Detailed Description

Class Point3, Class Quat.

Description:

A ScaleValue describes an arbitrary non-uniform scaling in an arbitrary axis system. The Point3 s gives the scaling along the x, y, and z axes, and the quaternion q defines the axis system in which scaling is to be applied. All methods are implemented by the system.

Data Members:

Point3 s;

Scale components.

Quat q;

The axis system of application.

Constructor & Destructor Documentation

ScaleValue() [1/3]

ScaleValue ( )

inline

Remarks

Constructor. s and q have their own initializers.

{ }

ScaleValue() [2/3]

ScaleValue ( const Point3 &  as )

inline

Remarks

Constructor. The scale data member is initialized to as. The quaternion data member is set to the identity.

{ s = as; q = IdentQuat(); }

ScaleValue() [3/3]

ScaleValue ( const Point3 &  as, const Quat &  aq  )

inline

Remarks

Constructor. The scale data member is initialized to as. The quaternion data member is set to aq.

Operators:

{s = as; q = aq; }

Member Function Documentation

operator+=()

ScaleValue& operator+= ( const ScaleValue &  value )

inline

Remarks

Adds a ScaleValue to this ScaleValue.

      { (*this)=(*this)+value; return (*this);}

operator*=()

ScaleValue& operator*= ( const float  value )

inline

Remarks

Multiplies this ScaleValue by a float. This updates the scale components.

      { (*this)=(*this)*value; return (*this);}

operator=()

ScaleValue& operator= ( const ScaleValue &  v )

inline

{s=v.s;q=v.q; return (*this);}

operator[]()

float& operator[] ( int  el )

inline

Remarks

Array access operator. This allows the scale components to be accessed using the array operator.

Parameters:

int el

Specifies the element to access: 0=x, 1=y, 2=z.

{return s[el];}

operator==()

int operator== ( const ScaleValue &  sv ) const

inline

Remarks

Equality operator. Test for equality between two ScaleValue's.

Returns

Nonzero if the ScaleValue's are equal; otherwise 0.

                                              {
       return ((sv.s == s) && (sv.q == q));
   }

operator!=()

int operator!= ( const ScaleValue &  sv ) const

inline

                                              {
       return ((sv.s != s) || (sv.q != q));
   }

Equals()

int Equals ( const ScaleValue &  sv, float  epsilon = 1E-6f  ) const

inline

                                                                 {
       return sv.s.Equals(s, epsilon) && sv.q.Equals(q, epsilon);
   }
