Abstract

A first user having a certain set of privileges with respect to an initial three-dimensional (3D) model associates a watermark with the initial 3D model, so that the watermark is displayed whenever the initial 3D model is viewed or edited. A second user having a smaller set of privileges with respect to the initial 3D model is permitted to view, copy and/or modify the initial 3D model, but is not permitted to remove or alter the content of the watermark. The watermark is continuously displayed as the second user works with the initial 3D model. When the second user applies a change to the initial 3D model, an indication of the modifications applied by the second user is generated and stored with the model data corresponding to the updated 3D model.

Claims

1. A method of controlling rights to three-dimensional models, comprising:

rendering, at a display device, an initial three-dimensional (3D) model and a first watermark, the first watermark corresponding to a first association between a first user and initial model data corresponding to the initial 3D model, the first watermark being indicative of rights of the first user to the initial model data, and the initial model data stored on a computer-readable medium;

receiving, via a user interface, a user-initiated command from a second user to modify a portion of the initial 3D model;

modifying, in accordance with the user-initiated command, a respective portion of the initial model data corresponding to the portion of the initial 3D model to form updated model data corresponding to an updated 3D model;

generating and storing a second association between the second user and the updated model data corresponding to the modified respective portion of the initial model data;

rendering the updated 3D model in conjunction with the first watermark and a second water mark corresponding to the second association between the second user and the modified respective portion of the initial model data, the second watermark being indicative of rights of the second user to the modified respective portion of the initial model data; and

preventing the second user from disassociating the first watermark and the updated 3D model.

2. The method of claim 1, further comprising:

receiving a request from the first user to secure the rights to the initial three-dimensional (3D) model, and in response to the request, generating a rights indication, the rights indication storing an indication of the rights of the first user to the initial model data corresponding to the initial 3D model; and

wherein the first association between the first watermark and the initial model data is based on the rights indication.

3. The method of claim 2, wherein:

the rights indication is a first rights indication and the request is a first request; and

the method further comprises;

receiving a second request from the second user to secure rights to the updated 3D model, and in response to the second request, generating a second rights indication, the second rights indication storing an indication of rights of the second user to a portion of the updated model data corresponding to the modified respective portion of the initial model data; and

generating and storing the second association is based on the second rights indication.

receive a user-initiated command from a second user to modify a portion of the initial 3D model;

apply a change, in accordance with the user-initiated command, to the initial model data to form updated model data corresponding to an updated 3D model;

store an indication of a second association between the second user and the change;

cause a rendering, on a display device, of a first watermark and a second watermark in conjunction with a rendering of the updated 3D model, wherein the first watermark corresponds to the first association and is indicative of rights of the first user to the initial model data and the second watermark corresponds to the second association and is indicative of rights of the second user to the updated model data; and

prevent the second user from disassociating the first watermark and the updated 3D model.

11. A system according to claim 10, wherein the rendering of the first watermark is in a background of a display including the rendering of the updated 3D model.

12. A system according to claim 10, wherein the first watermark includes user-indicated content.

13. A system according to claim 10, wherein the indication of the first association is included in first metadata corresponding to the initial 3D model, and wherein the indication of the second association is included in second metadata corresponding to the change.

14. A system according to claim 10, wherein the indication of the first association and the indication of the second association are included in metadata corresponding to the updated 3D model.

15. A system according to claim 10, wherein the first memory storing the initial model data is accessed by the second user via a web browser.

16. A system according to claim 10, wherein:

the second user is accorded a set of access privileges to the initial 3D model; and

the system further comprises additional computer-executable instructions to accord, to a third user, a different set of access privileges to the initial 3D model.

17. A system according to claim 16, wherein the different set of access privileges includes permission, for the third user, to at least one of:

view the initial 3D model, add a new portion to the initial 3D model, delete a selected portion of the initial 3D model, export the initial 3D model, or copy the initial 3D model.

18. A non-transitory, tangible computer-readable medium comprising:

computer-executable instructions stored thereon and executable to;
