使用例

ColorValueFixed 構造体を使用する方法を次のコード例に示します。

Visual Basic

' This code example is taken from the
' Managed Direct3D Mobile Fixed-Point Lighting Sample
' of the .NET Compact Framework Samples in the
' .NET Framework SDK.

' Set light #0 to be a simple, faint grey directional light so
' the walls and floor are slightly different shades of grey
device.LightsFixed(0).Type = LightType.Directional
device.LightsFixed(0).Direction = New Vector3Fixed(0.3F, -0.5F,
 0.2F)
device.LightsFixed(0).Update()
' Set light #1 to be a simple, bright directional light to use
' on the mesh representing light #2
device.LightsFixed(1).Type = LightType.Directional
device.LightsFixed(1).Direction = New Vector3Fixed(0.5F, -0.5F,
 0.5F)
device.LightsFixed(1).DiffuseColor = ColorValueFixed.FromColor(System.Drawing.Color.Blue)
device.LightsFixed(1).Update()

' Light #2 will be the light used to light the floor and
' walls.  It will be set up in FrameMove() since it changes
' every frame.
