The following three articles highlight how Silicon Graphics systems are being used in Iowa State's Mechanical Engineering Department
A Virtual Environment for Manufacturing Systems
Principal Investigator: Dr. James H. Oliver, Associate Professor, Iowa State University Mechanical Engineering Department, Director of the ISU Visualization Laboratory
The
Virtual Environment for Manufacturing Systems project is focused on
building a theoretical framework to support the development of a
virtual environment model of a computer-integrated manufacturing
workcell to facilitate off-line programming, system simulation, and
visual and analytical verification of system capabilities and
performance. Using computer visualization, geometric modeling, and
virtual interface technologies, this project focuses on developing a
functionally accurate virtual substitute for an actual manufacturing
workcell. Research emphasizing the development and utilization of
virtual environments is divided into three complementary areas of
focus: off-line programming; material removal process simulation; and
assembly sequence planning. The combined capabilities will form a
first-generation virtual manufacturing workcell. The complete system
will allow immersive user interaction with crucial parameters affecting
system performance and provide rapid visual feedback. All of this development
is being performed on Silicon Graphics' machines.

Robotic and Magnetic Interface for Virtual Reality Force Interactions
Principal Investigator: Dr. Greg R. Luecke, Professor, Iowa State University Mechanical Engineering Department
The objective of Robotic and Magnetic Interface for Virtual Reality
Force Interactions research is the development of a haptic interface
system that allows force interactions with computer-generated virtual
reality graphical displays. The system is based on the application of
electromagnetic principles to couple the human hand with a robotic
manipulator. Using this approach, the forces are transmitted between
the robot exoskeleton and the human without using mechanical
attachments to the robot. This research includes the development and
interfacing of the mechanical hardware, development of a virtual
environment for studying realtime interactions, and the generation of
computer models for computation of interaction forces between the
virtual objects and the human. The new system will provide the human
user with a unique interface to the computer-generated virtual world
that will apply computer generated forces to the digits of the human
operator's hand according to an arbitrary model residing within the
computer program. Currently, Silicon Graphics' systems are being used
to compute and display motion of objects in the graphical environment.
This project is sponsored by the National Science Foundation.
For more information, call 515-294-5916.
Visualization of Structural Response Using Design Sensitivity Analysis
Principal Investigator: Dr. Judy M. Vance, Assistant Professor, Iowa State University, Mechanical Engineering Department
The development of a prototype visualization tool for multifunction
optimization and variability analysis is the research focus of the
Visualization
of Structural Response Project that is being conducted
for the Ford Motor Company. The software under construction reads
baseline results computed by CAE tools (e.g. MSC/NASTRAN), associated
design sensitivity analysis (DSA) data, and design variable
variability, and uses the data to predict, continuously and
interactively, a new system response given changes in design
variables. The user interactively inputs design changes by using the
mouse to move virtual dials displayed on the screen or by manually
turning physical dials on a dialbox connected to the computer. This
tool will allow Ford engineers to identify a set of realistic and
robust design targets for optimization.
This software tool also displays the variability response of the system from design variable changes. The multi-windowing capabilities of today's workstations allow simultaneous display of results from a multiple of analysis data. The software is being developed on Silicon Graphics' equipment using OpenGL and X/Motif. When completed, Ford Engineers will be able to look at many different types of analysis data, including noise, vibration, and handling (NVH); safety; durability; and ride/handling; and view both the effects that changing design variables have on these responses and the predicted statistical distribution of those responses.
For more information, call 515-294-9474.
Wave Loch, Inc., located
in La Jolla, California, has developed a new
class of water attraction called the "Flow Rider." The Flow Rider,
emulating a perfect 6-foot wave, uses body boards as vehicles on an
inclined sheet of flowing water.
The Flow Rider concept is the brainchild of California attorney-turned-inventor Tom Lochtefeld. Lochtefeld worked with surfing legend Carl Ekstrom, and scientists at Scripps Oceanographic Institute at the University of California at San Diego, to mathematically define the ideal surfing wave and create the technology to reproduce it. Bruce McFarland, responsible for the full-scale design, used Silicon Graphics' Indy R4000 and 3D solids CAD/CAE software to design the compound contoured surfaces of the Flow Rider, the foundation, and the hydraulics. Finite element models for structural analysis were run on the Indy, as well.
The introduction of Flow Rider opened up the sport of bodyboarding and
landlocked would-be-surfers are experiencing the "perfect
wave" on a regular basis. Flow Rider is currently featured in
waterparks in Texas, central Florida, and Vista, California.
Internationally, Flow Rider can be found in Las Olas, Mexico,
Nishiwaki, Japan and high in the mountains of Telemark, Norway (pictured at left).

Ultrasound Visualization Research: Computer-Augmented Vision Technology
Principal Investigator: Henry Fuchs, Federico Gil Professor of Computer Science and Adjunct Professor of Radiation Oncology, Department of Computer Science, University of North Carolina
At the University of North Carolina, a team of researchers is exploring the application of augmented reality to develop and operate a system that allows a physician to see directly inside a patient. Augmented reality combines computer graphics and virtual reality displays with images of the real world. The Ultrasound Project team recently designed and built a prototype realtime computer-augmented vision system based on a Silicon Graphics Onyx RealityEngine2 (RE2) high-performance graphics workstation equipped with a Sirius Video realtime frame grabber unit. This system makes heavy use of the high-speed, image-based texturing capability available in the RE2.
First experiments with this new system have yielded encouraging results and the team is working on the development of many algorithms to improve the system's performance. For example, it is expected that the display software can be enhanced to present an image that is almost free of spatial misregistration and perceived lag.
The application of this technology is far-reaching as typified by the Ultrasound-guided Breast Biopsy Project. Ultrasound-guided biopsy of breast lesions is used for diagnostic purposes, partially replacing open surgical intervention. It is a difficult procedure to learn and perform, requiring good hand-eye coordination and three-dimensional visualization skills to guide the biopsy needle to the target tissue area with the aid of ultrasound imagery.
The use of computer-augmented vision technology can significantly simplify the procedure and the team at UNC is targeting their current and near-term future research efforts toward building a system that will aid a physician in performing an ultrasound-guided needle biopsy. Results from preliminary experiments with phantoms and with a human subject (using the Silicon Graphics-based realtime system) have been encouraging.

Magnetic Resonance Microscopy of Embryos
Principal Investigators: Bradley R. Smith, Elwood Linney, Dale S. Huff,
G. Allan Johnson
Center for In Vivo Microscopy (a National Research Resource
Center), Duke University Medical Center
Researchers at Duke University Medical
Center are currently involved in
a study of Magnetic Resonance Microscopy of Embryos. Magnetic resonance
(MR) microscopy is a non-destructive technique capable of generating
three-dimensional images of developing structures from whole embryos.
It facilitates the evaluation of complex structures by allowing them to
be studied in any plane of sectioning for cut-away views and from any
angle for whole specimen views. Using Silcon Graphics' workstations
with Vital Images' VoxelView_ULTRA 2.0 software, researchers are able
to assess the shape, position, and timing of anatomical structures
during development. Such detailed and specific information is
indispensible to identifying and understanding the mechanisms of normal
and abnormal morphogenesis.
This technique has been used in live embryo imaging and holds great
promise for studying development in individual embryos over time. To
that end, the research team developed a mouse embryo culture chamber
compatible with the MR microscope to follow development over 12 to
48-hour time periods. MR microscopy generated clear definition of
complex three-dimensional embryonic structures in a non-destructive
manner. The 3D images are free of of the sectioning and registration
artifacts often associated with reconstructions based on traditional
microscopy. In the image shown here, individual aortic arches or valves
can be identified and and isloated for viewing in multiple planes and
from varying angles.
For more information, contact Brad Smith at 919-684-7852.
Researchers at the Medical College of Georgia and the Interactive Media
Technology Center at Georgia Tech have created a device incorporating
virtual reality to simulate the look and feel of eye surgery. The
simulator provides an environment for recursive and time-critical
training for medical students and practicing surgeons. Using Silicon
Graphics' Onyx computer, surgeons and students can practice coping with
surgical emergencies much the same way pilots use flight simulators to practice
coping with in-flight emergencies.
The Eye Surgery
Simulator displays photo-realistic images of the
anterior segment of the eye derived from photographs of bank eyes and
has linear tactile feedback for realtime "feel" of tool-tissue
interaction. The haptic information was based on a model derived from
data gathered by monitoring surgical tool forces during procedures
performed on a bank eye at the Medical College of Georgia.
After procedures are recorded, the information is quantified and replayed for evaluation by the student and instructor. The simulator makes it possible to practice new techniques, rehearse complicated surgeries, and present surgical complications and rare maladies as part of routine training.
For more information, contact John Cordova at-404-894-4195, or email jcordova@maryann.oip.gatech.edu
Commercial Software Package For Surgical Training
High Techsplanations, Inc.
(HT), founded in 1987, develops virtual
environments for simulation-based surgical training. Current research
and development efforts have resulted in an advanced demonstration of
virtual reality in medical education.
The
Teleos Medical Education System was developed over the last three
years for use in the development of Silicon Graphics-based surgical
simulations, taking advantage of the hardware based texture
capabilities of the Onyx RealityEngine(tm) for photorealism. The system
consists of two applications:
Typically, the designer program will be used by medical content experts while the trainee will interact with, but not create new, surgery scenarios. The simulation engine allows the trainee to use spatial motion tracking and force feedback devices, along with stereo viewing, to provide an experience that parallels the actions of the actual surgery they are practicing.

Ron Howard's "Apollo 13" for MCA/Universal Pictures is remarkable for its
success at the box office, but perhaps more remarkable is the fact that
no NASA footage was used in the film. All of the visual effects for the
film were supervised by Digital Domain, a digital production studio in
Venice, California, and they relied primarily on
Side Effects' PRISMS as
the primary tool for all computer graphics elements.
Working with about 40 Silicon Graphics Indigo2 workstations linked to
several Silicon Graphics eight-processor Onyx supercomputers, Digital
Domain created everything from the rocket's plume of fire and the gas
venting from the damaged oxygen tanks to the Earth, moon and stars. The
demands of this film were unique with the audience bringing their
expectations into the theater. The artists on the project needed the
audience to believe that they were watching the launching of Apollo 13
and experiencing the vastness of space.
The launch sequence presented one of the biggest challenges for the
creative team. They built scale models of Apollo 13 and the Vehicle Assembly
Building at the Manned Space Center. The model was filmed against a
black background and then composited to appropriate backgrounds. Digital
Domain generated numerous details such as the ice condensing on the rocket,
tumbling and shattering as the engines ignited and the blankets of
vapor streaming down the side of the rocket.

Visualization of Binary Star System R-Aquarii
Investigators: Dr. Jan M. Hollis (NASA/GSFC) - principle investigator Space Data and Computing Division, Richard G. Lyon (Hughes STX) - co-investigator High Performance Computing Branch, Dr. John E. Dorband (NASA/GSFC) High Performance Computing Branch, Walter A. Feibelmen (NASA/GSFC) Science Operations Branch, Pamela O'Neil, Ron Shiri (Hughes STX) Scientific Applications and Visualization Branch
The symbiotic binary star system R-Aquarii has been under observation by the Hubble Space Telescope's Faint Object Camera (FOC). The observations, made prior to the correction of the FOC's optics, suffered from image blur; reconstruction of the images, however, through use of Maximum Entropy Image Deconvolution at Goddard Space Flight Center sufficiently improved the image and scientists were able to measure the motion of the jets and to generate a simplified model of the stellar dynamics.
Reasearchers at the Scientific Visualization Studio, using Silicon
Graphics workstations, generated two animations based on the Hubble
images. One was a movie loop in which the three deblurred images were
pseudo colored and shown in sequence. In this format the motion of the
jets is observed. This motion is not apparent from still images.
Studying this loop helped to identify corresponding regions in the jets
in order to measure the motion. The other animation was a 3-D
perspective view of 198 of the iterations of the Maximum Entropy
Deconvolution deblurring process as it was applied to the 1992 Hubble
image.
The Hubble images were first converted from the FITS format to the format native to the Silicon Graphics workstations. A visualization software package was then used to apply the color maps to the images for the movie loop animation and to create the 3-D perspective views with contour lines for the 3-D animation. The package also allowed changing the view point of the surface as the animation progressed to help show up details of the deblurring process.

Visualization of Lunar Topography from Clementine Data
Investigators: Dr. David E. Smith (NASA/GSFC) - principle investigator Laboratory for Terrestrial Physics, Maria T. Zuber (Johns Hopkins University) - principle investigator Laboratory for Terrestrial Physics, Frank G. Lemoine(University of Maryland) - Co-investigator Space Geodesy Branch, Gregory A. Newmann (Johns Hopkins University) - Co-investigator Department of Earth and Planetary Sciences
The Clementine Mission was a joint DoD/NASA project originally part of "Star Wars", the Strategic Defense Initiative. The spacecraft carried a laser-ranging instrument (LIDAR) as well as cameras and other sensors that could be used to measure the moon's topography. The investigators applied special techniques to analyze the Clementine data and create a digital topographic model. These techniques helped to reveal previously unknown details of the moon's important impact features, including the Orientale and South Pole-Aitken craters, and led to the discovery of several ancient, degraded craters created by early lunar impacts.
To visualize the topographic data set received from the Clementine
science team, members of the Scientific Visualization Studio (SVS)
converted the data into formats that could be read into the SVS
visualization software system. Using a high resolution lunar image,
researchers created a texture map consisting of 16 Megabytes of data.
They created a "flight path" using Wavefront visualization software,
zooming in from a distant viewpoint and circling the southern
hemisphere at about 20 degrees south. The topography was exaggerated by
a factor of 7 to provide an optimum view of the lunar features. The
research team worked nearly three weeks on the Silicon Graphics Onyx to
generate the 1.5 minute animation.
