Essential Skills in Character Rigging / Edition 1

by Nicholas B. Zeman

Overview

Character rigging is the method with which you create a system for animating a character. A rig is represented by two primary mechanics: the skeleton, consisting of hierarchical rotations to drive the motions, and a skin, or method of deforming the geometry that makes up the character model. Essential Skills in Character Rigging is a beginner’s guide to learning and understanding the essential aspects of character setup, evaluation, skeletal construction, and deformation. Borrowing from the author’s extensive experience in the field, it presents the primary theories, constructs, and objectives for constructing a basic rig from the ground up, just as it would be done in a professional studio.

The book explains the basic elements of hierarchies, skeletons, kinematics, deformation, skinning, and creating relationships between nodes. It gives hands-on experience with taking a completed character model and setting it up with a skeleton with kinematics and soft-skin deformation. It also gives specific instructions on using inverse kinematics systems, and how to set up the essential mechanics of a human rig with these systems. All of these lessons are conducted using a simplistic, conversational style that keeps technical and mathematical jargon to a minimum. The book also includes video tutorials corresponding to specific modules.

Essential Skills in Character Rigging takes aspiring character artists through the vital components in the process of taking a 3D character model and turning it into an animatable rig that is ready for production in film or games. It identifies the universal fundamentals at work behind character rigging, and the practical complexities of the process are broken down into simple steps that are easy to comprehend and execute.

About the Author

Nicholas B. Zeman started his career in 3D graphics at the University of Kentucky, Lexington, where during graduate school he began working at 3D Studio Max. He left Kentucky for San Diego, where he was offered a job at Red Zone Interactive, a then-small company making the NFL Gameday series for Sony Computer Entertainment. He continued working for them as an expert in character rigging, facial rigging, and facial animation after they were purchased by Sony Computer Entertainment America, until the team was disbanded and the NFL Gameday series was canceled. He was later hired by Take Two Interactive in San Rafael, where he continued to develop and manage character rigs for the NBA 2K series, All-Pro Football 2K8, MLB 2K9-10, and NHL 2K9. After almost 12 years in character rigging for sports games, he left employment as a game developer to focus on the academic pursuit of interactive development. He became a professor at Northern Kentucky University in the Media Informatics Department and began his own digital media technology company, RHZ Development LLC, where he consults and produces functional games through gamification, mobile apps, and mobile games under the studio brand Little Fish Games and RHZ Development.
