System and method for generating an animatable character
View Patent ↗A system and method are disclosed for generating an animatable object. A skeleton of the desired character is constructed by the user utilizing various predetermined components. These predetermined components include a various selection of rods and joints. The rods are static components which remain rigid during motion, while the various joints are moveable components. A static digitized image, for example, an image of the user, is utilized and a constructed skeleton is superimposed onto it. The desired object, such as the image of the user, can then be extracted from the background of the digital image and the resulting personal character can then be animated, for instance by selecting and dragging one of the hands with a mouse.
1. A method for generating a character in a computer system comprising:
constructing a skeleton of a predetermined object;
superimposing the skeleton with a digital image wherein the digital image includes the predetermined object; and
preparing the digital image, wherein preparing the digital image includes performing background subtraction using a parameter of the skeleton.
2. The method of claim 1 further comprising determining a topology of the skeleton.
3. The method of claim 1 wherein the skeleton is constructed of at least one predetermined component.
4. The method of claim 3 wherein the predetermined component is a rod.
5. The method of claim 3 wherein the predetermined component is a joint.
6. The method of claim 5 wherein the joint is a center pin joint.
7. The method of claim 5 wherein the joint is a center radial joint.
8. The method of claim 1 wherein the character can be animated.
9. The method of claim 1 further comprising laminating a texture map to the skeleton.
10. The method of claim 1 further comprising adjusting a skeleton parameter to correspond with the predetermined object.
11. The method of claim 10 wherein adjusting includes adjusting the skeleton parameter to approximate a parameter of the predetermined object.
12. The method of claim 1 further comprising determining where a motion will occur.
13. The method of claim 1 further comprising transmitting data related to the generation of the character at a first time.
14. The method of claim 13 further comprising transmitting data related to animation of the character at a second time.
15. The method of claim 13 further comprising transmitting changes to the character at a second time.
16. The method of claim 15 wherein the changes include joint angles.
17. The method of claim 15 wherein the changes include body position.
18. The method of claim 15 wherein the changes include body rotation.
19. The method of claim 15 wherein the changes include changes in height and/or width.
20. The method of claim 1 wherein the character is a player on a network.
