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 The book is based on original and hitherto unpublished research.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 areutilized 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.
