Plants simulation is a important studies project in the computer graphics. We discussed the "Bamboo" simulation modeling which is involved in very few researchers. We improved the I= system algorithm based on the "Bamboo" singlcaxis plant characteristics,and explained the relevant different tcchnicals and methods used in "Bamboo" modeling and the realistic performanc. We quoted the displacement texture mapping technique to solve the difficult problem simulating the section header of "bamboo". Through this method,you can simulate realistic "Bamboo" form and characteristics in the nature. This paper gave a new solution in plant simulation.
