Xfrog 是德国 Greenworks 公司的著名植物制作插件，是世界上唯一一个可以表现植物生长的插件 ，因其库文件价格昂贵 所以使用的人很少.

制作植物形态模型生长的软件 , 是完全使人信服的树木、花草建造软件，并能很容易被建造和使用，还能作其模型并生长....《 时间机器 》电影一片中的草原树木生长镜头就是这个软件作的。

XFrog是用来创建有机类组织结构的3D软件，其主要用来对如树，花朵，灌木丛，有机迭代体系结构，概念有机体进行建模及动画的创作。是世界上唯一一个可以方便地表现植物生长的软件。这是maya8的windowns版本。

Xfrog 4.1 adds six new procedural Objects to Maya. By combining these with Maya components/objects you can create a wide variety of organic models and animations using organic procedures (based on some of the building blocks of Nature).

Our tools behave exactly like Maya components, so you can keyframe them and combine them with PaintEffects or Particle animations or use MEL Scripts to drive them - the possibilities are nearly endless.

	Branch Object - create multi-level branching structures with extensive parameters to allow you to give them a natural look and feel..
	Phyllotaxis Object - arrange components on an abitrary surface of revolution, according to the rules of nature (golden section). It is, for example, used in the sunflower screenshot above to arrange petals and seeds.
	Hydra Object arranges components in user defined specialized circular patterns.
	Curvature Object creates Splines which can be used as a basis for naturally curved leafs or twigs.
	Variation Object allows you to use and multiply different Objects with the Branch, Phyllotaxis and Hydra Objects, for example you can use different leaves scattered throughout a tree, or any sort of variations that you need for higher realism.
	Tropism Object lets your spline-based objects or works created with the Branch Object, all bend towards a gravity or light point. e.g. all branches bending downward in a very specific way or reaching upwards towards light. keyframe this during Growth animations.
