Fractal-based 3d tree modeling

In this paper, we propose an approach for generating three dimension (3D) models of trees base on fractal idea that has the benefit of offering automatically and interactively modeling. The approach can generate 3D geometry tree using botanical knowledge and the fractals, can automatically generate photorealistic tree in real-time, also provides the capability for the user to control shape of the tree in a parameterized way as compared with rule-based tree modeling systems. The approach is very useful in practices and generates visually convincing results.
