FixedPoint Structure

Represents a 16.16 fixed-point number.

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

public struct FixedPoint : IComparable, IFormattable, IConvertible
public final class FixedPoint extends ValueType implements IComparable, IFormattable, 
	IConvertible
JScript suports the use of structures, but not the declaration of new ones.

This structure is used to interoperate with the various types in Windows Mobile Direct 3D that have fixed-point interfaces. The internal representation of this class is an Int32 structure.

The following example shows how you can use a FixedPoint structure.

// The following code is from the
// Direct3D Mobile Fixed Point Billboard Sample.
// It uses FixedPoint to position meshes of trees randomly.

        // Initialize the tree data
        for (int i=0; i<numberTrees; i++)
        {
            Tree t = new Tree();


do
{
    float fTheta  = 2.0f * (float)Math.PI *
        (float)rand.NextDouble();
    float fRadius = 25.0f + 55.0f * (float)rand.NextDouble();
    Vector3Fixed position;
    position.X  =
        (FixedPoint)(fRadius * (float)Math.Sin(fTheta));
    position.Z  =
        (FixedPoint)(fRadius * (float)Math.Cos(fTheta));
    position.Y  =
        (FixedPoint)HeightField((float)position.X,
        (float)position.Z);
    t.Position = position;
}
while (!IsTreePositionValid(t.Position));

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