List of all members.

Public Member Functions
	Matrix ()
	Default constructor. The matrix is initialized to identity.
	Matrix (float s)
	Constructor initializing all elements to the given value.
virtual	~Matrix ()
	Destructor. Does nothing.
Matrix &	operator= (float s)
	Assignment from a scalar value.
float	operator() (int i, int j) const
	Returns a copy of the element at position row,column (i,j).
float &	operator() (int i, int j)
	Returns a reference to the element at position row,column (i,j).
Matrix &	zero ()
	Clear all elements to zero.
Matrix &	identity ()
	Set matrix to identity.
Matrix &	scale (float sx, float sy, float sz)
	Setup scaling matrix.
Matrix &	translation (float tx, float ty, float tz)
	Setup translation matrix.
Matrix &	rotX (float rx)
	Setup rotation matrix around the x-axis, where the rotation angle is given in degrees.
Matrix &	rotY (float ry)
	Setup rotation matrix around the y-axis, where the rotation angle is given in degrees.
Matrix &	rotZ (float rz)
	Setup rotation matrix around the z-axis, where the rotation angle is given in degrees.
Matrix	operator+ (const Matrix &m) const
	Addition of two matrices.
Matrix &	operator+= (const Matrix &m)
	Addition of two matrices in place.
Matrix	operator- (const Matrix &m) const
	Subtraction of two matrices.
Matrix &	operator-= (const Matrix &m)
	Subtraction of two matrices in place.
Matrix	operator * (float s) const
	Multiplication of matrix by scalar.
Matrix &	operator *= (float s)
	Multiplication by scalar in place.
Point	operator * (const Point &p) const
	Matrix/point multiplication. The point is translated by the last column.
Vector	operator * (const Vector &v) const
	Matrix/vector multiplication. The vector is not translated by the last column.
Matrix	operator * (const Matrix &m) const
	Matrix multiplication.
Matrix &	operator *= (const Matrix &m)
	Matrix multiplication in place.
float	determinant () const
	Compute the determinant of the matrix.
Matrix	inverse () const
	Compute the inverse of the matrix.
Protected Attributes
float	e [16]
	The matrix elements.
Friends
Matrix	operator * (float s, const Matrix &m)
	Multiplication of sclar by matrix.
std::ostream &	operator<< (std::ostream &os, const Matrix &A)
	Write matrix elements to an output stream.
