Abstract
Provided is an area determination method for determining an area corresponding to an object from a three-dimensional model of an oral cavity. The area determination method includes: obtaining the three-dimensional model; determining a seed point on the three-dimensional model; based on the seed point, determining a reference point on the three-dimensional model; determining an area corresponding to an object, by gradually expanding a selection area based on the reference point; and displaying the determined area on the three-dimensional model.
Claims19
An area determination method for determining an area corresponding to an object from a three-dimensional model of an oral cavity, the area determination method comprising:
- obtaining the three-dimensional model;
- determining a seed point on the three-dimensional model;
- based on the seed point, determining a reference point on the three-dimensional model;
- determining an area corresponding to an object, by gradually expanding a selection area based on the reference point;
- and
- displaying the determined area on the three-dimensional model.
A three-dimensional model processing apparatus for processing a three-dimensional model of an oral cavity, the three-dimensional model processing apparatus comprising:
- a display displaying an image rendered from the three-dimensional model;
- and
- at least one processor configured to
- determine a seed point on the three-dimensional model,
- based on the seed point, determine a reference point on the three-dimensional model,
- determine an area corresponding to an object, by gradually expanding a selection area based on the reference point, and
- control the display to display the area determined on the three-dimensional model.
An area determination method for determining an area from a three-dimensional model, the area determination method comprising:
- obtaining a three-dimensional model of an oral cavity;
- determining at least a partial area of an area to be selected in the oral cavity;
- based on the determined at least partial area, determining, from the three-dimensional model, a first area corresponding to the area to be selected;
- and
- displaying the determined first area.
