRAPH Announces Papers and Courses Highlights

siggraph-logo-150

The annual SIGGRAPH Computer Animation confab has released more info about its upcoming program in Los Angeles (August 5-9).

“This year’s program features papers that propel the field forward as rapidly and vibrantly as possible, while at the same time keeping us well-grounded academically, ensuring that SIGGRAPH remains a breeding ground for significant new areas of research,” said Hanspeter Pfister, SIGGRAPH 2012 Technical Papers Chair from Harvard University.

Among the papers featured this year are:

Tensor Displays: Multilinear Optimization of Multilayer Light Field Displays with Directional Backlighting

Authors: Gordon Wetzstein, Douglas Lanman, Matthew Hirsch, and Ramesh Raskar, MIT Media Lab
This paper presents a new display technology for glasses-free stereo viewing. Combining multiple layers of LCD, directional back-lighting, temporal modulation, and a new mathematical formulation, allows for greater depths of field, wider fields of view, and a thinner display.

Printing Spatially Varying Reflectance for Reproducing HDR Images

Authors: Yue Dong, Microsoft Research Asia; Xin Tong, Microsoft Research Asia; Fabio Pellacini, Dartmouth College and Sapienza University of Rome; and Baining Guo, Microsoft Research Asia
When traditional photographs are printed, the range of brightness can be heavily compressed, and the result can look flat. This paper presents a solution for viewing high-dynamic-range (HDR) images using a reflective sheet of paper, glossy ink, and a torch light illuminating the paper. With the proposed technique, one can get a better sense of the range of brightness in the scene and adjust it by moving the light or the paper.

Structure-Aware Synthesis for Predictive Woven Fabric Appearance

Authors: Shuang Zhao, Kavita Bala, Steve Marschner, and Wenzel Jakob, Cornell University
Using 3D scans of real fabrics to design new 3D fabrics for rendering. The fabrics are rendered in physically based way, which allows textile designers to predict how a given weave pattern would look if it were fabricated, resulting in highly realistic results for textile design, ecommerce, entertainment, and apparel visualization.

Out of 412 submissions, 94 papers were conditionally accepted to SIGGRAPH 2012, representing an acceptance rate of 23 percent. A complete listing of all selected Technical Papers will be available on the web site in late May. Technical Papers are published as a special issue of ACM Transactions on Graphics (TOG). An additional 37 TOG papers published during the past year will also be featured at SIGGRAPH 2012.

Here is a glimpse at the courses (1.5 hours) or half-day (3.25 hours) available to attendees this year:

Physically Based Sound for Computer Animation

Authors: Doug James, Jeffrey Chadwick, and Changxi Zheng, Cornell University
This course addresses the need to make the principles and methods of physically based sound accessible to a broader graphics audience. It covers sound-source models for numerous animated phenomena (rigid bodies, fracture, thin shells, cloth, fluids, and fire), and take a hands-on approach to implementing practical systems.

Computational Displays: Combining Optical Fabrication, Computational Processing, and Perceptual Tricks to Build the Displays of the Future

Authors: Gordon Wetzstein, MIT Media Lab; Douglas Lanman, MIT Media Lab; Diego Gutierrez, Universidad de Zaragoza; and Matthew Hirsch, MIT Media Lab
This course introduces computational displays that exploit the co-design of optical elements and efficient computational processing while taking particular characteristics of the human visual system into account. Applications include 3D displays, next-generation projection systems, high-dynamic-range displays, perceptually driven devices, and computational probes.
