Detailed Description

Definition at line 8 of file Matrix4.h.

Constructor & Destructor Documentation

Matrix4() [1/3]

Matrix4 ( )

inline

Default constructor.

Note

It does NOT initialize the matrix for efficiency.

Definition at line 21 of file Matrix4.h.

Matrix4() [2/3]

Matrix4 ( double  m00, double  m01, double  m02, double  m03, double  m10, double  m11, double  m12, double  m13, double  m20, double  m21, double  m22, double  m23, double  m30, double  m31, double  m32, double  m33  )

inline

Definition at line 25 of file Matrix4.h.

Matrix4() [3/3]

Matrix4 ( double *  mat )

inline

Definition at line 49 of file Matrix4.h.

Member Function Documentation

concatenate()

Matrix4 concatenate ( const Matrix4 &  m2 ) const

inline

Definition at line 101 of file Matrix4.h.

convert()

void convert ( double  mat[16] )

inline

Definition at line 69 of file Matrix4.h.

makeTrans()

void makeTrans ( double  tx, double  ty, double  tz  )

inline

Definition at line 248 of file Matrix4.h.

operator!=()

bool operator!= ( const Matrix4 &  m2 ) const

inline

Tests 2 matrices for inequality.

Definition at line 229 of file Matrix4.h.

operator*() [1/3]

Matrix4 operator* ( const Matrix4 &  m2 ) const

inline

Matrix concatenation using '*'.

Definition at line 129 of file Matrix4.h.

operator*() [2/3]

Vector3d operator* ( const Vector3d &  v ) const

inline

Vector transformation using '*'.

Remarks

Transforms the given 3-D vector by the matrix, projecting the result back into w = 1.

Note

This means that the initial w is considered to be 1.0, and then all the tree elements of the resulting 3-D vector are divided by the resulting w.

Definition at line 143 of file Matrix4.h.

operator*() [3/3]

Matrix4 operator* ( double  scalar ) const

inline

Definition at line 259 of file Matrix4.h.

operator+()

Matrix4 operator+ ( const Matrix4 &  m2 ) const

inline

Matrix addition.

Definition at line 159 of file Matrix4.h.

operator-()

Matrix4 operator- ( const Matrix4 &  m2 ) const

inline

Matrix subtraction.

Definition at line 188 of file Matrix4.h.

operator==()

bool operator== ( const Matrix4 &  m2 ) const

inline

Tests 2 matrices for equality.
