A computer graphics software development company. Founded in 1984, merged with Microsoft in 1994, bought by Avid in 1998. Sold from Famous for its DS, 3D, XSI, and behavior products. Flagship product is XSI (the name comes from the period when Softimage was sold to Microsoft, adopting a DirectX API, hence the X; the SI is self-explanatory), arguably the most advanced CG package on the market. Marketed aggressively, albeit to the detriment of Softimage's prestige. Its other (important) app is behavior, which is a massive crowd simulator.
Softimage revamped their image lately. Before, they used to be unbelievably prestigious, now they're rather common.
If CG software were car brands:
Blender - Scion
Cinema 4D - Audi
3ds Max - Ford
Maya - BMW
XSI - Maybach
