Abstract
Abstract A method and system for drawing and designing highly complex and subtly-colored images with a very small amount of user input. By choosing this input, the graphic designer has full control over the shape and its colorization. The shape and its colorization are created independently. In this way, the graphic designer can easily create stylized geometric and natural forms. One embodiment is as a software program on a digital computer. The input can be given by direct manipulation. With this invention, the designer can create shapes with great detail that would be impractical to draw with existing tools. The method grows a complex image in steps. Starting with an initial template consisting of a number of components, the template is transformed by replacing one component by a transformed version of the same or another template. The replaced component is colorized. The colorization is a function of the original color of the component and the color path associated with the replacement template. These steps are repeated until the drawing is sufficiently detailed. An embodiment on a digital computer can do millions of steps, resulting in stylized natural and geometrical images of great detail and complexity.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
88 words
A method to draw a generated shape comprising: (a) drawing a template of said generated shape; (b) choosing a component of the drawing and a replacement template, both according to a predetermined choice function, where said choice function is used substantially to provide fine control over complexity, density, and texture of said drawing; (c) replacing said component by a transformed copy of said replacement template; and (d) repeating steps (b) and (c), together referred to as an iteration, until no further components are given by said choice function.
Claim 2
Independent Claim
88 words
A method to draw a generated shape comprising: (a) drawing a template of said generated shape; (b) choosing a component of the drawing and a replacement template, both according to a predetermined choice function, where said choice function is used substantially to provide fine control over complexity, density, and texture of said drawing; (c) replacing said component by a transformed copy of said replacement template; and (d) repeating steps (b) and (c), together referred to as an iteration, until no further components are given by said choice function.
Claim 3
Dependent Claim
55 words
The method of claim 1 extended to draw a generated image and to that end further comprising: (a) choosing a color path for each template in said image; and (b) during each said iteration, combining the color of said component with the color path that corresponds to said replacement template, using a predetermined mixing function.
Claim 4
Dependent Claim
24 words
The method of claim 2 wherein said transformed copy represents one or more of a scaling, rotation, deformation, and simplification of said replacement template.
Claim 5
Dependent Claim
17 words
The method of claim 2 wherein each template includes a set of components that are line segments.
Claim 6
Dependent Claim
27 words
The method of claim 2 wherein the first part of said choice function is selected from the group consisting of recursive replacement with deltas and threshold replacement.
Claim 7
Dependent Claim
28 words
The method of claim 2 wherein said mixing function is a weighted arithmetic average of the color of said component with the color path of said replacement template.
Claim 8
Dependent Claim
15 words
The method of claim 2 wherein said image is defined by more than one template.
Claim 9
Dependent Claim
24 words
The method of claim 1 wherein said transformed copy represents one or more of a scaling, rotation, deformation, and simplification of said replacement template.
Claim 10
Dependent Claim
17 words
The method of claim 1 wherein each template includes a set of components that are line segments.
Claim 11
Dependent Claim
27 words
The method of claim 1 wherein the first part of said choice function is selected from the group consisting of recursive replacement with deltas and threshold replacement.
Claim 12
Dependent Claim
15 words
The method of claim 1 wherein said shape is defined by more than one template.
Claim 13
Independent Claim
74 words
A system to define a generated image that comprises: (a) a graphical representation for a template component; (b) user-interface tools to combine instances of said graphical representations into representations of templates; (c) user-interface tools to select a choice function that is used for drawing said image; (d) user-interface tools to define the color path corresponding to each template; and (e) user-interface tools to select a mixing function that is used for drawing said image.
Claim 14
Independent Claim
74 words
A system to define a generated image that comprises: (a) a graphical representation for a template component; (b) user-interface tools to combine instances of said graphical representations into representations of templates; (c) user-interface tools to select a choice function that is used for drawing said image; (d) user-interface tools to define the color path corresponding to each template; and (e) user-interface tools to select a mixing function that is used for drawing said image.
Claim 15
Dependent Claim
14 words
The system of claim 12 wherein the user-interface tools are based on direct manipulation.
Claim 16
Dependent Claim
17 words
The system of claim 12 wherein each template includes a set of components that are line segments.
