Preface

Human evolution is tied to the process of collecting, processing, transferring, and recording information. If people gain most of their most information visually, then computer graphics is one of the generational changes in computer technology. Creating a book on computer graphics is quite challenging given its actual range. Nevertheless, in this book, modern approaches, procedures, algorithms, as well as devices in the area of light and colors, shading and lighting, realistic and photorealistic imaging, definition of graphical scenes or objects, and security based on graphical objects are presented. The book also covers graphical transformations and projections, spatial imaging, curves and surfaces, filling and texturing, image filtering, virtual reality, color imaging and graphics in the service of light-source design, and analytical methods for reflection and refraction, as well as area of visualization. Topological visualization techniques for volume multifield data and "cosmos visualization" and usage of advanced related technologies such as virtual reality and graphics-based security can also be found in this book, whether it's topdown historical reconstruction in virtual reality or new graphical password schemes

Finally, I would like to express my gratitude to all the authors for their valuable contributions and professional efforts in providing such precious content.
