Abstract: A computer-generated virtual light source manipulator having one or more affordances for manipulating a computer-generated virtual light sources is disclosed. Selection of a virtual light source can cause a light source manipulator tailored for that virtual light source to be displayed over the virtual light source. The light source manipulator can include various lines, circles and the like that can define starting boundaries (e.g., surfaces that represent the start location and initial aperture of light emission from the virtual light source), ending boundaries (e.g., surfaces that represent the extent or reach (i.e., end location or projection distance) and final aperture of light transmission from the virtual light source), and fade boundaries (e.g., surfaces that represent the beginning of the fading of the virtual light source). The light source manipulators can also include one or more disc or spherical affordances for adjusting these boundaries.
