1. A tetra mesh generator comprising:
- an input unit to which shape definition data that defines a three-dimensional shape is input; and
a processing unit that disposes a plurality of particles on an edge and a surface of the three-dimensional shape defined by the shape definition data input to the input unit, disposes particles according to an internal distribution rule in an inner part spaced apart from the surface of the three-dimensional shape, disposes particles at a position deviated from the position according to the internal distribution rule, in a space between the inner part and the surface of the three-dimensional shape, and generates a tetra mesh having a center of the disposed particles as a vertex.

Abstract
An input unit to which shape definition data that defines a three-dimensional shape is input. A processing unit disposes a plurality of particles on an edge and a surface of the three-dimensional shape defined by the input shape definition data, disposes particles according to an internal distribution rule in an inner part spaced apart from the surface of the three-dimensional shape, disposes particles at a position deviated from the position according to the internal distribution rule, in a space between the inner part and the surface of the three-dimensional shape, and generates a tetra mesh having a center of the disposed particles as a vertex.
