init(radius:)
Creates a sphere geometry with the specified radius.
Declaration
convenience init(radius: CGFloat)Parameters
- radius:
The radius of the sphere in its local coordinate space.
Return Value
A new sphere geometry.
Discussion
The sphere is centered in its local coordinate system. For example, if you create a sphere whose radius is 5.0, it extends from -5.0 to 5.0 along each of the the x, y, and z-axes.
