Point — simulates a spotlight type of lighting effect that radiates light evenly
in all directions.
Bar — simulates lighting from a bar-shaped long, thin lighting source.
Plane — simulates a parallel light striking the entire surface of the video.
Position
Used with Point and Bar light sources to control the position of the point
light, or the position of some point along the bar light, with respect to the
X, Y and Z axes in 3D space.
Rotation
Used with Bar and Plane light sources to control the direction of the bar light,
or the direction that the plane light faces along the X, Y and Z axes. Setting
Rotation to 0 places the Plane light directly behind the viewer’s head.
Appearance
Light Intensity — Changes the incident value of the light (which may appear
as a change to the reflectivity of the surface).
Light Softness — Control of softness of the edge of the light. 100% creates
maximum softness, 0% gives a hard edge. At extremely small values some
aliasing artifacts may appear.
Surface Gloss — Provides soft knob control of how much light is scattered as
it is reflected off the surface of the picture. At 100% the lighting acts like it
is reflecting off of a mirror. At 0% the light acts like it is reflecting off of a
frosted piece of glass.
Flare
When light reflects off a surface two lighting components result, the
primary reflected light and a glare (flared halo) of scattered light. The Flare
controls provide soft knobs to adjust this lighting component.
Flare Intensity — Controls the amount of the flare light scattered off the sur-
face.
Flare Ratio — Controls the ratio between the primary light and the flare light.
100% is all primary light, 0% all flare light.
Independent Flare Intensity
This button allows independent control of the primary and flare compo-
nents of the light. When Off, changing the value of one control will alter the
appearance of the other component of the light. The actual values reported
