Getting started with using OpenGL / freeglut in a Microsoft Visual Studio environment for 32 bit versions.

1. Obtain freeglut

Go to the freeglut site to obtain the MSVC package:

http://www.transmissionzero.co.uk/software/freeglut-devel/

At the time of writing this demonstration we obtain version 3.0.0 in zip file format: http://files.transmissionzero.co.uk/software/development/GLUT/freeglut-MSVC.zip

2. Obtain glew

http://sourceforge.net/projects/glew/files/glew/

At the time of writing this demonstration we obtain version 1.13.10 in zip file format: http://sourceforge.net/projects/glew/files/latest/download?source=files

3. Place freeglut and glew in the location of your choice:

4. Create a new empty project in Visual Studio

Add your main.cpp source code file. Don’t have to put anything in it for the time being:

5. Set the Additional Include Directories

Select project properties > C/C++ > General tab > Additional Include Directories.

Do this for the freeglut and glew packages:

6. Set the Additional Library Directories

Select project properties > Linker > General > Additional Library Directories.

Again, do this for the freeglut and glew packages:

7. Place the freeglut dll in your project location.

freeglut.dll is found in the \bin folder:

Take a copy of the dll and paste it into your project location (where main.cpp is located):

8. Try with a simple example

#include <GL\glew.h>
#include <GL\freeglut.h>

void Display() 
{
	glClear(GL_COLOR_BUFFER_BIT);
    glBegin(GL_POLYGON);
    glVertex2f(0.0, 0.0);                    
    glVertex2f(0.5, 0.0);                    
    glVertex2f(0.5, 0.5);                    
    glVertex2f(0.0, 0.5);                    
    glEnd();
    glFlush();
}

int main(int argc, char** argv) 
{
    glutInit(&argc, argv);
    glutInitDisplayMode(GLUT_SINGLE);
    glutInitWindowSize(300, 300);                    // window size
    glutInitWindowPosition(500, 500);                // distance from the top-left screen
    glutCreateWindow("BadproG - Hello world :D");    // message displayed on top bar window
    glutDisplayFunc(Display);
    glutMainLoop();
    return 0;
}

Build and run the project to give you the following result:

Try it out and see. Feel free to contact me if you have any problems and or want to give feedback.
