Introduction to 3D Deep Learning

3D deep learning, i.e., deep learning with 3D data, has been attracting increasing attention due to its tremendous research values and broad real-world applications. In this paper, we first provide an overview of 3D data, its unique characteristics, and the challenges associated, as well as the wide range of applications of 3D data in various fields. We then introduce the fundamentals of 3D deep learning, including the basic concepts, the key technical challenges, the recent developments, and the emerging real-world applications of 3D deep learning.
