Method for automatically moving object in simulation system and simulation system using the same

A simulation system for a dental application comprising:

• a display unit configured to display a plurality of objects, the plurality of objects being obtained from a dental arch image of a subject and being three-dimensional (3D) objects:
• a memory configured to store an object distance measuring program for measuring a vector distance between the objects;
• a user input unit configured to generate a movement signal for a first object of the plurality of objects;
• and
• a control unit configured to:
• execute the object distance measuring program stored in the memory to measure a vector distance between the first object and a second object which is adjacent to the first object based on an expected movement of the first object,
• based on the vector distance, automatically vector-move the second object that is adjacent to the first object, in the simulation system, by a predetermined distance in a first direction along a predetermined dental arch path until the vector distance between the first object and the second object is in a preset vector distance range, thereby resulting in automatic alignment of the plurality of objects with one another on the predetermined dental arch path,
• automatically move a third object which is an object adjacent to the second object so that the third object is in the preset vector distance range from the second object by the control unit according to the automatic movement of the second object,
• extract intersection points at which the plurality of 3D objects and a reference surface having a plane equation intersect with each other by the control unit,
• convert the 3D objects into two-dimensional (2D) objects using the intersection points by the control unit, and
• set a 2D path that is determined using center points of the 2D objects to the present path by the control unit,
• wherein the predetermined distance is smaller than the vector distance, and display the moved objects on the display unit, when the first object of the plurality of objects moves in the first direction based on the movement signal input through the user input unit and
• wherein the automatic vector-moving of the second object includes, based on the vector distance, determining whether the first object and the second object either overlap with or spaced apart from each other.
