Introduction to IRIS Explorer^TM

What Is IRIS Explorer?

IRIS Explorer is a powerful visual programming environment for 3D data visualisation, animation and manipulation. It is a standards-based package that utilises the Open Inventor^TM, ImageVision^TM and OpenGL^TM libraries together with NAG's world-class numerical libraries. It is available on a broad range of PC and workstation platforms (see Getting More Information below).

IRIS Explorer's visual programming environment enables you to create customised applications simply by selecting from the library of ‘modules’ (software routines) included and connecting them together, without writing a single line of code. The application can be altered and updated just as simply. This enables you to interactively analyse collections of data and visualise the results for analysis, presentations or publication. Each module is interactively controlled by a set of dials, buttons, sliders and file browsers, which are displayed on a control panel and can be altered while the application is running.

You can develop your own modules or use NAG's Consultancy Service (External) to write modules tailored to your particular requirements. These modules provide an easy way to share functionality, without the need to understand the underlying program or algorithm.

What Is the History of IRIS Explorer?

IRIS Explorer was originally developed and distributed by Silicon Graphics, Inc. (SGI). Interest in the system grew over the years and SGI decided to move IRIS Explorer to an external independent software house. On 25th July 1994 the Numerical Algorithms Group (NAG) took over the development, porting, marketing, sales and support of IRIS Explorer from Silicon Graphics. NAG have subsequently made a number of enhancements to the product.

Documentation

• On-line
  The on-line IRIS Explorer documentation is included with the product installation in hyper-text (HTML) format. It can be viewed using a standard web-browser such as Netscape Navigator or Microsoft Internet Explorer. The on-line docmentation comprises:
• IRIS Explorer Tutorial Guide (this document)
• IRIS Explorer User's Guide
• IRIS Explorer Module Writer's Guide
• IRIS Explorer Collaborative User Guide
• IRIS Explorer Reference Pages (help for each module and interface call)

These documents are also available on the World Wide Web and can be found at:


http://www.nag.co. uk/visual/IE/iecbb/DOC/Index.html (External).

• Printed
  The following printed manuals are available from your nearest IRIS Explorer Center (External):
• IRIS Explorer Tutorial Guide (this document)
• IRIS Explorer User's Guide
• IRIS Explorer Module Writer's Guide
• IRIS Explorer Collaborative User Guide


• Additional Documents
  The following additional documents may be obtained via your IRIS Explorer Center (External):
  • IRIS Explorer Technical Overview
    Technical summary of architecture of system
  • IRIS Explorer Technical Report Series (External)
    User-contributed papers on working with IRIS Explorer
  • Render - The Newsletter for IRIS Explorer Users
    Distributed through the IRIS Explorer Centers

Training

To help you get the most from IRIS Explorer, NAG runs two comprehensive, hands-on training courses (External) for current and potential users of IRIS Explorer.

• Getting Started with IRIS Explorer
  This two-day course shows you how to start building and using applications to visualise your data. No knowledge of IRIS Explorer or programming is assumed. The course describes what IRIS Explorer does, how data is represented within the system, how to construct applications from software building blocks (modules), and how to read data into IRIS Explorer. The course cost includes comprehensive notes and lunch.

• Working with IRIS Explorer
  This two-day course enables you to learn the more advanced features of the software. In particular, it focuses on building new modules to extend the functionality of the system. It is assumed that the user has a working knowledge of IRIS Explorer (or has attended the Getting Started with IRIS Explorer training course) and can program in C and/or Fortran 77. The course describes some of the advanced features of the Map Editor, the module building environment, and the IRIS Explorer data types in detail. It also describes Shape, an interpreted language which can be used to quickly build and prototype new IRIS Explorer modules. The course cost includes comprehensive notes and lunch.

These courses are available in Europe, North America and Japan. They can also be arranged for other parts of the world. Further information including prices and scheduled course dates can be obtained from your nearest IRIS Explorer center (see Getting More Information below).

Consultancy Services

NAG offers a consultancy service which can range from short-term module writing through to full application implementations. The modular nature of IRIS Explorer means that it is easy for NAG IRIS Explorer consultants to customise the product to meet your particular needs.

Modules can be developed for range of requirements, such as

• developing customised format file readers
• porting existing legacy C or FORTRAN code into IRIS Explorer
• adding new visualisation techniques
• tailoring the mathematical algorithm set

In addition, the Consultancy Service can, for example

• develop fully specified applications
• provide "on the job" training
• run training events (using the NAG training facilities or your location)
• provide technical input for projects involving IRIS Explorer
