FixedPoint Structure
Visual Studio 2008
Represents a 16.16 fixed-point number.
Assembly: Microsoft.WindowsMobile.DirectX (in Microsoft.WindowsMobile.DirectX.dll)
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 Dim i As Integer For i = 0 To numberTrees - 1 Dim t As New Tree() ' Position the trees randomly Do Dim fTheta As Single = 2.0F * _ System.Convert.ToSingle(Math.PI) * _ System.Convert.ToSingle(randObj.NextDouble()) Dim fRadius As Single = 25.0F + 55.0F * _ System.Convert.ToSingle(randObj.NextDouble()) Dim position As Vector3Fixed position.X = CType(fRadius * _ System.Convert.ToSingle( _ Math.Sin(fTheta)), FixedPoint) position.Z = CType(fRadius * _ System.Convert.ToSingle(Math.Cos(fTheta)), FixedPoint) position.Y = CType(HeightField( _ System.Convert.ToSingle(position.X), _ System.Convert.ToSingle(position.Z)), FixedPoint) t.Position = position Loop While Not IsTreePositionValid(t.Position)
