Getting Started with OpenGL GLUT

Since GLUT is platform independent the natural language to choose is ANSI C, and for Windows of course, Pelles C. In this tutorial I will show you how to set up Pelles C for programming in GLUT and also show some sample code.

Before you begin you will need the GLUT header and library files, glut32.lib, glut.lib and glut.h. I have a download available here that my code samples are tested with:
http://www.trajectorylabs.com/OpenGL/GLUT.ZIP These files are from the OpenGL SuperBible book 3rd Edition CD. The very latest Win32 GLUT files can be found here: http://www.xmission.com/~nate/glut.html My code however is not guaranteed to work with anything other than the files I have supplied.

Once you have downloaded the header and library files add them to the proper Pelles C directories as shown:
PellesC\Lib\Win\glut32.lib
PellesC\Lib\Win\glut.lib
PellesC\Include\Win\gl\glut.h

Now fire up Pelles C and start a new Win32 program (EXE) as a new workspace. Select File - New - Source code and paste the code below.

int main (int argc, char **argv)
{
glutInit(&argc, argv);
glutInitDisplayMode(GLUT_DOUBLE | GLUT_RGB);
glutInitWindowSize(250, 250);
glutInitWindowPosition(100, 100);
glutCreateWindow("My First OpenGL Application");
init();
glutDisplayFunc(display);
glutMainLoop();
return 0;
}

void init(void)
{
glClearColor(0.0, 0.0, 0.0, 0.0);
glColor3f(0.0, 0.0, 1.0);
glMatrixMode(GL_PROJECTION);
glLoadIdentity();
glOrtho(-10.0, 10.0, -10.0, 10.0, -10.0, 10.0);
}
