Abstract

Page turning of a three-dimensional electronic book is modeled as a dynamic animation. The page to be turned may be rotated by rotating it about a base line, and deformed by curling points of the front face of the turning page around the outer side of an imaginary geometric shape.

Claims

1. A method for turning portions of an electronically represented three-dimensional object, comprising:

animating a turning of a turning portion of the three-dimensional object;

wherein the animation includes deforming the turning portion by curling at least a part of the turning portion about an imaginary geometric shape; and

wherein the curling includes mapping a point on the turning portion to a point on the imaginary geometric shape.

2. The method of claim 1, wherein the imaginary geometric shape has a curved surface.

3. The method of claim 2, wherein coordinates of the point on the imaginary geometric shape are calculated based on a cone angle and a location of a cone apex.

4. The method of claim 3, wherein, for different frames of the turning, the cone angle is different, and the location of the cone apex is different.

5. The method of claim 1, further comprising:

separating the three-dimensional object into the turning portion, a first non-turning portion and a second non-turning portion, the first and second non-turning portions being connected to the turning portion at first and second connections, respectively; and

maintaining the first connection and the second connection while animating the turning of the turning portion.

6. The method of claim 1, wherein the three-dimensional object is an electronic document, and the turning portion includes at least one page of the electronic document.

7. The method of claim 6, wherein the turning portion comprises multiple pages of the electronic document, turned as a single block.

8. The method of claim 7, wherein a size of the single block is determined based on user input indicating a number of pages to be turned at once.

9. A computer readable storage medium on which is recorded a set of instructions for performing the method of claim 1.

18. The controller of claim 3, wherein the three-dimensional object is an electronic document, and the turning portion includes at least one page of the electronic document.

19. The controller of claim 18, wherein the turning portion comprises multiple pages of the electronic document, turned as a single block.

20. The controller of claim 19, wherein a size of the single block is determined based on user input indicating a number of pages to be turned at once.

10. A method for turning portions of an electronically represented three-dimensional object, comprising:

receiving user input indicating a location on the object; and

animating a turning of a turning portion of the three-dimensional object;

wherein the animation differs depending on the location indicated by the user.

11. The method of claim 10, wherein the three-dimensional object is an electronic document, and the turning portion includes at least one page of the electronic document.

12. A computer readable storage medium on which is recorded a set of instructions for performing the method of claim 10.

13. A controller for turning portions of an electronically represented three-dimensional object, the controller animating a turning of a turning portion of the three-dimensional object;

wherein the animation includes deforming the turning portion by curling at least a part of the turning portion about an imaginary geometric shape; and

wherein the curling includes mapping a point on the turning portion to a point on the imaginary geometric shape.

14. The controller of claim 13, wherein the imaginary geometric shape has curved surface.

15. The controller of claim 14, wherein coordinates of the point on the imaginary geometric shape are calculated based on a cone angle and a location of a cone apex.

16. The controller of claim 15, wherein, for different frames of the turning, the cone angle is different, and the location of the cone apex is different.

17. The controller of claim 13, wherein the controller:

separates the three-dimensional object into the turning portion, a first non-turning portion and a second non-turning portion, the first and second non-turning portions being connected to the turning portion at first and second connections, respectively; and

maintains the first connection and the second connection while animating the turning of the turning portion.

21. A system including the controller of claim 13.

22. A controller for turning portions of an electronically represented three-dimensional object, the controller:

receiving user input indicating a location on the object; and

animating a turning of a turning portion of the three-dimensional object;

wherein the animation differs depending on the location indicated by the user.

23. The controller of claim 22, wherein the three-dimensional object is an electronic document, and the turning portion includes at least one page of the electronic document.

24. A system including the controller of claim 23.

25. A method for turning portions of an electronically represented three-dimensional object, comprising:

animating a turning of a turning portion of the three-dimensional object;

wherein the animation includes deforming the turning portion by curling a first part of the turning portion about a first imaginary geometric shape, and curling a second part of the turning portion about a second imaginary geometric shape; and

wherein the curling includes mapping a point of the first part of the turning potion to a point on the first imaginary geometric shape, and mapping a point of the second part of the turning portion to a point on the second imaginary geometric shape.

26. The method of claim 25, wherein the first imaginary geometric shape and the second imaginary geometric shape have an identical shape.

27. The method of claim 25, wherein the first part of the turning portion is a top face of a turning pages block and the second part of the turning portion is a bottom face of the turning pages block.
