Practical 2:
AIM: Code for diffuse lightening 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
