	noise::module::Exponent Class Reference [Modifier Modules] #include <exponent.h> Inheritance diagram for noise::module::Exponent: List of all members. Detailed Description Noise module that maps the output value from a source module onto an exponential curve. Because most noise modules will output values that range from -1.0 to +1.0, this noise module first normalizes this output value (the range becomes 0.0 to 1.0), maps that value onto an exponential curve, then rescales that value back to the original range. This noise module requires one source module. Public Member Functions   Exponent ()   Constructor. double  GetExponent () const   Returns the exponent value to apply to the output value from the source module. virtual int  GetSourceModuleCount () const   Returns the number of source modules required by this noise module. virtual double  GetValue (double x, double y, double z) const   Generates an output value given the coordinates of the specified input value. void  SetExponent (double exponent)   Sets the exponent value to apply to the output value from the source module. Protected Attributes double  m_exponent   Exponent to apply to the output value from the source module. Constructor & Destructor Documentation Exponent::Exponent (   )    Constructor. The default exponent is set to noise::module::DEFAULT_EXPONENT. Member Function Documentation double noise::module::Exponent::GetExponent (   )  const [inline]   Returns the exponent value to apply to the output value from the source module. Returns: The exponent value. Because most noise modules will output values that range from -1.0 to +1.0, this noise module first normalizes this output value (the range becomes 0.0 to 1.0), maps that value onto an exponential curve, then rescales that value back to the original range. virtual int noise::module::Exponent::GetSourceModuleCount (   )  const [inline, virtual]   Returns the number of source modules required by this noise module. Returns: The number of source modules required by this noise module. Implements noise::module::Module. double Exponent::GetValue (  double  x, double  y, double  z )  const [virtual]   Generates an output value given the coordinates of the specified input value. Parameters: x  The x coordinate of the input value. y  The y coordinate of the input value. z  The z coordinate of the input value. Returns: The output value. Precondition: All source modules required by this noise module have been passed to the SetSourceModule() method. Before an application can call this method, it must first connect all required source modules via the SetSourceModule() method. If these source modules are not connected to this noise module, this method raises a debug assertion. To determine the number of source modules required by this noise module, call the GetSourceModuleCount() method. Implements noise::module::Module. void noise::module::Exponent::SetExponent (  double  exponent  )  [inline]   Sets the exponent value to apply to the output value from the source module. Parameters: exponent  The exponent value. Because most noise modules will output values that range from -1.0 to +1.0, this noise module first normalizes this output value (the range becomes 0.0 to 1.0), maps that value onto an exponential curve, then rescales that value back to the original range.
