## Detailed Description

class `HPoint`

  The HPoint class is the data type of a three-dimensional point.

  The HPoint class encapsulates the x, y, and z coordinates of a 3-dimensional point. HPoint simplifies the passing of 3-dimensional point data to all of the MVO and derived classes. It is widely used by public and internal functions as well as by native HOOPS routines.

  Public Functions

  inline `HPoint`()

    The default constructor.

  inline `HPoint`(float X, float Y, float Z = 0.0f)

    This constructor accepts floats for the x, y and z coordinates.

  inline `HPoint`(HPoint const *p)

    This constructor accepts a pointer to an HPoint object.

  inline `HPoint`(HPoint const &p)

    This constructor accepts an HPoint reference.

  inline void `Set`(float X, float Y, float Z = 0.0f)

    This method packs an HPoint object with coordinate values.

  inline void `Set`(HPoint *p)

    This method packs an HPoint object with coordinate values from a given HPoint.

  inline void `Set`(HPoint const *p)

    This method packs an HPoint object with coordinate values from a given HPoint.

  inline void `Set`(HPoint &p)

    This method packs an HPoint object with coordinate values from a given HPoint that is passed by reference.

  inline void `Set`(HPoint const &p)

    This method packs an HPoint object with coordinate values from a given HPoint that is passed by reference.

  inline void `Add`(float X, float Y, float Z = 0.0)

    This method increases/decreases the coordinate values of an existing HPoint object.

    Parameters: | X – The amount in which you want to increment or decrement the x coordinate. Y – The amount in which you want to increment or decrement the y coordinate. Z – The amount in which you want to increment or decrement the z coordinate.

  inline HPoint const `operator+`(HPoint const &p2) const
  inline HPoint const `operator*`(float const rhs) const
  inline HPoint const `operator/`(float const rhs) const
  inline HPoint const &`operator+=`(HPoint const &rhs)
  inline HPoint const &`operator-=`(HPoint const &rhs)
  inline HPoint const &`operator*=`(float const rhs)
  inline HPoint const &`operator/=`(float const rhs)
  inline bool `operator==`(HPoint const &rhs) const
  inline bool `operator!=`(HPoint const &rhs) const
  HPoint &`operator=`(HPoint const&) = default
  inline bool `Equal`(HPoint const *p, float epsi = (1e-5f)) const

    This method checks if the xyz components of the point are equal.

  inline bool `Equal`(HPoint const &p, float epsi = (1e-5f)) const

    This method checks if the xyz components of the point are equal.
