Practical 3:
AIM: Draw a Traingle using direct 3D 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
    {
        Microsoft.DirectX.Direct3D.Device device;
        public Form1()
        {
            InitializeComponent();
            InitDevice();
        }
        private void InitDevice()
        {
            PresentParameters pp = new PresentParameters(); pp.Windowed = true;
            pp.SwapEffect = SwapEffect.Discard;
            device = new Device(0, DeviceType.Hardware, this, CreateFlags.HardwareVertexProcessing, pp);
        }


   private void Render()
        {
            CustomVertex.TransformedColored[] vertexes = new CustomVertex.TransformedColored[3];
            vertexes[0].Position = new Vector4(240, 110, 0, 1.0f); vertexes[0].Color = System.Drawing.Color.FromArgb(0, 255, 0).ToArgb();


            vertexes[1].Position = new Vector4(380, 420, 0, 1.0f); vertexes[1].Color = System.Drawing.Color.FromArgb(0, 0, 255).ToArgb(); vertexes[2].Position = new Vector4(110, 420, 0, 1.0f);
            device.Clear(ClearFlags.Target, Color.DarkOrchid, 1.0f, 0); device.BeginScene();
            device.VertexFormat = CustomVertex.TransformedColored.Format; device.DrawUserPrimitives(PrimitiveType.TriangleList, 1, vertexes); device.EndScene();
            device.Present();
        }



        private void Form1_Paint(object sender, PaintEventArgs e)
        {
            Render();
        }

        private void Form1_Load(object sender, EventArgs e)
        {

        }
    }
