Using OpenGL Vizserver, you can run graphics applications on another system and OpenGL Vizserver serves the resulting graphics to your client machine. You can also use OpenGL Vizserver in conjunction with other products like QuickTransit for Silicon Graphics. QuickTransit allows you to transparently run applications compiled for IRIX MIPS platforms. Hence, QuickTransit greatly augments the number of applications you can run on Silicon Graphics Prism servers. System Requirements OpenGL Vizserver consists of client and server modules. The OpenGL Vizserver server module requires one of the following system types: • SGI Onyx 3000 series with InfiniteReality3 or InfiniteReality4 graphics • SGI Onyx 3000 series with InfinitePerformance graphics • SGI Onyx 300 systems with InfinitePerformance graphics • SGI Onyx 300 systems with InfiniteReality3 or InfiniteReality4 graphics • SGI Onyx 350 systems with InfinitePerformance graphics • SGI Onyx 350 systems with InfiniteReality3 or InfiniteReality4 graphics • Silicon Graphics Onyx2 systems with InfiniteReality2, InfiniteReality3, or InfiniteReality4 graphics • Silicon Graphics Octane or Octane2 systems • Silicon Graphics Onyx4 UltimateVision systems • Silicon Graphics Fuel systems • Silicon Graphics Tezro systems 007-4481-011 xv About This Guide • Silicon Graphics Prism systems A server module must have one of the following operating systems installed: • SGI ProPack for Silicon Graphics Prism platforms • IRIX 6.5.11 or later for other platforms OpenGL Vizserver supports clients running the following software platforms: • IRIX 6.5.11 or later • Red Hat Linux 8 or later • SUSE LINUX 9 or later • Fedora Core 2 or later • SGI ProPack • Solaris 2.6 or later • Windows NT 4.0 , Windows 2000, and Windows XP • Mac OS X 10.3.5 or later Related Publications The following documents contain additional information that may be helpful: • SGI OpenGL Vizserver User’s Guide • Performance Co-Pilot User’s and Administrator’s Guide • IRIX Admin: Networking and Mail • IRIX Admin: Software Iinstallation and Licensing • SGI ProPack for Linux Start Here • SGI Scalable Graphics Compositor User’s Guide • Silicon Graphics Scalable Graphics Capture PCI-X Option User’s Guide xvi 007-4481-011 About This Guide Obtaining Publications You can obtain SGI documentation in the following ways: •

  • Visualisation of Dual Doppler Lidar Data
    Copy: of 23 Improved Air Quality Forecasting Invest to Save Report ISB52-08 Visualisation of Dual Doppler Lidar data By S Siemen and AR Holt University of Essex 6th November 2003 QinetiQ Copyright 2003 Authorisation Prepared by Dr RI Young Title Visualisation of Dual Doppler Lidar data Signature Date Location QinetiQ Malvern Principal authors Dr S Siemen Appointment Senior Research Officer, Dept. Of Mathematical Sciences University of Essex Principal authors Prof AR Holt Appointment Professor, Dept. Of Mathematical Sciences Location University of Essex 2 Record of changes Issue Date Detail of Changes 0.10 23/09/2003 Draft release for partner comments 1.00 06/11/2003 First Release 3 ABSTRACT This report ISB52-08 was produced under Project 52 of the Invest to Save Scheme, or ISB. The objective of this project is to improve the ability of air quality forecasts and thus impact on the quality of life in and around urban areas. As part of the project, the Propagation and Remote Sensing Research Laboratory at the University of Essex undertook a study to determine how the measured lidar data and the retrieved products can be best visualised. For this purpose a software suite, called DAViS, was developed, which could load lidar data and then visualise it by two-dimensional plots and on an interactive three-dimensional display. The software also allows interactive processing and display in real-time. The report describes the DAViS software and how it can be used to visualise Lidar data and retrieved products. Examples of the visualisation produced by DAViS are also included.
