WELCOME TO Introduction to Computer Graphics, a free, on-line textbook covering the fundamentals of computer graphics and computer graphics programming. This book is meant for use as a textbook in a one-semester course that would typically be taken by undergraduate computer science majors in their third or fourth year of college. Version 1.3 contains significant updates from Version 1.2 of January 2018, including an update of the three.js material to release number 129, the addition of some material on WebGL 2.0, and an update of Appendix B to Blender 2.93. See the preface for more information.

The web pages for this book include live, interactive demos that require a modern web browser such as recent versions of Chrome, Firefox, Safari, or Edge. You might have to experiment to find a browser in which the demos will work well. While the book is mainly designed for reading on a desktop computer, most of the demos should also work on recent mobile devices, using a touchscreen instead of a mouse.
