Method, apparatus, storage medium and program for generating image data of virtual space

1. A method for generating image data of a virtual space viewed from a predetermined view point, comprising:

determining a boundary of a predetermined plane area in the virtual space;

providing a line object having one boundary line portion which is at least one portion of the boundary of the predetermined plane area and having a predetermined width towards an inside of the predetermined plane area; and

changing the width of the line object while a position of the one boundary line portion of the line object remains fixed.

2. The method as claimed in claim 1 , wherein the changing the width of the line object comprises changing a width of one end portion of the line object and a width of the other end portion of the line object separately.

3. The method as claimed in claim 1 , wherein the changing the width of the line object comprises changing the width of the line object on the basis of at least one of a position, a depression angle, an eyes direction and a view angle of the view point.

4. The method as claimed in claim 1 , wherein the changing the width of the line object comprises changing the width of the line object on the basis of at least one of a distance between the view point and the plane area and a distance between the view point and the line object.

5. The method as claimed in claim 1 , wherein the changing the width of the line object affects regenerating the image data of the virtual space.

6. The method as claimed in claim 1 , further comprising: inclining the line object at a predetermined angle while the position of the one boundary line portion remains fixed.

7. The method as claimed in claim 1 , wherein the line object comprises at least one of a straight line object and a curved line object.

8. The method as claimed in claim 7 , wherein the one boundary line portion is at least one side of the boundary when the line object is a straight line object.

9. The method as claimed in claim 1 ,

wherein the providing the line object comprises providing an internal line object having one line portion and another line portion each of which is not one portion of the boundary, and a predetermined width; and

the changing the width of the line object comprises changing the width of the internal line object by moving both the one line portion and the another line portion.

10. The method as claimed in claim 1 , wherein the virtual space is a game space of a predetermined game.

11. A method for generating image data of a virtual space viewed from a predetermined view point, comprising:

determining a boundary of a predetermined plane area in the virtual space;

providing at least one line object having at least one line portion and having a predetermined width on the basis of the boundary; and

changing the width of the line object by moving the at least one line portion of the line object.

12. An apparatus comprising:

an image generating section for generating image data of a virtual space viewed from a predetermined view point;

a determining section for determining a boundary of a predetermined plane area in the virtual space;

a providing section for providing a line object having one boundary line portion which is at least one portion of the boundary of the predetermined plane area and having a predetermined width towards an inside of the predetermined plane area; and

a changing section for changing the width of the line object while a position of the one boundary line portion of the line object remains fixed.

13. The apparatus as claimed in claim 12 , wherein the changing section changes a width of one end portion of the line object and a width of the other end portion of the line object separately.

14. The apparatus as claimed in claim 12 , further comprising a game execution unit for executing a predetermined game according to image data of a game space of the predetermined game, which is generated by the image generation section as the virtual space.

15. A storage medium having a program recorded thereon, when the program is loaded onto an operating apparatus, the program making the operating apparatus execute the method as claimed in any one of claims 1 to 6 .

16. A program, when the program is loaded onto an operating apparatus, to make the operating apparatus execute the method as claimed in any one of claims 1 to 6 .
