GLUT Libraries can be downladed at: The process for installing GLUT is pretty much the same.

So I did what anyone would do, build my own 3D CAD software (beware Autodesk).

Some of the (few) features: 1) The big viewport offers a perspective view your 3D realm 2) The bottom two viewports offer front and side view 3) you can undo any mistakes (sort of) 4) the object can be scaled in all the x, y and z coordinates independently or all at the same 5) You can take a screen shot of your masterpiece As you can see this is a very basic and limited application, in this application I will be explaining my process of building the application and how I used OpenGL to achieve this.

About this instructable: The goal of this instructable is to introduce beginners to the exciting world of Computer Graphics and OpenGL.

This instructable is written to provide the quick and simple to follow steps I used to create a very basic CAD application.

I have used no OOPs concepts and I have tried to keep programming as basic as possible, but basic knowledge of C is required.

My methodology for writing the code is not recommended, instead, I have included hyperlinks at the bottom of each step which will take you to the official OpenGL websites and show the proper way to use the functions.

I had made a personal goal to finish this application in a week, so there still a lot of bugs in the build, but I will be improving my code whenever I get the time to do so.

And of course, I am not responsible for any damage caused by my code to your computer.

If you find any shortcomings or errors in the code, please reply in the comments and I will fix it.

The main Libraries I used to make this application: 1) SDL (main lib to make the application) 2) SOIL ( to import aand use images in my application easier) 3) GLUT ( only some utilities to make life easier ) Q: Why SDL I thought we were going to use OpenGL.

A: OpenGL is simply a cross-platform standard and API for 2D3D rendering on the computers monitor.On the other hand SDL is a cross-platform library to provide low level access to Audio, keyboard etc and other peripherals via OpenGL.

In other words, it is there to make life easier for us while programming OpenGL apps.

Downloading SDL: 1) Go to and download SDL2-devel-2.0.3-VC.zip Visual C Development Libraries as shown in (Image 1).

Adding to Visual Studio: 1) Create a new project (Image 2) 2) go to InstalledOther LanguagesVisual CWin32, Name your project and hit Ok (Image 3) 3) A new window will open after some loading, hit Next 4) In the next window, uncheck Security Development Lifecycle (SDL) checks and check Empty Project button, and hit Finish (Image 4) 5) When the project is created, go to Solution Explorer Right click on your project name Select Properties (Image 5).

VC Directories Click on Include Directories and a.

If you see any errors, ignore them (Image 8).

Now go to the root directory of your project file, this is usually in the Documents folder, and go to the Debug folder C:UsersArsh pcDocumentsVisual Studio 2013 Debug In this folder, add the SDL2.dll file which should be in the library directory of your SDL download (libx86SDL2.dll) folder.

Now after all this is done, we can install SOIL.

What is SOIL it is a library with which we can easily load image files into our projects.

To get SOIL, head over to The installation process is the same as it was for SDL, Set the Include directories path to src folder in the SOIL download file, Set the Libraries Directories path to lib folder.

Now in the lib folder, you might notice there is a single file named libSOIL.a, now this cannot be processed by visual studio, it must be converted to a SOIL.lib for proper functioning.

To do this go to projects VC Double click SOIL.vcproj file, open it with visual studio, Execute the code, and you should get a SDL.lib in projects VC Debug folder.

I used SDL for the most of the part, but to make things easier I also used some GLUT utilities.
