X frog is developed by Greenworks Organic Software for the use of interactive modeling and animation of natural branching structures like trees, f10wers and plants. XFrog is a stand¬alone program which includes the basic li¬brary, an XfrogPlants Library of twenty species of common trees and three age variations of each tree that contains sixty models.

The 'PhiBall' has fan, radius and angle settings and the 'Trees' has stem, branches and tropisms settings. You can animate all these components by varying their parameters like number of branches. strength and gravity. Presently two types of packages are available in the market. If you want to make both anima¬tions and modeling. choose XfrogFul1. If you are planning to do modeling only, then go to XfrogLite. In this hands-on, we show you how to create 'Grisella' with few simple steps.
