| dc.description.abstract | The visual simulation of plants involves two major areas of computer graphics research: geometrical modeling and lighting modeling. Clearly, the first step to visualize a plant is to geometrically model its shape and structural characteristics. The next step is to simulate its interaction with light in order to determine appearance attributes such as color, glossiness and translucency. This step corresponds to the main stage of the rendering pipeline. After all, our perception of any object depends on how it scatters or absorbs light. Viewed in this context, the understanding of the natural processes involved in light interaction with plants is not only central to the simulation of their appearance, but it is also essential for the simulation of their growth and their interaction with the surrounding environment. In this tutorial the main physical and biological aspects involved in the processes of reflection, transmission and absorption of light by plants are addressed. The formulation of virtual measurement devices used to verify the accuracy of reflectance and scattering models is also presented. Computer graphics models of light interaction with plants are examined in detail to allow their implementation and incorporation into rendering frameworks by computer graphics researchers and skilled practitioners. Finally, open problems and current trends in this area are discussed. The focus of this discussion will be on the generation of more realistic images of natural scenes through the use of more comprehensive and efficient reflectance and transmittance models for plants. | en_US |
