SIGGRAPH 2009 Technical Papers: Technology and Advanced Techniques

Chicago, Ill. - The SIGGRAPH 2009 Technical Papers program will feature the latest computer graphic innovations, ranging from a detailed simulation of intrusive surgical procedures to the development of infra-red flash photography. A total of 439 submissions were reviewed by a panel of 54 jurors, and 78 papers were selected for presentation at SIGGRAPH 2009.
Papers cover core topics of computer graphics, such as modeling, animation, rendering, imaging, and human-computer interaction, and also explore related fields of audio, robotics, visualization, and perception. Presenters hail from all around the globe.

Select highlights from the SIGGRAPH 2009 Papers Program include:

Interactive Simulation of Surgical Needle Insertion and Steering
This paper presents algorithms for simulating and visualizing the insertion and steering of needles through deformable tissues for surgical training and planning. Novel features include a fast mesh maintenance algorithm and physics-based methods for needle-tissue coupling.

Bokode: Imperceptible Visual Tags for Camera-Based Interaction From a Distance
Detailed analysis of how to enable a commodity camera to photograph and capture a 3mm barcode from two meters away. The key is to exploit camera bokeh, which maps binary data encoded in directionally varying rays into a large disk. The next step is to decode ID as well as camera pose for augmented reality applications.

Dark Flash Photography
Camera flashes produce intrusive bursts of light that disturb or dazzle. In this paper, a "dark" camera flash is presented that uses infra-red and ultra-violet light just outside the visible range to capture pictures in low-light conditions while being two orders of magnitude dimmer than a conventional flash.

Real-Time Hand-Tracking with a Color Glove
This research describes a system that can reconstruct the pose of the hand from a single image wearing a multi-colored glove and demonstrates a system as a user-input device for desktop virtual reality applications.

Harmonic Fluids
This presentation proposes an algorithm for synthesizing familiar bubble-based fluid sounds such as splashing, pouring, and babbling. The researchers acoustically augment existing incompressible fluid solvers with particle-based models for acoustic bubble creation, vibration, advection, and radiation. Acoustic transfer functions are estimated using the fast dual-domain boundary integral Helmholtz solver.

Directable, High-Resolution Simulation of Fire on the GPU
This presentation proposes a hybrid particle and grid simulation system which utilizes graphics hardware (GPU) to quickly simulate artist-directable, high-resolution fire. Simulation resolutions as high as 2048 are able to be computed in a few hours by parallelizing work among multiple GPUs.
