MatrixFixed Structure

Represents a matrix for fixed-point math operations.

Namespace: Microsoft.WindowsMobile.DirectX.Direct3D
Assembly: Microsoft.WindowsMobile.DirectX (in microsoft.windowsmobile.directx.dll)

Syntax

'Declaration
Public Structure MatrixFixed
'Usage
Dim instance As MatrixFixed
public struct MatrixFixed
public value class MatrixFixed
public final class MatrixFixed extends ValueType
Not applicable.

Remarks

This structure represents a 4x4 matrix of FixedPoint values. The fields of this structure are named with the row number first, then the column number.

In Microsoft Windows Mobile Direct3D, the M34 element of a projection matrix cannot be a negative number. If an application needs to use a negative value in this location, it should scale the entire projection matrix by -1 instead.

Example

The following examples shows how to use a MatrixFixed structure.

Sub DoDraw() 
    Dim matrWorld As MatrixFixed
    Dim matrfxRotate As MatrixFixed = MatrixFixed.Identity
    matrWorld = MatrixFixed.Multiply(matrfxRotate, New MatrixFixed(Matrix.RotationZ(System.Convert.ToSingle(Math.PI * 2.0))))
    device.SetTransformFixed(TransformType.World, matrWorld)
    Me.Refresh()
End Sub
void DoDraw()
{
    MatrixFixed matrWorld;
    MatrixFixed matrfxRotate = MatrixFixed.Identity;
    matrWorld = (MatrixFixed.Multiply(matrfxRotate, new MatrixFixed(Matrix.RotationZ((float)(Math.PI * 2.0)))));
    device.SetTransformFixed(TransformType.World, matrWorld);
    this.Refresh();
}
