INTViewer 4.3 Evaluation Guide

Thank you for evaluating INTViewer 4.3. Below you will find  useful tips to help  install, configure, and run INTViewer, plus highlights of some of the important features you don't want to miss during your evaluation.

Installation

  1. Make sure Java SE 1.6 is  installed (can be downloaded from http://www.oracle.com/technetwork/java/javase/downloads/index.html). If no software development is to be done, download the JRE, otherwise select the JDK version. Note: if you have a 64bit machine, you may want to install a 64bit version of Java.
  2. Install Java 3D 1.5.2 (can be downloaded from http://java3d.java.net/binary-builds.html). Make sure to select the  version (32/64bit) that matches your java installation.
  3. Install INTViewer
          • double click on file INTViewerInstaller.jar
          • Or run command java -jar INTViewerInstaller.jar
  4. Copy the license file (license.dat) into the main folder where you have installed INTViewer

Running INTViewer

  • On Windows:
    If you checked “create additional shortcuts on the desktop” option when installing INTViewer, then just double click on the INTViewer icon in your desktop. Otherwise, you will find the INTViewer command in the Start-Menu.
  • On Linux:
    If you checked “create additional shortcuts on the desktop” option when installing INTViewer, then just double click on the INTViewer icon in your desktop.  Otherwise, navigate to the INTViewer installation in a terminal window and execute command ./INTViewer.sh.

Memory Configuration

By default, INTViewer is set up to use a maximum of 1GB of memory. This should be fine in most cases, even if you are dealing with very large seismic datasets. However, this may not be sufficient if you are trying to load large horizon files or want to load a large volume in memory. If you have installed a 64bit version of java, you can edit the startup script (INTViewer.sh on Linux or INTViewer.bat on Windows) and look for the line:

.\bin\intviewer.exe -J-da -J-Xms128m -J-Xmx1g

If you want, let say to use a maximum of 4GB, simply replace the “1” by a “4”. Make sure this number is smaller than the amount of physical memory in your machine.

Plugins

INTViewer has a plugin architecture and INT maintains a site that contains many optional plugins for INTViewer. To view and download those plugins, check the option Tools->Plugin and go to the tab Available Plugins. You will be able to select and install any additional plugin that you may need.

Features you should not miss

  • Indexing – INTViewer will directly load most seismic file formats such as Segy, SU, JavaSeis, SEP, etc. However to take full advantage of the random access capability of the viewer (inlines, crosslines, gathers, arbitrary slices, etc.) for most  formats it is necessary that you index your data. Please check the indexing tutorial.
  • Transpose – To access time slices in a map view or a 3D volume without loading the volume in memory you will need to transpose it. Please see the transpose tutorial
  • XSection and Map views - A basic tutorial on creating XSection and Map views check the cube tutorial.
  • 3D Viewer – To learn more about the 3D viewer, check the 3D tutorial. Also the 3D Quick Guide gives a short list of useful tips to navigate in a 3D view.
