Requirements for installing and running LA3D

LA3D was written in Java and, like any Java program, requires that the proper environment be set up correctly before it can be run. The following steps should be closely followed, in order, to assure a successful installation of LA3D:

Installation Instructions:

1) Download and install the Java Runtime Environment (JRE) version 1.4.2 or greater (here)
  • [10.07.04] Note for MAC users: To date, our MAC users have not needed to install a JRE, but do need to obtain Java3D. However, you must have OS 10.3 or newer (else Java3D will not run). Also, you will need a 3-button mouse to navigate LA3D. These are inexpensive (< $20) and can be connected to USB ports.

    2) Download and install Java3D version 1.3.1 (here)
  • [10.07.04] Java3D requires that the JRE (step 1, above) be installed first!

    Versioning Criteria:

    0.1.x Version 0.1.x has limited functionality and was meant to serve simply as an open-source viewer of SCEC Community Fault Model (CFM) faults
    1.0.x Version 1.0.x can also be used as a fault viewer but additionally provides almost all of the datasets and functionality of the LA3D software package, excluding those features that require internet access such as earthquake animations and recent earthquake data
