Abstract
We present a modeling method that allows easy generation of various crop organs including leaves, fruits, caudexes, petioles and even nonbotanical things. B-splines curve has been used to describe the skeleton of these organs, then the geometry of an organ is generated from its skeleton. The model can be modified interactively by editing the shape of the skeleton and the silhouette in 3-D to control the overall shape of an organ. The users get immediate feedback on what they’ve created model. Realistic appearance of the generated organ is improved by using texture mapping and including hairs that cover many plant organs. We demonstrate that our method handles the complexity of most real plant organs. Basing on these organs models, we develop a simple but efficient method for constructing crop structure. An interactive modeler has been developed to help users to model, edit the organs and crop structure quickly. We demonstrate the flexibility of our approach by creating different organs and crops structure.
