SCEC VDO

SCEC Virtual Display of Objects (SCEC VDO)

Researchers and interns at the Southern California Earthquake Center (SCEC) have built a seismic data visualization software tool called the SCEC Virtual Display of Objects (SCEC-VDO). Written in Java with the Swing GUI toolkit to create interactive menus and the Visualization Toolkit (VTK) to render 3D content, SCEC-VDO allows for the visualization of 3D earthquake and fault objects on maps and the creation of images and movies for analysis, presentation, and publication.

Troubleshooting

macOS

As of SCEC-VDO v0.1.0, the macOS application is bundled as a zip file instead of an app file. macOS GateKeeper refuses to execute applications bundled this way by default, regardless of codesigning. We'll consider bundling a proper macOS app instead of a zip file as a permanent solution.

macOS "java cannot be opened" error

macOS app will not run because it's bundled as a zip file

Unauthorized applications cannot be directly executed in the Terminal or opened by double-clicking without making a GateKeeper exception. This is a very simple, one time process that should not take longer than a minute.

To create a security exception, you need to enable Developer Tools and allow the Terminal permission to bypass the system security policy. Enable Developer Tools by running spctl developer-mode enable-terminal and quitting the Terminal. Then navigate to Developer Tools inside System Settings, enable the Terminal to bypass security, and try running the SCEC-VDO application.

I've created video demonstrations showing exactly how to do this.

Linux

For our Linux users, the launch_linux.sh script installs the dependency freeglut3-dev using the Aptitude package manager. For users of non-Debian based distributions, you must install an equivalent with your package manager or compile from source.
