void	Normalize () Normalizes the plane equation so that 'norm' is a unit vector.
inline void	Set (float a, float b, float c, float d) Set the value of the four plane components.

csVector3 norm

The normal vector (or the (A,B,C) components).

float DD

The D component of the plane.

csPlane()

Initialize to the xy plane.

csPlane(const csVector3& plane_norm, float d=0)

Initialize the plane.

csPlane(float a, float b, float c, float d=0)

Initialize the plane.

inline csVector3& Normal()

Return the normal vector of this plane.

inline float& A()

Return the A component of this plane.

inline float& B()

Return the B component of this plane.

inline float& C()

Return the C component of this plane.

inline float& D()

Return the D component of this plane.

inline void Set(float a, float b, float c, float d)

Set the value of the four plane components.

inline float Classify(const csVector3& pt)

Classify the given vector with regards to this plane.

static float Classify(float A, float B, float C, float D, const csVector3& pt)

Classify a vector with regards to four plane components.

inline float Distance(const csVector3& pt)

Compute the distance from the given vector to this plane. This function assumes that 'norm' is a unit vector. If not, the function returns distance times the magnitude of 'norm'.

void Invert()

Reverses the direction of the plane while maintianing the plane itself.

void Normalize()

Normalizes the plane equation so that 'norm' is a unit vector.
