Examples

// Multiplies a Vector3D by a Matrix3D using the static Multiply method.  
// Returns a Vector3D.

Vector3D vector1 = new Vector3D(20, 30, 40);
Matrix3D matrix1 = new Matrix3D(10, 10, 10, 0, 20, 20, 20, 0, 30, 30, 30, 0, 5, 10, 15, 1);
Vector3D vectorResult = new Vector3D();

vectorResult = Vector3D.Multiply(vector1,matrix1);
// vector Result is equal to (2000, 2000, 2000)

' Multiplies a Vector3D by a Matrix3D using the static Multiply method.  
' Returns a Vector3D.

Dim vector1 As New Vector3D(20, 30, 40)
Dim matrix1 As New Matrix3D(10, 10, 10, 0, 20, 20, 20, 0, 30, 30, 30, 0, 5, 10, 15, 1)
Dim vectorResult As New Vector3D()

vectorResult = Vector3D.Multiply(vector1,matrix1)
' vector Result is equal to (2000, 2000, 2000)

Remarks

Matrix3D has the following row-vector syntax:


M11	M12	M13	M14
M21	M22	M23	M24
M31	M32	M33	M34
OffsetX	OffsetY	OffsetZ	M44

Note that because the fourth column is also accessible, the matrix allows developers to represent affine as well as non-affine transforms.

Matrices can be appended or prepended to other matrices. Appending matrix A to matrix B denotes a transformation by B and then by A:
