Midnight Mars Browser version 1.2 introduces the Panorama feature, which allows you to explore an environment composed of rover images. This is still a work in progress, so consider the Panorama feature to be in an experimental stage. Use at your own risk. I'm releasing it now because I know there are some people out there who want to see it if it's not completely polished.
Java 3D is required to use the new feature, so read the updated installation instructions for the link to go download and install it. The program should function without Java 3D if you don't need to use the Panorama feature.
At the moment pans are only defined for Sols 1 through 270 on both rovers. The next thing I'll be working on is tools to quickly create panoramas for sols after 270, for which complete data hasn't been released by NASA/JPL.
