Abstract

There is provided a system and method for a computerized animation system comprising a series of images stored in a memory storage structure. These images are comprised of picture elements, and the memory storage structures comprise a plurality of bit planes, which are further divided into at least two storage structures. A first storage structure is used for storing operator-modified image information in a vector representation, and a second storage structure is used to store a raster representation of the operator-modified image information. The system can display multiple images from the second storage structure to facilitate the creation of additional images.

Claims

1. A computerized animation system, comprising means for creating a series of images, each image defined by a set of vector values and means for storing said series of images in a memory structure for storing image information, means for displaying said images as a plurality of pixels and said memory structure comprising a plurality of bit planes and sub-divided into at least two storage structures, a first storage structure in which is temporarily stored operator-modified image information as a set of vector values and a second storage structure comprised of at least one bit plane, in which is stored a raster representation of said operator-modified image information in said at least one bit plane of said second storage structure.

2. The computerized animation system of claim 1 wherein said image stored in said first storage structure is displayed on a display device in an operator-selected color.

5. The computerized animation system of claim 1 wherein the image stored in said bit planes is displayed on a display device in an operator-selected color.

3. The computerized animation system of clam 1 wherein said second storage structure is comprised of four bit planes.

4. The computerized animation system of claim 3 wherein each of said images stored in each of said bit planes is displayed in an operator-selected color associated with said bit planes.

6. A computer-based method for creating animated images comprising the steps of:

a) creating and displaying a first image, said first image comprised of vector-defined lines and stored as a set of vector values in a first memory location of a vector storage structure;

b) converting said first image into a raster defined image and temporarily storing said first image in a first memory location of a first raster storage structure as a raster-defined image;

c) creating and displaying a second image, said second image comprised of vector-defined lines and stored as a set of vector values in a second memory location of said vector storage structure;

d) converting said second image into a raster defined image and temporarily storing said second image in a second memory location of said first raster storage structure as a raster defined image;

e) creating and displaying a third image representing a transition from said first image to said second image, said third image comprised of vector-defined lines and stored as a set of vector values in a third memory location of said vector storage structure; and

f) converting aid third image into a raster defined image and storing said third image in a third memory location of said first raster storage structure as a raster defined image.

7. The method of claim 6 wherein said first image is displayed while said second image is created.

8. The method of claim 6 wherein said first image and said second image are displayed simultaneously while said third image is created.

9. The method of claim 8 wherein said displayed first image is displayed in a different color than said second image.

10. The method of claim 9 wherein said displayed first image is displayed in a first color, said displayed second image is displayed in a second color, and said third image is displayed in a third color.

11. The method of claim 6 further comprising the step of repeating steps a) through f) with said third image created in step e) becoming a new first image.

12. The method of claim 6 further comprising the step of repeating steps a) through f) with said third image created in step e) becoming a new second image.

13. The method of claim 6 wherein the temporarily stored images are each stored in separate second raster storage structures with a gray-scale value assigned to each bit plane.

14. The method of claim 13 wherein each separate second raster storage structure corresponds to one frame of an animated sequence of images.

15. The method of claim 14 wherein the images stored in the separate second raster storage structures are cycled and displayed on a display device to show animation.

16. The method of claim 15 wherein the cycling of the images is done automatically at a preselected rate in a preselected direction.

17. A computerized animation system, comprising means for creating a series of images, each image defined by a set of vector values and means for storing said series of images in a memory structure for storing image information, means for displaying said images as a plurality of pixels and aid memory structure comprising a plurality of bit planes and sub-divided into at least two storage structures, a first storage structure in which is temporarily stored operator-modified image information as a set of vector values and a second storage structure comprised of at least a first and a second bit planes, in which is stored a raster representation of said operator-modified image information in first and second said bit planes of said second storage structure, wherein said image information stored in said first bit plane and said image information stored in said second bit plane are displayed simultaneously.
