Description: 《3D数学基础:图形与游戏开发》专业培训机构指定教学参考书,多家游戏开发企业共同推荐,游戏业界权威,探索游戏开发背后的核心秘密。《3D数学基础:图形与游戏开发》主要介绍了基本的3D数学概念,这对电脑游戏开发人员和编程人员来说尤为重要。作者详尽地讨论了数学理论,并在必要时提供几何说明,帮助读者形成直观的3D感。书中还提供了将理论应用于实践的C++类,并且在每章结尾处提供练习。《3D数学基础:图形与游戏开发》介绍了基础概念,如向量、坐标空间、矩阵、变换、欧拉角、齐次坐标空间、几何图元、相交性检测和三角网格。-This book is about 3D math, the study of the mathematics behind the geometry of a 3D world. 3D
math is related to computational geometry, which deals with solving geometric problems algorithmically.
3D math and computational geometry have applications in a wide variety of fields that
use computers to model or reason about the world in 3D, such as graphics, games, simulation,
robotics, virtual reality, and cinematography.
This book covers theory and practice in C++. The “theory” part is an explanation of the relationship
between math and geometry in 3D. It also serves as a handy reference for techniques and
equations. The “practice” part illustrates how these concepts can be applied in code. The programming
language used is C++, but in principle, the theoretical techniques from this book can be
applied in any programming language.
This book is not just about computer graphics, simulation, or even computational geometry.
