Method and system for transparency adjustment and occlusion resolution for urban landscape visualization
View Patent ↗According to certain embodiments of the present invention, a graphical presentation is generated from a data representation. A transparency lens is applied to reveal a region-of-interest within an original image. The region-of-interest is occluded by an occluding portion of the original image. The transparency lens includes a focal region having a transparency to reduce occlusion of the region-of-interest by the occluding portion. The transparency lens also includes a shoulder region between the focal region and a foreground of the original image. The shoulder region has decreasing transparency from the focal region to the foreground. In an embodiment, occluding portion is sliced into slices normal to a depth axis of the original image. Transparencies are applied to the slices as a function of depth of the slices to form the shoulder region.
1. A method for generating a graphical presentation from a data representation, the method comprising:
applying a transparency lens to reveal a region-of-interest within an original image, wherein the region-of-interest is occluded by an occluding portion of the original image;
wherein the transparency lens includes:
a focal region having a transparency to reduce occlusion of the region-of-interest by the occluding portion, and
a shoulder region between the focal region and a foreground of the original image, wherein the shoulder region has decreasing transparency as depth decreases from the focal region to the foreground.
2. The method of claim 1 , further comprising slicing the occluding portion into slices normal to a depth axis of the original image; and
applying transparencies to the slices as a function of depth of the slices to form the shoulder region.
3. The method of claim 2 , wherein the occluding portion comprises an occluding polygon.
4. The method of claim 3 , further comprising converting the original image into a mesh of polygons including the occluding polygon.
5. The method of claim 1 , wherein the original image comprises a landscape image;
wherein the occluding portion comprises a first building; and
wherein the region-of-interest comprises a second building.
6. The method of claim 1 , wherein the original image comprises a computer-aided design (“CAD”) image;
wherein the occluding portion comprises a first component; and
wherein the region-of-interest comprises a second component.
7. The method of claim 1 , further comprising adjusting the transparency of the focal region through a graphical user interface (“GUI”).
8. The method of claim 7 , further comprising adjusting the transparency of the shoulder region through the GUI.
9. The method of claim 1 , further comprising adjusting an extent of the focal region through a GUI.
10. The method of claim 1 , wherein the focal region further includes a magnification; and
wherein at least a portion of the shoulder region has a magnification that is less than the magnification of the focal region and greater than a magnification of the foreground.
11. At least one non-transitory computer-readable medium including program instructions, the program instructions comprising:
lens application instructions for applying a transparency lens to reveal a region-of-interest within an original image, wherein the region-of-interest is occluded by an occluding portion of the original image;
wherein the transparency lens includes:
a focal region having a transparency to reduce occlusion of the region-of-interest by the occluding portion, and
a shoulder region between the focal region and a foreground of the original image, wherein the shoulder region has decreasing transparency as depth decreases from the focal region to the foreground.
12. The program instructions of claim 11 , further comprising slicing instructions for slicing the occluding portion into slices normal to a depth axis of the original image; and
applying transparencies to the slices as a function of depth of the slices to form the shoulder region.
13. The program instructions of claim 12 , wherein the occluding portion comprises an occluding polygon.
14. The program instructions of claim 13 , further comprising conversion instructions for converting the original image into a mesh of polygons including the occluding polygon.
15. The program instructions of claim 11 , wherein the original image comprises a landscape image;
wherein the occluding portion comprises a first building; and
wherein the region-of-interest comprises a second building.
16. The program instructions of claim 11 , wherein the original image comprises a computer-aided design (“CAD”) image;
wherein the occluding portion comprises a first component; and
wherein the region-of-interest comprises a second component.
17. The program instructions of claim 11 , further comprising adjustment instructions for adjusting the transparency of the focal region through a graphical user interface (“GUI”).
18. The program instructions of claim 17 , further comprising adjustment instructions for adjusting the transparency of the shoulder region through the GUI.
19. The program instructions of claim 11 , further comprising adjustment instructions for adjusting an extent of the focal region through a GUI.
20. The program instructions of claim 11 , wherein the focal region further includes a magnification; and
wherein at least a portion of the shoulder region has a magnification that is less than the magnification of the focal region and greater than a magnification of the foreground.
