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.

Key Features

Describes the algorithms and underlying data structure of OpenVDB
Provides actual implementation details for all level set concepts in the book
Presents real-world examples of Open VDB applications in VFX productions
Contains everything needed to adopt OpenVDB to new projects in the VFX industry, academic research, games development, and medical imaging
