The 3D Moiré Effect - Weissman, Yitzhak

. .

Résumé :
The 3D moir? effect creates an impressive 3D illusion that doesn't require any visual aids to observe. Although it has been known for a while, it has recently gained more attention due to advancements in printing technologies that allow for commercial and artistic exploration. Initially, it was used to produce images of floating planes. Gradually, it has been discovered that the surface can be sculpted into various forms, like a hemisphere, which has opened up new applications and increased interest in the effect. This book explains the theoretical foundations of the 3D moir? effect and how to sculpt the display into different surface geometries. It provides numerical and analytical methods for the computation of the image-warping transformation involved in the sculpting process. The book is based on original and hitherto unpublished research. It explores two types of 3D moir? assemblies: optical and parallax-barrier. The optical category offers superior imaging and visual qualities and involves optical micro-lens arrays like lenticular and fly-eye sheets. The parallax barrier assembly is made from purely mechanical components. Throughout the analysis, several new concepts are presented, which might require considerable effort from the reader to grasp. To make the process easier, the matter is unveiled gradually, step by step. Firstly, moir? setups that exhibit floating planes are thoroughly analyzed. Then, the sculpting theory is introduced to generalize the floating planes scenario. To aid in comprehension, numerous figures and examples are utilized in the text to guide the reader. It's important to note that creating 3D moir? pictures requires both theoretical knowledge and specific software and production processes, so readers looking to learn that skill may not find what they're looking for in this book. However, for those interested in exploring the topic on a theoretical level or writing software for 3D moir? applications, this book is a valuable resource. The concluding chapters briefly discuss the relation of 3D moir? setups with 3D lenticular and fly-eye pictures and the new concept of 3D moir? optics....

Biographie:
Dr. Yitzhak Weissman received his Ph.D. degree from Tel Aviv University in 1981. Since then, his career interleaved scientific and applied research. During his academic activity, Dr. Weissman published over 30 scientific papers and two books: Optical Network Theory in 1991, and Lenticular Imaging in 2018. The subjects of his publications include solid-state physics, quantum mechanics, optical fibers, infra-red technology, optical noise, optical engineering, and heat transfer. Dr. Weissman spent two sabbatical periods in the US: in the UC Berkeley Chemistry Department in 1981 as a post-doctoral fellow, and in the University of Utah Electrical Engineering Department in 1991 as a visiting Professor. Dr. Weissman's passion for innovation and entrepreneurship has led him to participate in numerous start-up projects, which included the development of fiber-optic sensors, infra-red spectroscopy instrumentation, simulator displays, optically efficient polarizers for projection 3D displays, diamond color grading, and lenticular print. Dr. Weissman's involvement in 3D visualization started with stereo photography. His lenticular printing service of stereo photographs became very popular among stereo photographers around the world. The work on lenticular stereo pictures led him to the study of 3D lenticular imaging, which is documented in his book Lenticular Imaging. The work on this subject shifted Dr. Weissman's attention to the more sophisticated 3D photography, and to a branch of 3D digital art called Virtual Sculpture. Nowadays, he is an active artist in these fields. Dr. Weissman was born in Poland in 1949. In 1957 he immigrated with his family to Israel. He is married, has two children, and lives in Herzliya, Israel....
