Sphere properties

Spheres created at run time 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 run time.

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.
