Detailed Description

4x4 Matrix Class

This runs at F32 precision.

Constructor & Destructor Documentation

MatrixF ( bool identity = false )

inlineexplicit

Create an uninitialized matrix.

Parameters

identity If true, initialize to the identity matrix.

MatrixF ( const EulerF & e )

inlineexplicit

Create a matrix to rotate about origin by e.

See Also: set

MatrixF	(	const EulerF &	e,
		const Point3F &	p
	)

inline

Create a matrix to rotate about p by e.

See Also: set

Member Function Documentation

MatrixF & affineInverse ( )

inline

Take inverse without disturbing position data.

Ie, take inverse of 3x3 submatrix.

void dumpMatrix ( const char * caption = NULL ) const

bool fullInverse ( )

Compute the inverse of the matrix.

Computes inverse of full 4x4 matrix. Returns false and performs no inverse if the determinant is 0.

Note: In most cases you want to use the normal inverse function. This method should be used if the matrix has something other than (0,0,0,1) in the bottom row.

void getColumn	(	S32	col,
		Point4F *	cptr
	)		const

inline

Copy the requested column into a Point4F.

void getColumn	(	S32	col,
		Point3F *	cptr
	)		const

inline

Copy the requested column into a Point3F.

This drops the bottom-most row.

Point3F getPosition ( ) const

inline

Get the position of the matrix.

This is the 4th column of the matrix.

void getRow	(	S32	row,
		Point4F *	cptr
	)		const

inline

Copy the specified row into a Point4F.

void getRow	(	S32	row,
		Point3F *	cptr
	)		const

inline

Copy the specified row into a Point3F.

Right-most item is dropped.

MatrixF & identity ( )

inline

Make this an identity matrix.

static U32 idx	(	U32	i,
		U32	j
	)

inlinestatic

Get the index in m to element in column i, row j

This is necessary as we have m as a one dimensional array.

Parameters

i	Column desired.
j	Row desired.

MatrixF & inverse ( )

inline

Invert m.

bool isAffine ( ) const

Check to see if this is an affine matrix.

bool isIdentity ( ) const

inline

Checks for identity matrix.

MatrixF & mul ( const MatrixF & a )

inline

M * a -> M.

MatrixF & mul	(	const MatrixF &	a,
		const MatrixF &	b
	)

inline

a * b -> M

MatrixF & mul ( const F32 a )

inline

M * a -> M.

MatrixF & mul	(	const MatrixF &	a,
		const F32	b
	)

inline

a * b -> M

void mul ( Point4F & p ) const

inline

M * p -> p (full [4x4] * [1x4])

void mul ( Box3F & b ) const

inline

Axial box -> Axial Box.

void mulP ( Point3F & p ) const

inline

M * p -> p (assume w = 1.0f)

void mulP	(	const Point3F &	p,
		Point3F *	d
	)		const

inline

M * p -> d (assume w = 1.0f)

void mulV ( VectorF & p ) const

inline

M * v -> v (assume w = 0.0f)

void mulV	(	const VectorF &	p,
		Point3F *	d
	)		const

inline

M * v -> d (assume w = 0.0f)

void normalize ( )

inline

Normalize the matrix.

operator F32 * ( )

inline

Allow people to get at m.

operator F32 * ( ) const

inline

Allow people to get at m.

F32& operator()	(	S32	row,
		S32	col
	)

inline

Convenience function to allow people to treat this like an array.

MatrixF & scale ( const Point3F & p )

inline

M * Matrix(p) -> M.

MatrixF & set ( const EulerF & e )

inline

Initialize matrix to rotate about origin by e.

MatrixF & set	(	const EulerF &	e,
		const Point3F &	p
	)

inline

Initialize matrix to rotate about p by e.

void setColumn	(	S32	col,

MatrixF & setCrossProduct ( const Point3F & p )

inline

Initialize matrix with a cross product of p.

void setPosition ( const Point3F & pos )

inline

		const Point4F &	cptr
	)

inline

Set the specified row from a Point4F.

void setRow	(	S32	row,
		const Point3F &	cptr
	)
