摘要： A modeling system for easy designing three-dimensional models of crops by using component-based describing structure and step by step designing guidance is presented. The system uses B-splines curves to describe the skeleton of crop organs, and the geometry of an organ is then generated from its skeleton. Basing on these organs models, an interactive modeler has been developed to help users to create, edit the crop structure quickly. The design process includes parameterized generating of topological structure of crop, adjusting the main vine and details editing. Realistic appearance of the generated 3D models is improved by using texture mapping and including hairs that cover many plant organs. We demonstrate that our method handles the complexity of crops structure by creating different 3D crops.
