Abstract: Plant simulation is a popular and difficult issue in computer graphics these years.
In order to conveniently and quickly browse the 3D plant which is realistic and interactive on web,
a mathematic model of plant-modeling based on determination L-system, parameter L-system and
the original recursive algorithm is proposed from the aspect of the plant physical structure in this
paper. X3D and JAVA are chosen to generate a three-dimensional plant model quickly and easily
after giving related parameters. The modeling of the branch structure of tree, the leaf arrangement
and leaf is realized in this paper.

Key words: computer application, fractal tree, parameter Lindenmayar system, physiological
structure
