Detailed Method Descriptions:

Construct a 4x4 identity matrix.

void vtkMatrix4x4 ()

Construct a 4x4 matrix with the values which are contained in the argument m.

void vtkMatrix4x4 (const vtkMatrix4x4 &)

Set the elements of the matrix to the same values as the elements of the source Matrix.

void DeepCopy (vtkMatrix4x4 *)

Set all of the elements to zero.

void Zero ()

Matrix Inversion (adapted from Richard Carling in "Graphics Gems," Academic Press, 1990).

	void Invert (vtkMatrix4x4 * ,vtkMatrix4x4 *)
	void Invert ()

Transpose the matrix and put it into out.

	void Transpose (vtkMatrix4x4 * ,vtkMatrix4x4 *)
	void Transpose ()

Multiply this matrix by a point (in homogeneous coordinates). and return the result in result. The in[4] and result[4] arrays must both be allocated but they can be the same array.

void MultiplyPoint (float ,float )

Multiply a point (in homogeneous coordinates) by this matrix, and return the result in result. The in[4] and result[4] arrays must both be allocated, but they can be the same array.

void PointMultiply (float ,float )

Compute adjoint of the matrix and put it into out.

void Adjoint (vtkMatrix4x4 * ,vtkMatrix4x4 *)

Compute the determinant of the matrix and return it.

float Determinant (vtkMatrix4x4 *)

Sets the element i,j in the matrix.

void SetElement (int ,int ,float )

Returns the element i,j from the matrix.

float GetElement (int ,int )
