First hand-on OpenGL with Visual C++ Posted by Unknown , Thursday, September 20, 2012 at 11:42 PM, in

First we have setup OpenGL in Windows:
2 steps below need to be taken care of:

Step 1:

Step 2:

Open Visual Studio 2008:

File -> New Project -> Visual C++ -> General -> Empty Project

Right Click on Source Files -> New Item... -> C++ file (.cpp)

Write code below:

[Code]

#include "stdafx.h"
#include // this include also gl.h and glu.h

void init(void)
{
    glClearColor(1.0 , 1.0 ,1.0 , 0.0); // Set display-window color to white

    glMatrixMode(GL_PROJECTION); // Set projection parameter
    gluOrtho2D(0.0,200.0,0.0,150.0); // 

}

void lineSegment(void){
    glClear(GL_COLOR_BUFFER_BIT); // Clear display window.

    glColor3f(1.0, 0.0, 0.0); // Set line segment color to red (R,G,B)
    glBegin(GL_LINES);
        glVertex2i(180,15); // Specify line-segment geometry x1,y1 ; x2,y2
        glVertex2i(10,145);
    glEnd();

    glFlush(); // Profess all OpenGL routines as quickly as possible.
}

void main(int argc, char** argv)
{
    glutInit(&argc, argv); // Initialize GLUT dll that we copy it in c:\windows\System32
    glutInitDisplayMode (GLUT_SINGLE | GLUT_RGB); // set display mode
    glutInitWindowPosition (50,100);  // set top-left display window position
    glutInitWindowSize(400,300); // set display window width / height
    glutCreateWindow("An Example OpenGL Program"); // Create display window title.

    init(); // Execute initialization procedure
    glutDisplayFunc(lineSegment); //  Send graphics to display window. our function above main
    glutMainLoop(); // Display everything and wait.
}

[/Code]

Run it:
Output:

Congratulation you have run your first C++ OpenGL.
Vic,

Correction for the header files I have made a mistake while commenting and accidentally delete the Glut header file declaration you would find the correction below:

#include "stdafx.h"
#include "GL/glut.h"// this include also gl.h and glu.h
