Softimage/XSI.(Software Review)(Evaluation)

A 1.0 release with promise

After many years and two changes of ownership, Softimage finally released its long-awaited successor to Softimage|3D. The software codenamed Sumatra now goes by the name of Softimage|XSI, and it includes many of the company's high-end animation tools, plus a nice user interface and numerous new features including scripting, paintable deformations, and nonlinear animation. The software comes in two versions: the Essentials package, reviewed here, and Softimage|XSI Advanced, which includes integrated particles, soft bodies, and an additional Mental Ray license.

For any software company, a ground-up rewrite such as this is painful. Like a newly constructed building, Softimage|XSI's architecture is there, but not all the features have moved in yet. Some of those waiting to be added are polygonal modeling with subdivision surfaces, a dope sheet, and advanced NURBS modeling tools such as trims and blends. A few are already slated for inclusion in Version 1.5, which was in beta at press time.

Seasoned Softimage users should take to the new interface--which includes features such as object orientation and floating windows--fairly quickly. As in Softimage|3D, most functions are accessed through a series of buttons running vertically along the left side of the application.

Those familiar with object-oriented packages such as Maya, Max, and Houdini will be happy that Softimage is now part of the club. Most tools, including deformations, are nondestructive and are manipulated through Softimage's Properties panel, enabling you to tweak object modifications at any time.

Other interface tweaks include the ability to float windows such as the Scene Explorer, Schematic window, and Animation Editor above the workspace. You also can create and add custom toolbars at will.

Scripting is a new feature that enables you to write custom scripts and interfaces quickly and easily. To create a custom button, for example, simply highlight the commands and drag them to a toolbar. For custom script writing, Softimage|XSI supports several standard languages, including Perl, VBScript, and Java Script.
