Abstract

A light source within a real world scene can be identified. The light source can be associated with a one or more attributes. The light source can emit light to illuminate the real world scene. The attributes can include intensity, wavelength, and/or orientation. A live view of the real world scene can be presented within an interface of a computing device. The attributes associated with the light source can be determined. A light map for the light source within the real world scene can be computed. The light map can be a graphical visualization of an approximation of a propagation of light emanating from the light source within the scene.

Claims

1. A method for visualizing light maps comprising:

identifying at least one light source within a real world scene, wherein the light source is associated with a plurality of attributes, wherein the light source emits light to illuminate the real world scene, wherein the attributes comprise of at least one of a light source intensity, a light source wavelength, and orientation;

presenting a live view of the real world scene within an interface of a computing device;

determining at least one of the plurality of attributes associated with the light source;

computing a light map for the light source within the real world scene, wherein the light map is a graphical visualization of an approximation of a propagation of light emanating from the at least one light source within the scene;

computing a boundary for a visualization for the light source, wherein the visualization, referred to as a light source visualization, is a visibly bounded graphic of a shape appearing as an overlay on a view of the real-world scene, wherein the graphic explicitly demarcates a bound region indicative of a bound region that is illuminated by the light source; and

visually presenting within the interface the light source visualization for the light map, wherein the light source visualization overlays a view also presented within the interface of the real world scene.

2. The method of claim 1, further comprising:

presenting the visualization of the light source within the interface when the at least one light source is absent from the scene or is not emitting light.

3. The method of claim 1, further comprising:

establishing editing handles for the light source visualization, which permits a user to interactively change the bound region of the light source visualization; and

visually presenting the light source visualization with the editing handles.

4. The method of claim 1, further comprising:

receiving a touch screen gesture as user input to select the visualization within the interface of the computing device;

determining a user established change to the bound region and a corresponding change to an intensity of the light source; and

performing the change to the light source resulting in at least one of the orientation and the intensity of the light source is modified based on the user established change.

5. The method of claim 1, wherein the computing device is at least one of a point and shoot camera and a digital SLR camera.

6. The method of claim 1, further comprising:

determining an object within the real world scene affected by the light emanating from the light source; and

automatically adjusting a view of the illumination of the object based on the propagation and diffusion of light on the object.

7. The method of claim 1, wherein the light source is at least one of a hot light and a strobe.

8. The method of claim 1, wherein the view is presented within an augmented reality computing device.

9. The method of claim 1, further comprising:

establishing a text tag for the light source visualization; and

visually presenting the tag within the interface.

computing a boundary for a visualization for the light source, wherein the visualization, referred to as a light source visualization, is a visibly bounded graphic of a shape appearing as an overlay on a view of the real-world scene, wherein the graphic explicitly demarcates a bound region indicative of a bound region that is illuminated by the light source;

graphically rendering the light source visualization, wherein the light source visualization is a graphical representation of an approximation of a propagation of light emanating from of the at least one light source; and

presenting the real world scene and the visualization within a display of the computing device, wherein the light source visualization overlays a view presented view of the real world scene.

12. The method of claim 11, wherein the attributes is at least one of an intensity, a duration, a color, and a direction.

13. The method of claim 11, further comprising:

responsive to the rendering, adjusting a view of the real world scene to approximate the presence of light from the light source associated with the visualization; and

presenting the view of the real world scene within the display of the computing device.

14. The method of claim 11, further comprising:

presenting the visualization of the light source within the interface when the at least one light source is absent from the scene or is not emitting light.
