Japanese Patent JP2006172134

Kind Code:

A

Abstract:

To provide a technology with which the value of a signed distance from a boundary being the basis of a level set method is more quickly calculated than with a conventional manner.

A signed distance corresponding to a node group on a segment XA connecting the position of a node X and the position of the nearest node A or in its neighborhood is calculated according to a following formula; d(Y)=d(X)|YA|/|XA| when d(X) is defined as a signed distance at the node X, and |XA| is defined as the length of the segment XA (S104).
