This is the first book to provide current knowledge of biophysically-based models of light interaction with plants aiming at realistic image synthesis of plants. These models were developed using computer graphics techniques and biological data. The modeling approach involves the use of rendering algorithms, such as ray tracing and Monte Carlo Methods, to simulate light propagation within plant tissues. The same research methodology described in the book can be applied to other organic materials such as skin, hair and eye tissues. Since the processes of light interaction with plants are central in environmental studies, scientific applications also include projects towards ecology, agriculture, forestry and remote sensing. The authors describe these processes and how they determine plant appearance characteristics such as color, gloss and translucency. The authors discuss how computer models can be used to investigate plant interaction with the environment.
This is the first book to provide current knowledge of realistic visual images of plants aiming at physical and biological accuracy by using computer techniques and biological data. It involves two areas of computer graphics (geometrical modelling and lighting modelling) to create model images of plants and biological materials. Scientific applications include organic substances like human skin and hair, and also remote sensing. The authors explain how plant life interacts with light, determining the characteristics of colour, gloss, lustre, reflectant haze and translucency, and even growth and interaction with the environment. They address biological and physical aspects involved in reflection, transmission and absorbtion of light by plants, and explain the formulation of devices used to obtain reflectance and scattering measurements for plants. Computer models of light interaction with plant life are described in detail for researchers in computer graphics, biology, remote sensing and related areas. No other book in this area has before been published.
