Practical 5:
Aim: Code for Texturing the Rectangle 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 WindowsFormsApplication4

    {
        private Microsoft.DirectX.Direct3D.Device device;
        private CustomVertex.PositionTextured[] v = new CustomVertex.PositionTextured[6];
        private Texture texture;
        public Form2()
        {
            InitializeComponent();
        }

        private void Form2_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));

            v[0] = new CustomVertex.PositionTextured(new Vector3(0, 2, 1), 0, 0);
            v[1] = new CustomVertex.PositionTextured(new Vector3(0, -2, 1), 0, 1);
            v[2] = new CustomVertex.PositionTextured(new Vector3(2, -2, 1),-1,1);
            v[3] = new CustomVertex.PositionTextured(new Vector3(2, -2, 1), -0, 0);
            v[4] = new CustomVertex.PositionTextured(new Vector3(2, 2, 1), 0, 1);
            v[5] = new CustomVertex.PositionTextured(new Vector3(0, 2, 1), -1, 1);
            texture = new Texture(device, new Bitmap("D:\\design\\p3.jpg"), 0, Pool.Managed);
        }

        private void Form2_Paint(object sender, PaintEventArgs e)
        {
            device.Clear(ClearFlags.Target, Color.BlueViolet, 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();

        }
    }
