Paper Title
Initial Interface of Level Set Method based on Oriented Bounding Box and Pseudo-Normal Vector

This paper proposes a method of initial interface modeling for moving boundary by level set method in a 3D grid space. The initial interface is represented by signed distances from an interface to grid points. This paper finds the initial interface only in the narrow band using oriented bounding box, and weighted pseudo-normal vector without involving Eikonal method. The proposed method was implemented and compared with Eikonal method using a sphere and Stanford common 3D test models. The results show that the proposed method can decrease more distance errors than Eikonal method in a particular environment.
