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.

Based
upon the popularity of the program at SIGGRAPH 2008, this year's
Technical Papers program is once again expanding to include 19
conference presentations for each paper published this year in the
journal ACM Transactions on Graphics (TOG).
