Practical 4:
AIM: Code for Texturing the Traingle using Direct3D 11.
Step 1:Create new project, and select “Windows Forms Application”, select .NET Framework as 2.0 in Visuals C#.Right Click on properties Click on open click on build Select Platform Target and Select x86.
Step 2:Click on View Code of Form 1.
Step 3:Go to Solution Explorer, right click on project name, and select Add Reference. Click on Browse and select the given .dll files which are “Microsoft.DirectX”, “Microsoft.DirectX.Direct3D”, and “Microsoft.DirectX.DirectX3DX”.
Step 4:Go to Properties Section of Form, select Paint in the Event List and enter as Form1_Paint.
Step 5:Copy and Paste the below given code into Form’s C# code file. Namespace must be as same as your project name.
Program:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using Microsoft.DirectX;
using Microsoft.DirectX.Direct3D;


namespace WindowsFormsApplication1
{
    public partial class Form1 : Form
    {
        private Microsoft.DirectX.Direct3D.Device device;
        private CustomVertex.PositionTextured[] v = new CustomVertex.PositionTextured[3];
        private Texture texture;



        public Form1()
        {
            InitializeComponent();
        }
        private void Form1_Paint(object sender, PaintEventArgs e)
        {
            device.Clear(ClearFlags.Target, Color.DarkRed, 1, 0);
            device.BeginScene();
            device.SetTexture(0, texture);
            device.VertexFormat = CustomVertex.PositionTextured.Format;
            device.DrawUserPrimitives(PrimitiveType.TriangleList, v.Length / 3, v);
            device.EndScene();
            device.Present();

        }

        private void Form1_Load(object sender, EventArgs e)
        {
             PresentParameters obj = new PresentParameters();
            obj.Windowed = true;
            obj.SwapEffect = SwapEffect.Discard;
            device = new Device(0, DeviceType.Hardware, this, CreateFlags.HardwareVertexProcessing, obj);
            device.Transform.Projection = Matrix.PerspectiveFovLH(3.14f / 4, device.Viewport.Width / device.Viewport.Height, 1f, 1000f);
            device.Transform.View = Matrix.LookAtLH(new Vector3(0, 0, 20), new Vector3(0,0,10), new Vector3(0, 1, 2));
            device.RenderState.Lighting = false;
            v[0] = new CustomVertex.PositionTextured(new Vector3(0, 0, 0), 0, 0);
            v[1] = new CustomVertex.PositionTextured(new Vector3(5, 0, 0), 0, 1);
            v[2] = new CustomVertex.PositionTextured(new Vector3(0, 5, 0), -1, 1);
            texture = new Texture(device, new Bitmap("C:\\Users\\SDV\\Pictures\\sunset.jpg"), 0, Pool.Managed);
        }

        }
