Thread: opening window using glut

i figure this is about as simple as it gets...

Code:

#include <windows.h>
#include <gl/glut.h>

GLvoid Render(GLvoid)
{
	glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
                // do your drawing here
}

GLvoid Initialize(GLvoid)
{
	glClearColor(0.0f,0.0f,0.0f,1.0f);
	glClearDepth(1.0f);
                // do your initializing here
}

GLvoid Resize(GLint Width,GLint Height)
{
	if (Height == 0)
	{
		Height = 1;
	}
	
	glViewport(0,0,Width,Height);
	glMatrixMode(GL_PROJECTION);
	glLoadIdentity();
		
	gluPerspective(45,(float)Width/(float)Height,1.0f,100.0f);
		
	glMatrixMode(GL_MODELVIEW);
	glLoadIdentity();
}

main()
{
	glutInitDisplayMode(GLUT_DOUBLE | GLUT_RGBA);
	glutCreateWindow("OpenGL");
	glutDisplayFunc(Render);
	glutReshapeFunc(Resize);

	Initialize();

	glutMainLoop();
	return 0;
}
