Abstract

A facility for semantics-guided non-photorealistic rendering is described. In various embodiments, the facility receives a set of objects that are to be rendered in a non-photorealistic manner. For each received object, the facility determines whether the object has an associated indication of a feature type and, when the object has an associated indication of a feature type, employs a transformation function corresponding to the indicated feature type to render the object in a non-photorealistic style provided by the transformation function.

Claims

1. A method performed by a computer system for semantics-guided non-photorealistic rendering of images, comprising:

receiving a set of objects that are to be rendered in a non-photorealistic manner;

for each received object, determining whether the object has an associated indication of a feature type; and

when the object has an associated indication of a feature type, employing a transformation function corresponding to the indicated feature type to render the object in a non-photorealistic style provided by the transformation function.

2. The method of claim 1 wherein the objects are defined in a data file.

3. The method of claim 1 wherein the objects are defined in a vector format.

4. The method of claim 1 wherein the associated indication is a label.

5. The method of claim 4 wherein the label appears in an input file defining the objects.

6. The method of claim 1 wherein the associated indication is received from a user.

7. The method of claim 1 further comprising rendering the object in the style and adding the rendered object to a graphics layer.

8. The method of claim 1 wherein the rendering is performed procedurally.

9. The method of claim 8 wherein the object is rendered with stochastic variations.

10. The method of claim 1 wherein the rendering is performed by transforming an image.

11. A computer-readable medium having computer-executable instructions that perform a method for semantics-guided non-photorealistic rendering of a set of objects, the method comprising:

for each object in the set of objects, determining whether the object is indicated to be associated with an object type; and

when the object is indicated to be associated with an object type,

identifying a transformation function corresponding to the indicated object type; and

invoking the transformation function to render the object in a non-photorealistic style provided by the transformation function.

12. The computer-readable medium of claim 11 wherein the indication is a label identifying the object type, the label appearing in an input defining the set of objects.

13. The computer-readable medium of claim 11 further comprising:

rendering the object in the non-photorealistic style provided by the transformation function to render the object; and

adding the rendered object to a graphics layer.

14. The computer-readable medium of claim 11 further comprising identifying a generator component that provides the transformation function.

15. The computer-readable medium of claim 11 wherein the object is defined by an input file comprising at least control points and labels identifying a type of the object.

16. A system for semantics-guided non-photorealistic rendering of an image representing a set of objects, comprising:

a set of generator components that each generate a graphics layer for an object type; and

a rendering component that determines whether an object has an associated type and invokes a function provided by one of the generator components to render a non-photorealistic graphics layer corresponding to the object.

17. The system of claim 16 further comprising an input data file comprising at least objects and labels associated with the objects, the labels for identifying object types.

18. The system of claim 17 wherein the rendering component determines whether an object has an associated type by evaluating a label associated with the object.

19. The system of claim 18 wherein the generator component is identified in rendering information received by the rendering component.

20. The system of claim 18 wherein style information is identified in rendering information received by the rendering component and the rendering component identifies a generator component based on the received style information.
