MatrixFixed Structure

Represents a matrix for fixed-point math operations.

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

public struct MatrixFixed

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.

The following examples shows how to use a MatrixFixed structure.

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);

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
