Getting Started

Before you can start exploring agricultural relationships in 3D, the correct components must be installed on your machine.

System Requirements:

Cortona Browser

  • Operating system: Microsoft® Windows® 95/98/ME/2000 or Windows NT® 4.0
  • Other software: Internet Explorer 4.0 or higher or Netscape Navigator 3.01 or higher (4.0+ recommended), RealPlayer (for playing Real Video and Real Audio).
  • Computer: Pentium® 90 MHz or better
  • Random Access Memory (RAM): minimum of 16 MB
  • Free disk space: 6 MB of hard disk space for program files
  • Display: SVGA. The 800x600, high color mode and higher
  • Interface: Mouse and keyboard
  • Sound card: optional

GeoVRML

  • Operating system: Microsoft® Windows® 95/98/ME/2000, Windows NT® 4.0, Mac, Unix, Linux
  • Other software: Internet Explorer 4.0 or higher or Netscape Navigator 3.01 or higher (4.0+ recommended), RealPlayer (for playing Real Video and Real Audio).
  • Computer: Pentium® 90 MHz or better
  • Random Access Memory (RAM): minimum of 16 MB
  • Free disk space: 3 MB of hard disk space for program files
  • Display: SVGA. The 800x600, high color mode and higher
  • Interface: Mouse and keyboard

Software Requirements:

GeoVRML 1.1 Runtime Environment(website)
  •   The GeoVrml Runtime Environment interprets the code for the 3D models and allows the model to be displayed.

    Cortona VRML Client(    website)
  •   The Cortona VRML Client is a plug-in for internet browsers that allows the ability to view GeoVRML files. Cortona has built in functions that easily allow the user to navigate in the 3-D model. For more info on this check out the learning section of this manual

    Java Virtual Machine(website)
  •   Java is a computing platform from Sun Microsystems. Java technology enables just about any application to run on just about any computer or device. If you don't already have it, you will need it to enjoy the 3D models.


    • Flash Player(website) Optional
  •   Macromedia Flash allows integration of video, text, audio, and graphics resulting in superior presentations and application interfaces. You can navigate the IFAFS website without flash but it is highly recommended and can be obtained by clicking here.

    • IFF Tool     Optional
  •   The IFF Tool is a set of functions which focus on speed and functionality. The tools included are: DBF2IFF, Kriging and Geo-VRML. The format used for IFAFS Data is called IFF. The IFF file extension is “.IFF”. It is a binary file, although some of the data is saved in ASCII text. The main three parts of the fire are: Signature, Metadata, and Data. DBF2IFF is a filter that translates dbf files into IFF files. Kriging is used to interpolate the data that later will be used by the GeoVRML tool to generate 3D images to be displayed in internet.

    • Installation
    :

  • You must download and install GeoVRML1.1, Cortona and Java Virtual Machine (JVM) included in the link below:
    Program Zip File

  • You can also download install the IFF tool if you want to create GeoVRML files
    IFF Tool Installer
    •  

    Important: Once the installation is completed restart your computer.
