based on their research into natural systems and systematic processes found in nature.

Overview

Xfrog was developed to be an intuitive modeling method and GUI for creating natural branching structures based on the rules of nature. Structure and geometry is encapsulated in objects that form the description of the model. To define a model, icons (graphic representations of components) are assembled in a graph depicting the model’s structure and hierarchy, beginning with a root icon. Models are saved in the proprietary Xfrog .xfr format, a text file that contains the complete set of parametric rules for the procedural "Frog"engine to interpret and draw the polygonal model.

and Disney Imagineering. Xfrog 1.0 did not contain key frame or procedural recursive animation capabilities, but in 1998 Xfrog 2.0 introduced animation capabilities. It was released for the first time as a plugin for Maya 1.0 making Greenworks the first professional plugin developer for Maya. The stand-alone application was ported from SGI to Windows and introduced as Xfrog 3.0 at SIGGRAPH 2000. In 2006, Xfrog’s first Cinema 4D plugin, Xfrog 4 for Cinema 4D, added all the components of 3.5 to the Cinema 4D interface.xfrog.com "History" http://xfrog.com/company/history/ Currently, both the Cinema 4D and Maya plugins are at version 5.2.
