## Detailed Description

class `HFrExtent` : public HConstFRSimpType

  HFrExtent is a simplification type that tweaks the maximum extent suboption in Set_Heuristics. The maximum extent value is calculated based on the current simplification level and a multiplier.

  Public Functions

  inline `HFrExtent`()

    The default constructor.

  inline `HFrExtent`(int min, int max)

    The constructor that allows you the set the minimum and maximum simplification levels.

    Parameters: | min – The minimum simplification level. max – The maximum simplification level.

  inline virtual `~HFrExtent`()
  inline void `SetMultiplier`(int mp)

    This method sets the multiplier. The multiplier is use to set the maximum extent for the culling option of ::Set_Heuristics. When the Set method is called, the maximum extent option will be set with a value calculated from the simplication level and the multiplier.

    Parameters: | mp – The multiplier used in the calculation to set the maximum extent.

  virtual void `Set`(HConstantFrameRate *pCfr, int SimpLevel)

    Set rendering options based on simplification type.

    Parameters: | pCfr – A pointer to a HConstantFrameRate Object. SimpLevel – Simplification level for the current type

  inline void `SetUseLod`(bool ul)

    This methods enables/disables the use of LOD options for rendering.

    Parameters: | ul – Pass true if you want to set the LOD options to be set to %15 and 0% for threshold and the fallback to be set to coarsest. Pass false if you don’t want to use set any LOD options.

  inline bool `GetUseLod`() const
  inline virtual ConstFRType `GetType`()

    Returns: | The simplification type associated with this class.

  Public Static Functions

  static inline HConstFRSimpType *`Create`(int min, int max)

    Create a new simplification type object. Avoids object ownership problems.

    Parameters: | min – lowest simplification level max – highest simplification level
