Environmental Visualization

The Santa Cruz Laboratory for Visualization and Graphics is a research facility associated with the Baskin Center for Computer Engineering and Information Sciences at the University of California at Santa Cruz. The lab is loaded with 23 Silicon Graphics computers ranging from Indys to Indigo 2 Extremes to an Onyx Reality Engine and a Challenge L.

One recent research focus is geared towards visualizing environmental (meteorologic and oceanographic) data sets. This work is part of the visualization component of REINAS. REINAS is an acronym for Real-time Environmental Information Network and Analysis System. The REINAS system is built to support realtime data acquisition, management, and visualization of environmental data at a regional scale. It is organized into three components: instrumentation/system to support acquisition, spatial and temporal database management, and interactive visualization. The three main classes of users identified are instrumentation engineers and casual users, operational forecasters, and scientists.

To meet the needs of these users, REINAS is organized into three modes of operation: monitor mode (for watching the latest environmental parameters and for obtaining readings from specific instruments), forecast mode (for obtaining standard and customized weather products), and analysis mode (for retrospective analysis of synoptic data).

The Santa Cruz Laboratory publicizes their research efforts by providing internet access to the latest reading from some of their instruments through Xmet. For example, at http://sapphire.cse.ucsc.edu:80/SlugVideo/ you can view the beach conditions from the Dream Inn, Santa Cruz and the current weather conditions a few miles away at UCSC Long Marine Laboratory. The picture at the right is a live shot captured from the Dream Inn camera at 12:21 pm on Tuesday the 6th of November. Images are updated periodically, typically at five minute intervals, when exclusive use of the camera equipment is not required for research.

Product Information

Naval Postgraduate School Releases Latest Version Of NPSNET

The NPSNET Research Group at the Naval Postgraduate School announced the release of NPSNET-IV_8.1, a software system for simulating articulated humans and ground and air vehicles in the Distributed Interactive Simulation (DIS) networked virtual environment. The NPSNET Research Group is currently involved in several virtual environments (VE) projects including the large-scale networking of VE (environments greater than 1,000 players), VE network applications protocols, rapidly reconfigurable VE network protocols, Distributed Interactive Simulation (DIS) protocols, the real-time walkthrough of large-scale networked VEs, world modeling software for managing large scale networked VEs, the instrumentation of the human body and its representation in the networked VE, hypermedia integration - how to place video, audio, imagery and textual data in the networked VE, and geometric modeling - terrain, building and other object modeling.

The NPSNET software, is a result of the group's research efforts in these areas and the integration of proven components of that work into the core software. NPSNET currently is capable of simulating articulated humans, and ground and air vehicles in the DIS networked virtual environment. NPSNET can support about 250-300 players using currently available networking and workstation technology. NPSNET is the first 3D virtual environment that is capable of playing across the multicast backbone (MBONE) of the Internet.

NPSNET runs on Silicon Graphics' workstations. It utilizes proprietary Silicon Graphics' hardware and software features, as well as some auxiliary software packages, and is thus not portable to other systems. To satisfy typical performance requirements, at minimum, an Indigo2 Extreme with 64 megabytes of RAM is recommended. The ideal configuration would be a four-processor Onyx with 128 megabytes of RAM. For specific hardware and software requirements, consult the NPSNET Configuration and Set-up Guide.

White Paper

i3D:A High-Speed 3D Web Browser
Jean-Francis Balaguer and Enrico Gobbetti
Center for Advanced Studies, Research and Development in Sardinia

This paper presents i3D, a system that combines the 3D input and high-performance rendering capabilities of high-end virtual reality systems with the data fetching abilities of network browsers. Using a Spaceball, the user can intuitively navigate inside the three-dimensional data, while selecting 3D objects with the mouse triggers requests for access to remote media documents that can be text, still images, animations or even other 3D models. Time-critical rendering techniques allow the system to display complex 3D scenes at high and constant frame rates, making it possible to use it in the context of large scale projects. The system is currently being used at CERN as a visualization and data management tool for the design of the new Large Hadron Collider, and at CRS4 for the Virtual Sardinia project. i3D is available through anonymous ftp from various sites on the Internet.
