Creates rotation matrix by rotation around axis.

Parameters:

	a	Angle (in radians) of rotation around axis X.
	b	Angle (in radians) of rotation around axis Y.
	c	Angle (in radians) of rotation around axis Z.

template<class T>

Note:

Test of equality is based of threshold EPSILON value. To be two values equal, must satisfy this condition all elements of matrix | lws[i] - rhs[i] | < EPSILON, same for y-coordinate, z-coordinate, and w-coordinate.

const [inline]

Inequality test operator

Parameters:

rhs

Right hand side argument of binary operator.

Returns:

not (lhs == rhs) :-P

template<class T>

T& Matrix4< T >::at	(	int	x,
		int	y
	)			[inline]

Get reference to element at postion (x,y).

Parameters:

	x	Number of column (0..3)
	y	Number of row (0..3)

template<class T>

const T& Matrix4< T >::at	(	int	x,
		int	y
	)			const [inline]

Get constant reference to element at postion (x,y).

Parameters:

	x	Number of column (0..3)
	y	Number of row (0..3)
