Abstract
This introductory chapter motivates the book through a discussion of the many sources and applications of geometric data.
Small to medium sized objects can be captured with a variety of optical acquisition techniques, such as laser scanning, structured light scanning, and time of flight cameras. There are many uses of optical acquisition, and number of these are medical in nature: for instance, laser scanning has emerged as an important part of in-the-ear hearing aid manufacturing.
At the other end of the scale spectrum, airborne laser scanning allows us to build digital terrain models and ultimately city models. Finally, a lot of geometric data are still produced manually through the use of CAD software.
Going through each topic, we discuss what geometry processing algorithms are pertinent and refer the reader to the chapters where these algorithms are discussed in greater detail.
