Ejemplos
En el siguiente ejemplo de código se crea un dispositivo.
Public Class Form1
Inherits Form
' Set global variables for this project.
Private device As Device = Nothing
Public Sub New()
' Set the initial size and caption of the form.
Me.ClientSize = New System.Drawing.Size(400, 300)
Me.Text = "D3D Tutorial 01: CreateDevice"
End Sub 'New
Public Function InitializeGraphics() As Boolean
Try
' Set up presentation parameters and create the Direct3D
' device.
Dim presentParams As New PresentParameters()
presentParams.Windowed = True
presentParams.SwapEffect = SwapEffect.Discard
device = New Device(0, DeviceType.Default, Me, CreateFlags.None, presentParams)
Return True
Catch
Return False
End Try
End Function
Private Sub Render()
If device Is Nothing Then
Return
End If
'Clear the backbuffer to a blue color.
device.Clear(ClearFlags.Target, System.Drawing.Color.Blue, 1.0F, 0)
'Begin the scene.
device.BeginScene()
'Render scene objects, if desired.
'End the scene.
device.EndScene()
device.Present()
End Sub
Protected Overrides Sub OnPaint(ByVal e As System.Windows.Forms.PaintEventArgs)
' Render on painting.

End Sub

If Fix(System.Convert.ToByte(e.KeyChar)) = Fix(System.Windows.Forms.Keys.Escape) Then
' Handle the ESC key being pressed.
Me.Close()
End If
End Sub
Shared Sub Main()
Dim DeviceForm As New Form1()
Try
If Not DeviceForm.InitializeGraphics() Then

MsgBox("Could not initialize Direct3D. This tutorial will exit.")
Return
End If
DeviceForm.Show()
'While the form is still valid, render and process messages.
'While DeviceForm.Created
' DeviceForm.Render()

'End While
Finally
DeviceForm.Dispose()
