Level Set Methods in Computer Graphics A Practical Approach Based on OpenVDB
Auteur : Museth Ken
The level set method is a numerical technique for tracking interfaces and shapes with which one can perform numerical computations to create curves and surfaces. Recently released as a free, open source project, OpenVDB is an efficient tool for manipulating and storing volumes of creative data, such as smoke and similar amorphous materials. This book presents an easily accessible, yet comprehensive foundation of level sets and offers descriptions of advanced applications of level sets and OpenVDB from actual movie productions.
