Realistic rendering of plants has practical value for digital plant research, where plant leaves play an important role in the construction of virtual plants. The fact is that plant leaves are diversified in structure and geometric shape, which usually makes the realistic rendering of plants leaves very difficult. Many existed modeling and simulation methods have been focused on the organs of plant models, in which leaves are modeled using simple 2D polygons and the thickness of leaves are neglected. Such models are far from realistic. This paper proposes a new modeling method of broad-leaf plants, based on the theory of reverse engineering. A leaf model is established by acquiring data on the characteristic points from the leaf of the sample part and combining the advantages of OpenGL and NURBS functions.
