Flipping stereoscopic radiographs

A computer-readable medium comprising:

• a computer program product having computer-readable code embodied therein for manipulating a stereoscopic radiograph comprised of first and second images generated by a radiographic system, wherein the first and second images include images of physical pointers, the computer program product comprising:
• a module for defining a first screen parallax for the stereoscopic radiograph, the first screen parallax defining a first 3-Dimensional (3-D) perspective of the stereoscopic radiograph;
• a module for flipping the first and second images about a vertical axis to produce a second stereoscopic radiograph having a second screen parallax, the second screen parallax defining a second 3-D perspective of the second stereoscopic radiograph;
• and
• a module for modifying the second screen parallax to produce a third 3-D perspective of the second stereoscopic radiograph and to place selected ones of the pointers at a predetermined depth in the third 3-D perspective of the stereoscopic radiograph.

A graphics engine for manipulating a stereoscopic radiograph comprised of first and second images generated by a radiographic system, wherein the first and second images include images of physical pointers, the graphics engine comprising:

• a module for defining a first screen parallax for the stereoscopic radiograph, the first screen parallax defining a first 3-Dimensional (3-D) perspective of the stereoscopic radiograph;
• a module for flipping the first and second images about a vertical axis to produce a second stereoscopic radiograph having a second screen parallax, the second screen parallax defining a second 3-D perspective of the second stereoscopic radiograph;
• and
• a module for modifying the second screen parallax to produce a third 3-D perspective of the second stereoscopic radiograph and to place selected ones of the physical pointers at a predetermined depth in the third 3-D perspective of the stereoscopic radiograph.
