Sphere properties
Spheres created at runtime aren’t saved with the cast member’s media when the Director movie is
saved. Their
type is #sphere. Their surface is generated by sweeping a two-dimensional
semicircle arc in the xy plane from
startAngle to endAngle in the y-axis. If startAngle = 0.0
and endAngle= 360.0, a full sphere is generated. If startAngle = 180.0 and endAngle = 360.0,
a half sphere is generated. These properties can be modified or animated at runtime.
Cylinder properties
Cylinders have a
type property of #cylinder. Director generates a cylinder’s surface by sweeping
a 2D line around the z-axis in the xy plane from
startAngle to endAngle. If startAngle = 0.0
and endAngle = 360.0, a full cylinder is generated. If startAngle = 180.0 and endAngle =
360.0
, a half cylinder is generated. These properties can be modified or animated at runtime.
Property Access Description Value Range
radius Get and set Radius of the sphere. Positive floating-point
value. The default is
25.0.
resolution Get and set Controls the number of polygons used in the
creation of the sphere surface. The higher the
value, the smoother the surface.
An integer value of 1 or
greater. The default is 20.
startAngle Get and set Starting angle of the sweep. Floating-point value of
from 0.0 to 360.0. The
default is 0.0.
endAngle Get and set Ending angle of the sweep. Floating-point value of
from 0.0 to 360.0. The
default is 360.0.
Property Access Description Value Range
topRadius Get and set Radius of the top of the cylinder. Setting this
value to 0 produces a cone.
Positive floating-point
value. The default
is 25.0.
bottomRadius Get and set Radius of the bottom of the cylinder. Positive floating-point
value. The default
is 25.0.
numSegments Get and set Number of polygonal segments from bottom
to top.
An integer value greater
than 0.
resolution Get and set Number of polygonal segments around the
circumference of the circle. Controls the
smoothness of the cylinder’s appearance.
An integer value greater
than 1.
height Get and set Height of the cylinder along the z-axis. Positive floating-point
value. The default
is 50.0.
topCap Get and set Value indicating whether the top of the cylinder
is closed or open.
TRUE = closed.
TRUE or FALSE. The
default is
TRUE.
bottomCap Get and set Value indicating whether the bottom of the
cylinder is closed or open.
TRUE =closed.
TRUE or FALSE. The
default is
TRUE.
