The BCC Comet filter creates an auto-animated comet that streaks across
the screen. The comet is compromised of particles whose sizes, shapes, and
colors can be adjusted. You can also set the length and speed of the effect,
adjust the camera perspective, position the starting and ending points of the
comet, and apply a gravitational force to adjust the comet’s movement.
When you play the effect, the comet’s position automatically animates from the
source point to the destination point.
