Detailed Description

class HPlane

The HPlane class is the data type of a plane.

The HPlane class encapsulates the a, b, c and d parameters of the plane equation.

Subclassed by HPlaneKey

Public Functions

inline HPlane(float const A = 0, float const B = 1, float const C = 0, float const D = 0)

inline HPlane(HVector const &normal, float const D)

inline HPlane(HPlane const &p)

inline void Set(float A, float B, float C, float D)

This method sets an HPlane object with parameter values.

inline double ClassifyPoint(HPoint const &p) const

This method determines if given point is infront of or behind the plane.

Returns:A positive value if the point is in front of the plane or a negative value if the point is behind the plane. If the value is 0, the point is on the plane.

inline void CalculateNormal(HPoint &normal) const

This method returns a perpendicular plane vector.

Parameters:normal – Pass by reference. The method returns the value for a normalized vector that is perpendicular to the plane.

inline bool Equal(HPlane const *p, float epsi1 = (1e-5f), float epsi2 = (1e-5f)) const

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