The plant modeling research based on improved 3D L-system and quaternion

This paper describes the plant modeling research based on improved 3D L-system and quaternion. It first introduces the original 3D L-system and how to implement it, then brings forward the improved modeling method of 3D L-system by specifying the growth vector and azimuth vector and applies the quaternion based computer algorithm in it, in the end generates some 3D plant models of sympodia and uniaxiality based on the improved method and algorithm.
