Dieses Snippet enthält eine Klasse namens DXObject, welche ein mit DirectX zu zeichnendes Objekt definiert, bestehend aus:
Mesh Model : Das DirectX-Mesh
Vector3 Position : Die Position des Objekts
Material MeshMaterial : Das Material des Objekts
Außerdem eine Klasse namens DirectXForm, die von System.Windows.Forms.Form erbt und DirectX implementiert. Sie besitzt folgende öffentliche Member:
Device D3DDevice : Das DirectX-Device
event Rendered : Wird ausgelöst, wenn eine Szene gerendert wurde
List<DXObject> Meshes : Die zu zeichnende Liste von DXObjects
Vector3 CameraPosition : Die Position der Kamera
Vector3 LookAtPoint : Der Look-At-Vektor
Microsoft.DirectX.DirectInput.Device DXKeyboard : Die Tastatur
Color BackgroundColor : Die Hintergrundfarbe
Anderen Änderungen lassen sich direkt am Device D3DDevice ändern.
Nötig sind folgende Assemblyverweise (alle aus dem DirectX-SDK):
Microsoft.DirectX,
Microsoft.DirectX.Direct3DX,
Microsoft.DirectX.DirectInput
und folgende Using-Direktiven:
using System;
using System.Collections.Generic;
using System.Drawing;
using System.Windows.Forms;
using Microsoft.DirectX;
using Microsoft.DirectX.Direct3D;
using Microsoft.DirectX.DirectInput;
Verwendet wird es wie eine normale Form.
Dieses Snippet soll jediglich die Verwendung von DirectX vereinfachen!
Hier möchte ich auf das C#-DirectX Tutorial auf
http://www.riemers.net/eng/Tutorials/dxcsharp.php
verweisen, welches mir das nötige Wissen verschafft hat, ohne welches ich dieses Snippet nicht hätte schreiben können.
