Background
Background allows you to specify a set of smoothly graded colors for both the ground and
sky colors in your scene. The sky forms a sphere around your scene. This sphere has horizontal gradation
of colors, which gradually ranges from SkyHoriz to SkyZenith.
Similarly, the ground forms a hemisphere under your scene, with the
infinite radius but down as though inside the sky sphere.
Properties:
GroundHoriz
the ground color close to horizon.
GroundNadir
the Nadir (straight down) ground color.
SkyHoriz
the sky color close to horizon.
SkyZenith
the Zenith sky color.
Events:
Bind
the background is visible or not in the scene when
the incoming event is TRUE or FALSE.
GroundHoriz
the incoming event of the SFFloat type specifies the
ground color close to horizon. Repeats an incoming event as an outgoing one.
GroundNadir
the incoming event of the SFFloat type specifies the Nadir
(straight down) ground color. Repeats an incoming event as an outgoing one.
SkyHoriz
the incoming event of the SFFloat type specifies the sky color
close to horizon. Repeats an incoming event as an outgoing one.
SkyZenith
the incoming event of the SFFloat type specifies the Zenith sky color.
Repeats an incoming event as an outgoing one.
