A portable, open-source, coherent noise-generating library for C++
Main Page | Modules | Class Hierarchy | Class List | File List | Class Members # 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.
