Detailed Description
The QSphereGeometry class is most commonly used internally by the QSphereMesh but can also be used in custom Qt3DRender::QGeometryRenderer subclasses.

normalAttribute : Qt3DRender::QAttribute* const
Holds the geometry normal attribute.
Access functions:
| Qt3DRender::QAttribute * | normalAttribute() const |
positionAttribute : Qt3DRender::QAttribute* const
Holds the geometry position attribute.
Access functions:

radius : float
Holds the radius of the sphere.
Access functions:
| float | radius() const |
| void | setRadius(float radius) |
Notifier signal:
| void | radiusChanged(float radius) |
rings : int
Holds the number of rings in the sphere.
Access functions:
| int | rings() const |
| void | setRings(int rings) |
Notifier signal:

tangentAttribute : Qt3DRender::QAttribute* const
Holds the geometry tangent attribute.
Access functions:
| Qt3DRender::QAttribute * | tangentAttribute() const |
texCoordAttribute : Qt3DRender::QAttribute* const
Holds the geometry texture coordinate attribute.
Access functions:
| Qt3DRender::QAttribute * | texCoordAttribute() const |
