Space is a free MS
2K, XP [Vista, W7 not tested]) application for the display, navigation,
and measurement of 3-D data sets. In many respects it serves the same
needs as a traditional 2-D image editor for 3-D data, but is organized
optimized for the particular requirements of handling 3-D data for
research purposes. The program provides fast display of arbitrarily
oriented planes through 3-D data, direct spatial correlation and
combining of multiple spatially coincident data sets, several image
processing operations, and an array of fully interactive display and
rendering options for visualization. All primary functions, display
and user interaction elements are highly integrated.
Space is authored by Mark Dow and Greg
Scott, and is
currently in active, but slow, development. Space is freeware (in the free
lunch sense), but the source code is not publicly available.
The current beta-testing
versions expired at the end of December 2010, but still operates

Several program details and advanced
tools are still
being perfected, and a few ragged edges will be trimmed in the coming
months. The core operations are stable and well tested.
