1. A method of modeling objects, the method comprising:
- detecting an adjacent area shared by modeled particles of a first object and modeled particles of a second object, where one or more particles of the first object are adjacent to one or more particles of the second object in the adjacent area;
defining a grid with respect to the adjacent area;
calculating an action force between the first object and the second object in the adjacent area based on information stored for grid points of the grid; and
modeling the first object and the second object based on the calculated action force.

Abstract
Provided is a method and apparatus for modeling objects that may include detecting an adjacent area that shares modeled particles of a first object and modeled particles of a second object, calculating an action force between the first object and the second object in the adjacent area based on information stored for grid points of a grid defined with respect to the adjacent area, and modelling the first object and the second object based on the calculated action force.

15. An apparatus for modeling objects, the apparatus comprising:
a processor configured to perform a grid converting operation to detect an adjacent area sharing modeled particles of a first object and modeled particles of a second object and to define a grid with respect to the adjacent area, and configured to perform an object modelling operation to calculate an action force between the first object and the second object in the adjacent area based on information stored for grid points of the grid and to model the first object and the second object based on the calculated action force. - View Dependent Claims (16, 17, 18, 19)

20. An apparatus for modeling objects, the apparatus comprising:
-
a memory configured to store a program to control an operation of the apparatus; and at least one processor configured to execute the program to control the processor to detect an adjacent area sharing modeled particles of a first object and modeled particles of a second object, to define a grid comprising a plurality of cells with respect to the adjacent area, to calculate an action force between the first object and the second object in the adjacent area based on information for grid points of the grid, and to model the first object and the second object based on the calculated action force.

21. A method of modeling objects, the method comprising:
-
detecting an adjacent area sharing modeled particles of a first object and modeled particles of a second object; selectively modifying shapes or motions of the first and second objects, for particles of the adjacent area, based on calculated reactionary forces between detected colliding particles of the first object and the second object in the adjacent area and in response to collisions being determined to occur in cell units of the adjacent area; and selectively modifying positions of particles of the first object outside of the adjacent area based on repulsive forces applied to the particles of the first object outside of the adjacent area for collision avoidance. - View Dependent Claims (22)
