This application shows high resolution aerial data of the areas affected by the fires. The data resolution is extremely high at 0.5 meters for the imagery and 2 meters for elevation. Our demonstration shows this data embedded into an osgEarth-based visualization framework, which allows adding such data to any place on our planet and viewing it in a way similar to Google Earth, but with full support for high-end visualization systems.

ArtifactVis (Kyle Knabb, Jurgen Schulze, Connor DeFanti, 2008-2012)

Khirbit.jpg For the past ten years, a joint University of California, San Diego and Department of Antiquities of Jordan research team led by Professor Tom Levy and Dr. Mohammad Najjar has been investigating the role of mining and metallurgy on social evolution from the Neolithic period (ca. 7500 BC) to medieval Islamic times (ca. 12th century AD). Kyle Knabb has been working with the IVL as a master's student under Professor Thomas Levy from the archaeology department. He created a 3D visualization for the StarCAVE which displays several excavation sites in Jordan, along with artifacts found there, and radio carbon dating sites. The data resides in a PostgreSQL data bank with the PostGIS extension, which the VR application uses to pull down the data at run-time.

GreenLight.png The SUN Mobile Data Center at UCSD has been equipped with a myriad of sensors within the NSF funded Greenlight project. This virtual reality application attempts to convey the sensor information to the user while retaining spatial information inherent in the data by the arrangement of hardware in the data center. The application links on-line to a data base which collects all sensor information as it becomes available and stores a complete history of it. The VR application can show current energy consumption and temperatures of the hardware in the container, but it can also be used to query arbitrary time windows in the past.

ScreenMultiViewer (John Mangan 2011)

Neuroscience and Architecture (Daniel Rohrlick, Michael Bajorek, Mabel Zhang, Lelin Zhang 2007-2011)

Neuroscience.jpg This projects started off as a Calit2 seed funded project to do a pilot study with the Swartz Center for Neuroscience in which a human subject has to find their way to specific locations in the Calit2 building while their brain waves are being scanned by a high resolution EEG. Michael's responsibility was the interface between the StarCAVE and the EEG system, to transfer tracker data and other application parameters to allow for the correlation of EEG data with VR parameters. Daniel created the 3D model of the New Media Arts wing of the building using 3ds Max. Mabel refined the Calit2 building geometry. This project has been receiving funding from HMC.

Android Navigator (Brooklyn Schlamp, Summer 2011)

Image-missing.jpg This project implements an Android phone based navigaton tool for the CalVR environment.

Ground Penetrating Radar (Philip Weber, Albert Lin, 2011)

Image-missing.jpg Calit2's Albert Yu-Min Lin has been named to the 2010 class of National Geographic Emerging Explorers. His current research interest is to find the tomb of Genghis Khan in Mongolia, albeit without physically turning a single rock, but only by analyzing a variety of data modalities such as satellite imagery, aerial photography, and sub-surface radar. This demonstration shows three scanning modalities in one visualization application: magnetic, electro-magnetic, and ground penetrating radar. The latter is able to penetrate the ground the deepest, so we chose to focus on it when it comes to visualizing depth data. Spheres with a depth-based color scheme are used to visualize the data. The user can interactively select how deep they want to go under ground, and then fly around to examine the data and put it in perspective with the other two modalities.

3D Reconstruction of Photographs (Matthew Religioso, 2011)

Wiki.jpg Reconstruct static objects from photographs into 3D models using the Bundler Algorithm and the Texturing Algorithm developed by prior students. This project's goal is to optimize the Texturing to maximize photorealism and efficiency, and run the resulting application in the StarCAVE.

Real-Time Geometry Scanning System (Daniel Tenedorio, 2011)

Dtenedor-wiki-icon.png This interactive system constructs a 3D model of the environment as a user moves an infrared geometry camera around a room. We display the intermediate representation of the scene in real-time on virtual reality displays ranging from a single computer monitor to immersive, stereoscopic projection systems like the StarCAVE.

Real-Time Meshing of Dynamic Point Clouds (Robert Pardridge, James Lue, 2011)

Marchingcubes.png This project involves generating a triangle mesh in over a point cloud that grows dynamically. The goal is to implement a meshing algorithm that is fast enough to keep up with the streaming input from a scanning device. We are using a CUDA implementation of the Marching Cubes algorithm to triangulate in real-time a point cloud obtained from the Kinect depth-camera.

LSystems (Sarah Larsen 2011)

Object-Oriented Interaction with Large High Resolution Displays (Lynn Nguyen 2011)

Lynn selected.jpg Investigate the practicality of using smartphones to interact with large high resolution displays. To accomplish such a task, it is not necessary to find the spatial location of the phone relative to the display, rather we can identify the object a user wants to interact with through image recognition. The interaction with the object itself can be done by using the smart-phone as the medium. The feasibility of this concept is investigated by implementing a prototype.

MatEdit (Khanh Luc, 2011)

Hmi.jpg In this project we visualize the data from various collaborating companies which provide us with data stored on harddisks or data transferred over networks. In the first stage, Andrew created an application which can display the directory structures of 70,000 harddisk drives of Microsoft employees, sampled over the course of five years. The visualization uses an interactive hyperbolic 3D graph to visualize the directory trees and to compare different users' trees, and it uses various novel data display methods like wheel graphs to display file sizes, etc. More information about this project can be found at [1].

Hotspot Mitigation (Jordan Rhee, 2008-2009)

Hotspot.png ECE Undergraduate student Jordan Rhee has been working on algorithms for hotspot mitigation in projected virtual reality environments such as the StarCAVE. His COVISE plugin is based on a GLSL shader which performs the mitigation in real-time, minimizing the performance impact on the application.

Image-missing.jpg UCSD graduate Daniel Tenedorio is working on parallelizing the simulation algorithm of the Atlas in Silico art piece, supported by an NSF funded SGER grant. Daniel's goal is to be able to support the entire CAMERA data set, consisting of 17 million data points (open reading frames). Daniel is going to use the CUDA architecture of NVidia's graphics cards to achieve a considerable performance increase.

Animated Point Clouds (Daniel Tenedorio, Rachel Chu, Sasha Koruga, 2008)

Rachel.jpg UCSD students Daniel Tenedorio and Rachel Chu collaborated as PRIME students between NCHC in Taiwan and Osaka University. They worked on a 3D teleconferencing project, for which they used data from a 3D video scanner at Osaka University and streamed it across the network between NCHC and Osaka. Their VR application now runs in the StarCAVE at UCSD. Sasha Koruga has been continuing this project in the winter quarter 2009.

6DOF Tracking with Wii Remotes (Sage Browning, Philip Weber, 2008)

Image-missing.jpg Past research at Calit2 has developed an affordable means of creating large high-resolution computer displays, the OptiPortals. Contemporary input devices for tiled display walls, which go beyond the capabilities a desktop mouse can offer, are either very expensive, or less than satisfactory. Some controllers can cost $40,000, which defeats the benefits of the relatively inexpensive OptiPortal. Alternately, currently available inexpensive methods leave much to be desired: the same image output on the tiled display wall is also shown on a standard sized control monitor using a standard mouse as input, leaving the user without a means of direct interface with the OptiPortal. In order to create an improved interface for the OptiPortal, research must be done in the area of 3D location tracking that is accurate to within a few millimeters, yet maintains a reasonable cost of production and an intuitive design. The focus of this project is to use multiple Wii Remotes for six degree of freedom tracking. We are going to integrate this new input device scheme into the COVISE software, so that existing software applications can directly benefit from this research.

Spatialized Sound (Toshiro Yamada, Suketu Kamdar, 2008)

Image-missing.jpg Peter Otto's group created a 3D sound system which we can control from the StarCAVE by positioning a sound source in a 3D environment. In our demonstration, the sound source is represented as a cone and can be placed in the pre-function area on the 1st floor of the virtual Calit2 building.

Video in Virtual Environments (Han Kim, 2008-2010)

Mipmap-video.jpg Computer Science graduate student Han Kim has developed an efficient "mip-map" algorithm that "shrinks" high-resolution video content so that it can be played interactively in VEs. He has also created several optimization solutions for sustaining a stable video playback frame rate when the video is projected onto non-rectangular VE screens.


LOOING/ORION (Philip Weber, 2007-2009)

Orion.jpg Under the direction of Matt Arrott, Philip created an interactive 3D exploration tool for simulated ocean currents in Monterey Bay.

Interaction with Multi-Spectral Images (Philip Weber, Praveen Subramani, Andrew Prudhomme, 2006-2009)

Adoration.jpg In this project, a versatile high resolution image viewer was created which allows loading multi-gigabyte size image files to display in the StarCAVE and on tiled display walls. Images can consist of multiple layers, like Maurizio Seracini's multi-spectral painting scans. The "Walking into a DaVinci Masterpiece" demonstration in the auditiorium uses this COVISE module. Other images we can display with this technique are the Golden Gate Bridge, an USGS map of La Jolla, NCMIR's mouse cerebellum, the Brain Observatory's monkey brain, and cancer cells from Andy Kummel's lab.

Finite Elements Simulation (Fabian Gerold, 2008-2009)

Fem-vis.jpg In this project, Fabian created a simulation module with attached visualization capability. The simulation calculates the stress on a 3D structure which the user can design directly in the StarCAVE. Then the user can run a pre-recorded earthquake on the structure to see where and how strong the forces are on the various elements of the structure.

Palazzo Vecchio (Philip Weber, 2008)

Vecchio.jpg Philip Weber created the PointModel viewer, which renders LIDAR point data sets like Palazzo Vecchio in the StarCAVE. Philip implemented a hierarchical rendering algorithm which allows rendering two million points in real-time. This application also supports other point data sets like UCSD's shake table at the Englekirk site.

Virtual Architectural Walkthroughs (Edward Kezeli, 2008)

Selected scans exist at super high resolution of hundreds of millions of pixels and can be magnified across the whole wall.

Research Intelligence Portal (Alex Zavodny, Andrew Prudhomme, 2007-2008)

Image-missing.jpg Alex and Andrew created the Research Intelligence kiosk application under a Calit2 grant. They use a visualization technique which is based on smooth transitions between different states of the displayed 2D and 3D geometry. This demonstration runs on a 2x2 tiled display wall on the 5th floor.

New San Francisco Bay Bridge (Andre Barbosa, 2007-2008)

Baybridge.jpg Structural engineering graduate student Andre Barbosa developed a virtual reality application for the StarCAVE. The software allows the user to view and fly through a 3D model of a large part of the new San Francisco bay bridge. His application uses a layered approach to reduce the number of concurrently displayed polygons in order to achieve real-time frame rates. The original data set was created by CalTrans with Bentley's Microstation CAD software. One of Andre's accomplishments was to convert the original, highly detailed CAD data set to a 3D model that could be rendered at interactive frame rates in the StarCAVE.

Birch Aquarium (Daniel Rohrlick, 2007-2008)

HD Camera Array (Alex Zavodny, Andrew Prudhomme, 2007)

Hd-camera-array.jpg In this Rincon funded project, we are able to stream video from the two Ethernet HD cameras and display the warped videos simultaneously on the receiving end. The user can then interactively change the bitrate of the stream, change the focal depth of the virtual camera, and manually align the images. The tiled display wall is accessed through a SAGE module.

Atlas in Silico for Varrier (Ruth West, Iman Mostafavi, Todd Margolis, 2007)

Atlas-in-silico.jpg As genomics digitizes life, the organism and self are initially lost to data, but ultimately a broader meaning is re-attained. ATLAS in silico blends art, science, dynamic media and emerging technologies to reflect upon humanity's long-standing quest for an understanding of the nature, origins, and unity of life. This multimedia art installation was displayed at SIGGRAPH 2007.
