摘要
Generate a mesh model representing a natural blood vessel shape. Based on the blood vessel information (11a), the biological model generation device (10) targets each of the plurality of nodes (P11, P12, P13) through the target node (P11, P12, P13) and the center line (1). A first circle (3) having a first radius obtained by adding an allowable error value to the radius of a blood vessel on a plane (2a, 2b, 2c) perpendicular to A second circle (4) having a second radius obtained by subtracting the allowable error value from the radius and having the target node as a center point is provided. Next, the biological model generation device (10) generates a plane (2a, 2b, 2c) passing through each of the plurality of nodes (P11, P12, P13) and a second circle (4) inside the first circle (3). Generate an implicit function that defines the outer intersecting surface (7). Then, the biological model generation device (10) generates a mesh model (8) based on the curved surface (7) defined by the implicit function.
