minCameraOrbit property
Set the minimum orbital values of the camera. Note "Infinity" is not an accepted keyword, but the default can still be obtained by passing "auto". The radius value for "auto" is a conservative value to ensure the camera never enters the model, so be careful when setting this to another value.
