Surface selecting method and information processing apparatus
A surface selecting method in an information processing apparatus for selecting a prescribed surface of a 3D model displayed on a display unit of the information processing apparatus includes a display control step of controlling the display unit so as to display the 3D model, and a detection step of detecting an indication to an edge line formed by two adjoining surfaces of the 3D model displayed on the display unit. In addition, a determination step determines whether the indication is an indication to an edge line formed between a first surface and a second surface, wherein the first surface is not being displayed and the second surface is being displayed on the display unit, and a selection step selects the first surface, which is not being displayed on the display unit, if the indication is an indication to the edge line formed between the first and second surfaces.
1. A surface selecting method in an information processing apparatus for selecting a prescribed surface of a 3D model displayed on a display unit of the information processing apparatus, comprising:
a display control step of controlling the display unit so as to display the 3D model;
a detection step of detecting an indication to an edge line formed by two adjoining surfaces of the 3D model displayed on the display unit;
a determination step of determining whether the indication is an indication to an edge line formed between a first surface and a second surface, wherein the first surface is not being displayed and the second surface is being displayed on the display unit; and
a selection step of selecting the first surface, which is not being displayed on the display unit, if the indication is an indication to the edge line formed between the first and second surfaces.
2. The method according to claim 1 , further comprising a display step of displaying the first surface, which is not being displayed on the display unit, on the display unit in an identifiable manner if the indication is an indication to the edge line formed between the first and second surfaces.
3. The method according to claim 1 , further comprising a setting step of setting attribute information, which indicates a distance dimension, with respect to the first surface that has been selected.
4. An information processing apparatus for selecting a prescribed surface of a 3D model displayed on a display unit of the information processing apparatus, comprising:
display control means for controlling the display unit so as to display the 3D model;
detection means for detecting an indication to an edge line formed by two adjoining surfaces of the 3D model displayed on the display unit;
determination means for determining whether the indication is an indication to an edge line formed between a first surface and a second surface, wherein the first surface is not being displayed and the second surface is being displayed on the display unit; and
selection means for selecting the first surface, which is not being displayed on the display unit, if the indication is an indication to the edge line formed between the first and second surfaces.
5. A computer-readable storage medium encoded with a computer program for causing a computer to execute a surface selecting method set forth in claim 1 .
