	r	A System.Int32 specifying the matrix row count.

Derm.Render.Matrix.Matrix	(	Matrix	m,
		int	c,
		int	r
	)

Complement matrix constructor.

Parameters:

Member Function Documentation

virtual object Derm.Render.Matrix.Clone

(

)

[virtual]

Clone this Matrix.

Returns:

It returns a deep copy of this Matrix.

Reimplemented in Derm.Render.Matrix4x4, Derm.Render.ModelMatrix, and Derm.Render.ProjectionMatrix.

virtual float Derm.Render.Matrix.GetDeterminant

(

)

[virtual]

SquareMatrix determinant.

The function is virtual to provide a way to optimize this function. Optimization are possible when the size of the square matrix is known. It's possible to implement ASM code using MMX and SSE instructions to speed up the implementation, when the matrix extents are known.

virtual Matrix4x4 Derm.Render.Matrix.GetInverseMatrix

(

)

[virtual]

Inverse SquareMatrix of this SquareMatrix.

Returns:

A SquareMatrix representing the inverse matrix of this SquareMatrix. of this

Exceptions:

System.Exception

In the case the SquareMatrix in singular an exception is thrown.

static Derm.Render.Matrix.operator float[]

(

Matrix

a

)

[explicit, static]

Convert a Matrix to an array of float.

Parameters:

a

A Matrix to be convertex.

Returns:

It returns an array of System.Float represeting the matrix a .

static Matrix Derm.Render.Matrix.operator*	(	Matrix	m1,
		Matrix	m2
	)			[static]

Multiply two Matrix.

Parameters:

	m1	A Matrix specifying the left multiplication operand.
	m2	A Matrix specifying the right multiplication operand.

Returns:

A Matrix resulting from the product of the matrix m1 and the matrix m2 .

static Matrix Derm.Render.Matrix.operator*	(	Matrix	m,
		float	scalar
	)			[static]

Multiply a matrix with a scalar value.

Parameters:

	m	A Matrix
	scalar	A System.Single

Returns:

A Matrix

static Matrix Derm.Render.Matrix.operator+	(	Matrix	m1,
		Matrix	m2
	)			[static]

Sum two Matrix.

Parameters:

	m1	A Matrix specifying the left Matrix.
