1. A modeling apparatus, comprising:

  • a memory configured to store positional information of a plurality of points; and

    a processor coupled to the memory and configured to execute a process, the process comprises;

    first calculating a first function for generating data of a closed surface that contains the plurality of points that represent an annular structure in an object, based on the positional information of the plurality of points;

    generating data of a first point set that represents a boundary of the object, from data of a plurality of tomographic images in each of which a first area occupied by the object is designated;

    detecting data of points which are included in the first point set and located inside the closed surface by using the first function;

    removing the detected data of points from the data of the first point set to generate data of a second point set;

    second calculating a second function for generating data of a shape of the object using the data of the second point set and data of the plurality of points; and

    storing data of the shape of the object, which is generated by using the second function, in the memory.
