Detection of partially obscured objects in three dimensional stereoscopic scenes
System and methods for user interface elements for use within a 3D scene. The 3D scene may be presented by at least one display, which includes displaying at least one stereoscopic image of the 3D scene by the display(s). The 3D scene may be presented according to a first viewpoint. One or more user interface elements may be used. The 3D scene may be updated in response to the use of the user interface elements.
1. A method comprising:

determining a location and orientation in physical space of an input device, wherein the location and orientation in physical space maps to a corresponding position and orientation within the 3D stereoscopic scene;
determining an intersection of a depicted beam within the 3D stereoscopic scene with an obscured portion of the second object, wherein the depicted beam extends from the corresponding position and orientation within the 3D stereoscopic scene; and
displaying first and second portions of the depicted beam with different representations to indicate the intersection, wherein the first portion extends from the corresponding position and orientation towards the intersection, and wherein the second portion extends away from the intersection.
2. The method of claim 1 , further comprising:
displaying the depicted beam with the first representation prior to said determining the intersection.
3. The method of claim 1 ,
wherein the first representation comprises one or more of:
a first line style; or
a first line color; and
wherein the second representation comprises one or more of:
a second line style; or
a second line color.
4. The method of claim 1 , further comprising:
rendering the first object transparent or translucent; and
displaying the partially obscured portion of the second object from the first viewpoint.
5. The method of claim 1 , further comprising:
determining a region of the first object that corresponds to the obscured portion of the second object;
rendering the region of the first object transparent; and
displaying the obscured portion of the second object from the first viewpoint.
6. The method of claim 1 , further comprising:
determining a region of the first object that corresponds to the obscured portion of the second object;
rendering the region of the first object translucent; and
displaying the obscured portion of the second object from the first viewpoint.
7. A non-transitory computer accessible memory medium storing program instructions for utilizing an input device with a three-dimensional (3D) stereoscopic scene, wherein the program instructions are executable by a processor to:
display a three dimensional (3D) stereoscopic scene according to a first viewpoint, wherein the 3D stereoscopic scene comprises a rendering of at least a first object and a second object from the first viewpoint, wherein the rendering of the first object at least partially obscures a portion of the rendering of the second object;
determine a location and orientation in physical space of an input device, wherein the location and orientation in physical space maps to a corresponding position and orientation within the 3D stereoscopic scene;
determine an intersection of a depicted beam within the 3D stereoscopic scene with an obscured portion of the second object, wherein the depicted beam extends from the corresponding position and orientation within the 3D stereoscopic scene; and
display first and second portions of the depicted beam with different representations to indicate the intersection, wherein the first portion extends from the corresponding position and orientation towards the intersection, and wherein the second portion extends away from the intersection.
8. The non-transitory computer accessible memory medium of claim 7 ,
wherein the program instructions are further executable to display the depicted beam with the first representation prior to said determining the intersection.
9. The non-transitory computer accessible memory medium of claim 7 ,
wherein the first representation comprises one or more of:
a first line style; or
a first line color; and
wherein the second representation comprises one or more of:
a second line style; or
a second line color.
10. The non-transitory computer accessible memory medium of claim 7 ,
wherein the program instructions are further executable to:
render the first object transparent or translucent; and
display the partially obscured portion of the second object from the first viewpoint.
11. The non-transitory computer accessible memory medium of claim 7 ,
wherein the program instructions are further executable to:
determine a region of the first object that corresponds to the obscured portion of the second object;
render the region of the first object transparent; and
display the obscured portion of the second object from the first viewpoint.
12. The non-transitory computer accessible memory medium of claim 7 ,
wherein the program instructions are further executable to:
determine a region of the first object that corresponds to the obscured portion of the second object;
render the region of the first object translucent; and
display the obscured portion of the second object from the first viewpoint.
13. The non-transitory computer accessible memory medium of claim 7 ,
wherein the depicted beam comprises a rendering of a continuous beam.
14. A system for utilizing an input device with a three-dimensional (3D) stereoscopic scene, the system comprising:
a memory; and
a processor in communication with the memory, wherein the processor is configured to:
display a three dimensional (3D) stereoscopic scene according to a first viewpoint, wherein the 3D stereoscopic scene comprises a rendering of at least a first object and a second object from the first viewpoint, wherein the rendering of the first object at least partially obscures a portion of the rendering of the second object;
determine a location and orientation in physical space of an input device, wherein the location and orientation in physical space maps to a corresponding position and orientation within the 3D stereoscopic scene;
determine an intersection of a depicted beam within the 3D stereoscopic scene with an obscured portion of the second object, wherein the depicted beam extends from the corresponding position and orientation within the 3D stereoscopic scene; and
display first and second portions of the depicted beam with different representations to indicate the intersection, wherein the first portion extends from the corresponding position and orientation towards the intersection, and wherein the second portion extends away from the intersection.
15. The system of claim 14 ,
wherein the processor is further configured to display the depicted beam with the first representation prior to said determining the intersection.
16. The system of claim 14 ,
