In computer-aided 3d animation and modeling there are some burning issues. Such as, how hair visualization will be handled in a scene; how cloth will act; how trees or vegetation will take place etc. Especially and at least, people of the 3d industry desires- they should have nice trees in their scenes. May be, men are the child of the nature and in the lap of nature trees are their best and smartest friends.

There are several vegetation systems in 3d faculty. One is modeled Mesh system (being a headache for the scene for its complexity and also time consuming business). Another is just mapping of photograph-done pictures of tree onto billboard. I respect all the existing systems of vegetation.

However, I am now presenting a system which is something in-between of the above-mentioned two systems.
