releases beginning in 2006 included subdivision surfaces (Catmull–Clark algorithm–based polygon smoothing), scripting via the Lua programming language, and rendering to Photoshop layers. This release offered new subdivision tools, scripting support, bones and IK system, and a history palette. The Strata 3D CX v4.x releases in 2004 included Polygon modeling tools and Subdivision Surface modeling (SDS). In 2002, Strata 3Dbase and Strata 3Dpro (version 3) added functionality such as toon rendering and photon mapping. By 1999, Strata StudioPro 2.53 offered numerous new features, including a choice of QuicDraw 3D or OpenGL for onscreen rendering, multiple viewing options to speed up redraws as well as the ability to convert 3D primitives into skin, Bézier, polygon mesh objects. Other features included texture previews, path extrude, boolean operations, skin (loft) and extrude; and special effects such as fountains, lens flare, fog, mist Strata StudioPro 1.75 Blitz in 1996 added support of QuickDraw 3D, multiprocessor support, VRML export and the Raytracing renderer. In 1993 Strata StudioPro 1.5 was added to the product line, with StrataVision remaining a reduced-feature "light" version. StrataVision 2.0 introduced the Raydiosity rendering algorithm (a variant of radiosity) along with more powerful modeling features, faster rendering, basic animation and extensibility. StrataVision was released as the first product of the Strata company in 1988 to facilitate professional 3D graphics on regular desktop Macs. This first release provided high-end modeling and 3D rendering tools.
