Get the vertices of the Sphere primitive, and control their position

Hello dear friends!
Can you please tell me if I can get the vertices of the "Sphere" primitive and control their position in space? If this is possible, how?

```
private void LoadSphere()
{
Sphere sphere = new Sphere(); // this sphere needs to control the position of individual vertices or quads
sphere.QuadricDrawStyle = DrawStyle.Line;
sphere.Transformation.ScaleX = 4f;
sphere.Transformation.ScaleY = 4f;
sphere.Transformation.ScaleZ = 6f;
sphere.AddEffect(arcBallEffect);
//int stacks = sphere.Stacks;
//sphere.Material = aMaterial;
sceneControl.Scene.SceneContainer.AddChild(sphere);
}
```
