I've released SaVi 1.4.0.
The SaVi 1.4.0 release includes new features:
- satellite names
- shows sun lighting on coverage.
- vastly improved high-performance coverage texturemap piping to Geomview.
- varying (1-19) levels of coverage shading, useful for viewing high-diversity constellations such as GPS and Galileo
- can save high-resolution renderings and screen snapshots of the Geomview camera, either singly or in sequence for postprocessing to make movies.
SaVi 1.4.0 is compatible with Tk 8.5, latest gnu make and gcc, and Mac OS X Leopard/XCode 3.0.
