Modélisation de fruits, de leur structure interne et de leurs défauts

Abstract : One of the largest areas of research in computer graphics deals with natural phenomena representation. Over the years, as our understanding of nature grew, researchers started to propose new ways of simulating the various natural phenomena that we can observe in our everyday life. In this thesis, we focused on the representation of fruits. The fruit is a complex object. Depending on the desired accuracy, modeling a 3D fruit using classic 3D modeling software can become very tedious. We propose a model for generating vast varieties of fruits as well as their internal structure, thanks to the use of a single formal grammar. Each fruit that will be generated using our method will have global features that characterize its species, but it will also have local variations that are specific to it. The second part of ou work involves the representation of geometrical imperfections along the fruit. The fruit is the result of a series of physiological processes that strongly interact with each other. When one of these processes does not work the way it should, this dysfunction is materialized in the form of a shape defect. Our model introduces a simple approach, based on the use of grammars, which will allow us to apply variations on fruits in order to generate various categories of shape defects.
