Three-dimensional simulation method and apparatus

A three-dimensional simulation method comprising:

• determining whether a sheet flexible object model formed of first polygons in three-dimensional simulation space interferes with another object model;
• forming second polygons by dividing the sheet flexible object model in a longitudinal direction when determining that the sheet flexible object model interferes with the other object model;
• and
• determining a shape of the sheet flexible object model using the formed second polygons in consideration of a shape of the other object model, by a computer.

A three-dimensional simulation apparatus comprising:

• a memory configured to store form information of a sheet flexible object model formed of first polygons and another object model;
• a processor configured to execute to:
• determining whether the sheet flexible object model formed of the first polygons in three-dimensional simulation space interferes with the other object model on the basis of the form information stored in the memory;
• forming second polygons by dividing the sheet flexible object model in a longitudinal direction when it is determined that the sheet flexible object model interferes with the other object model;
• and
• determining a shape of the sheet flexible object model using the formed second polygons in consideration of a shape of the other object model.
