3D mathematics is a subject related to computational geometry. 3D math is the technical basis of computer graphics and computer 3D game development, while computational geometry is a subject that studies how to solve geometric problems with numerical methods. Both 3D math and computational geometry are widely used in fields that use computers to simulate the 3D world, such as graphics, games, simulations, robotics, virtual reality, animation design, and more.

For over 50 years, Thomas' Calculus series of books have a new edition available averagely every four, five years. Each edition has many improvements based on previous ones, which embodies this is a teaching material full of innovation spirits. At the same time, some basic characteristics of this book have been always kept and increased, which shows that it is a textbook attaching great importance to inheritance of teaching tradition.
