	noise::model::Sphere Class Reference [Models] #include <sphere.h> List of all members. Detailed Description Model that defines the surface of a sphere. This model returns an output value from a noise module given the coordinates of an input value located on the surface of a sphere. To generate an output value, pass the (latitude, longitude) coordinates of an input value to the GetValue() method. This model is useful for creating: seamless textures that can be mapped onto a sphere terrain height maps for entire planets This sphere has a radius of 1.0 unit and its center is located at the origin. Public Member Functions   Sphere ()   Constructor.   Sphere (const module::Module &module)   Constructor. const module::Module &  GetModule () const   Returns the noise module that is used to generate the output values. double  GetValue (double lat, double lon) const   Returns the output value from the noise module given the (latitude, longitude) coordinates of the specified input value located on the surface of the sphere. void  SetModule (const module::Module &module)   Sets the noise module that is used to generate the output values. Constructor & Destructor Documentation Sphere::Sphere (  const module::Module &  module  )    Constructor. Parameters: module  The noise module that is used to generate the output values. Member Function Documentation const module::Module& noise::model::Sphere::GetModule (   )  const [inline]   Returns the noise module that is used to generate the output values. Returns: A reference to the noise module. Precondition: A noise module was passed to the SetModule() method. double Sphere::GetValue (  double  lat, double  lon )  const   Returns the output value from the noise module given the (latitude, longitude) coordinates of the specified input value located on the surface of the sphere. Parameters: lat  The latitude of the input value, in degrees. lon  The longitude of the input value, in degrees. Returns: The output value from the noise module. Precondition: A noise module was passed to the SetModule() method. This output value is generated by the noise module passed to the SetModule() method. Use a negative latitude if the input value is located on the southern hemisphere. Use a negative longitude if the input value is located on the western hemisphere. void noise::model::Sphere::SetModule (  const module::Module &  module  )  [inline]   Sets the noise module that is used to generate the output values. Parameters: module  The noise module that is used to generate the output values. This noise module must exist for the lifetime of this object, until you pass a new noise module to this method.
