Silverlight 3D 开发全解析：从基础渲染到多对象创建

1. 3D 立方体基础渲染

在 3D 场景中，我们首先要创建一个立方体。以下是创建投影矩阵和设置效果的代码：

Dim projection As Matrix = _
    Matrix.CreatePerspectiveFieldOfView(MathHelper.PiOver4, 1.33, 1, 100)

' Set up the effect.
effect = New BasicEffect(device)
effect.World = Matrix.Identity
effect.View = view
effect.Projection = view * projection
effect.VertexColorEnabled = True

渲染代码如下：

Private Sub drawingSurface_Draw(ByVal sender As Object, ByVal e As DrawEventArgs)
    Dim device As GraphicsDevice = GraphicsDeviceManager.Current.GraphicsDevice
    device.Clear(New Color(0, 0, 0))
    device.SetVertexBuffer(vertexBuffer)

    For Each pass As EffectPass In effect.CurrentTechnique.Pass
