Abstract

In various embodiments, a gradient modeling application automatically generates designs of three-dimensional (3D) objects. The gradient modeling application generates a set of points based on a resolution and a perimeter. The gradient modeling application computes a set of displacement values based on the set of points, a first two-dimensional (2D) border, and a first displacement parameter that is associated with the first 2D border. Based on the set of displacement values, the gradient modeling application generates a 3D object design.

First claim

What is claimed is:

1. A computer-implemented method for automatically generating designs of three-dimensional (3D) objects, the method comprising:
generating a plurality of points based on a resolution and a perimeter;
computing a plurality of displacement values based on the plurality of points, a first two-dimensional (2D) border, and a first value for a first displacement parameter that is associated with the first 2D border; and
generating a first 3D object design based on the plurality of displacement values.

2. The computer-implemented method of claim 1 , wherein the first 2D border comprises at least one of a 2D curve or a 2D point.

3. The computer-implemented method of claim 1 , wherein the first value for the first displacement parameter specifies a distribution defining a degree of influence that the first 2D border exerts on a 2D point based on a distance between the first 2D border and the 2D point.

4. The computer-implemented method of claim 1 , wherein computing the plurality of displacement values comprises computing a first displacement value by:
computing a first distance between the first 2D border and a first point included in the plurality of points; and
computing the first displacement value based on the first distance and the first value for the first displacement parameter.

5. The computer-implemented method of claim 1 , wherein computing the plurality of displacement values comprises computing a first displacement value by:
determining that a first point included in the plurality of points is influenced by the first 2D border based on a first 2D position of the first point; and
computing the first displacement value based on the first value for the first displacement parameter.

6. The computer-implemented method of claim 1 , wherein computing the plurality of displacement values comprises computing a first displacement value by:
computing a degree of influence that a set of 2D borders that includes the first 2D border has on a first point included in the plurality of points based on a first 2D position of the first point and the first value for the first displacement parameter; and
computing the first displacement value based on the degree of influence and a displacement limit associated with the set of 2D borders.

7. The computer-implemented method of claim 1 , further comprising:
receiving, via a graphical user interface (GUI), a user event corresponding to an interaction between a user and an interactive GUI element; and
determining the first 2D border or the first value for the first displacement parameter based on the user event.

8. The computer-implemented method of claim 1 , wherein generating the first 3D object design comprises modifying a displacement field associated with an overall surface based on the plurality of displacement values and at least one of a blending mode or a position of the perimeter within the overall surface.

9. The computer-implemented method of claim 1 , further comprising generating a displacement field based on the plurality of displacement values, a second 2D border, and a second value for the first displacement parameter.

10. The computer-implemented method of claim 1 , further comprising:
converting the plurality of displacement values to a bitmap; and
modifying a target portion of a target 3D object design based on the bitmap to generate a second 3D object design.

11. One or more non-transitory computer readable media including instructions that, when executed by one or more processors, cause the one or more processors to automatically generate designs of three-dimensional (3D) objects by performing the steps of:
generating a plurality of points based on a resolution and a perimeter;

12. The one or more non-transitory computer readable media of claim 11 , wherein the first displacement parameter comprises a maximum outward displacement or a maximum inward displacement.

13. The one or more non-transitory computer readable media of claim 11 , wherein the first value for the first displacement parameter specifies a line, a Bezier curve, or a Non-Uniform Rational B-Spline curve that defines a degree of influence that the first 2D border exerts on a 2D point based on a distance between the first 2D border and the 2D point.

14. The one or more non-transitory computer readable media of claim 11 , wherein computing the plurality of displacement values comprises computing a first displacement value by:
computing a first distance between the first 2D border and a first point included in the plurality of points; and
computing the first displacement value based on the first distance and the first value for the first displacement parameter.

15. The one or more non-transitory computer readable media of claim 11 , wherein computing the plurality of displacement values comprises computing a first displacement value by:
determining that a first point included in the plurality of points is influenced by a plurality of 2D borders that includes the first 2D border based on a first 2D position of the first point and the first value for the first displacement parameter; and
computing the first displacement value based on the first 2D position of the first point.

16. The one or more non-transitory computer readable media of claim 11 , wherein generating the first 3D object design comprises modifying a displacement field associated with an overall surface based on the plurality of displacement values and at least one of a blending mode or a position of the perimeter within the overall surface.
