Abstract

Design software can be configured to allow a user in real-time to adjust a depth of field of a perspective of the user within a design space. In one implementation, for example, the design software can receive one or more inputs from a user regarding a layout of one or more objects in a design space. The design software can also render a three-dimensional model of the layout of the design space for display on a computerized display. The software can then receive from the user one or more input selections regarding a desired depth of field of the perspective of the user relative to one of the one or more objects rendered within the three-dimensional model. In addition, the design software can calculate revised rendering instructions that blur at least a portion of the design space. Furthermore, the design software can display, in real-time, the three-dimensional model with the desired depth of field to the user.

Claims

1. In a computerized architectural design environment in which a design program is loaded into memory and processed at a central processing unit, a computer-implemented method for allowing a user in real-time to adjust a depth of field of a perspective of the user within a design space, the method comprising:

receiving one or more inputs from a user regarding a layout of one or more objects in a design space;

rendering a three-dimensional model of the layout of the design space for display on a computerized display;

receiving from the user one or more input selections regarding a desired depth of field of the perspective of the user relative to at least one specified object of the one or more objects rendered within the three-dimensional model;

calculating revised rendering instructions that blur at least a portion of the design space based on the global position of the at least one specified object; and

displaying, in real-time, the three-dimensional model with the desired depth of field to the user, the global position of the at least one specified object remaining the same, the depth of field being maintained relative to the at least one specified object during navigation of the three-dimensional model.

2. The method as recited in claim 1, further comprising:

receiving from a user an indication to save information about at least one particular perspective within the three-dimensional model.

3. The method as recited in claim 2, wherein the information about the at least one particular perspective comprises depth of field information.

4. The method as recited in claim 3, wherein the information about the at least one particular perspective comprises durational information that indicates a viewing duration of the particular perspective.

5. The method as recited in claim 4, further comprising:

creating, in real-time, a movie file or interactive flythrough file based upon at least one bookmark;

wherein the movie file or interactive flythrough comprises the particular perspective, depth of field, and duration that is associated with the at least one bookmark.

6. The method as recited in claim 1, further comprising receiving from the user input regarding the layout of the design space.

7. The method as recited in claim 1, further comprising:

creating, in real-time, a movie file or interactive flythrough of the perspective of the user within the three-dimensional model

wherein the perspective of the user within the three-dimensional model comprises the desired depth of field.

8. The method as recited in claim 1, wherein receiving from the user one or more inputs regarding the desired depth of field comprises receiving from the user an indication of a distance to a focus plane.

9. The method as recited in claim 1, wherein receiving from the user one or more inputs regarding the desired depth of field comprises receiving from the user an indication of a depth factor.

10. The method as recited in claim 1, further comprising allowing the user to interpolate between two or more depth of field settings.

11. The method as recited in claim 1, further comprising displaying in real-time changes, interpolations, or animations of the depth of field effect applied to the three-dimensional model, as the user navigates through the layout or plays back the movie file.

12. In a computerized architectural design environment in which a design program is loaded into memory and processed at a central processing unit, a computer-implemented method for allowing a user in real-time to create a movie file or interactive flythrough of one or more scenes while adjusting a depth of field of the one or more scenes, the method comprising:

receiving from the user one or more inputs regarding a layout of the design space within the architectural design environment, the design space including one or more objects;

rendering a three-dimensional model of the layout of the design space within the architectural design environment;

creating a movie file or interactive flythrough in real-time showing various aspects of the three-dimensional model;

receiving from the user one or more inputs regarding adjustments to the depth of field for at least one specified object of the one or more objects of the one or more scenes from the perspective of the user within the three-dimensional model; and

capturing within the movie file or interactive flythrough in real-time the adjustments to the depth of field of one or more scenes, the global position of the at least one specified object remaining the same, the depth of field being maintained relative to the at least one specified object during navigation of the three-dimensional model.

13. The method as recited in claim 12, further comprising:

creating a bookmark;

wherein the bookmark comprises information associated with a particular perspective within the three-dimensional model.

14. The method as recited in claim 13, wherein the bookmark further comprises depth of field information associated with the particular perspective within the three-dimensional model.

15. The method as recited in claim 14, wherein the bookmark further comprises durational information, which indicates an amount of time that should be spent viewing the particular perspective, and the amount of time that should be spent flying to the location.

16. The method as recited in claim 15, further comprising:

creating, in real-time, a movie file or interactive flythrough based upon one or more bookmarks;

wherein the movie file or interactive flythrough comprises the particular perspective, depth of field, and duration that is associated with the one or more bookmarks.

17. The method as recited in claim 12, wherein receiving from the user the one or more inputs regarding adjustments to the depth of field comprises receiving from the user an indication of a distance to a focus plane.

18. The method as recited in claim 12, wherein receiving from the user the one or more inputs regarding adjustments to the depth of field comprises receiving from the user an indication of a depth factor.

19. The method as recited in claim 12, further comprising:

positioning the at least one blur plane based upon a location of a focus plane and a shallow factor or deep factor;

determining a blur-plane distance, wherein the blur-plane distance is a measurement between a specific point within the three-dimensional model and the at least one blur plane; and

calculating the blurriness of the specific point based upon the blur-plane distance, the pixel sample number, and the pixel sample distance.

20. A computer program product for use at a computer system, the computer program product for implementing a method for allowing a user in real-time to adjust a depth of field of a perspective of the user within a design space, the computer program product comprising one or more computer storage media having stored thereon computer-executable instructions that, when executed at a processor, cause the computer system to perform the method, including the following:
