I was recently helping a friend get set up running OpenGL and I realized that most of the instructions available online for this are fairly outdated. So, here’s a quick run through to set the record straight. This guide is meant for beginners who just want to get a simple OpenGL desktop app going on a Windows machine.
This guide assume you have the following installed:
1. Windows 7 or 8
2. Visual Studio 2008, 2010, or 2012
By convention, we assume the OS is installed to the C drive and VS is installed to a folder such as “C:\Program Files (x86)\Microsoft Visual Studio 10.0″ (for 2010, 2008 maps to 9.0 and 2012 to 11.0).
The first step is to download GLUT (the OpenGl Utility Toolkit). This library provides a slew of helper functions for working with OpenGL, including setting up a window. Grab the latest binaries from here. Unzip this and copy the binaries out into the following directories. Be aware that these are 32-bit binaries. You will need to create the “gl” folder in “\Microsoft Visual Studio 10.0\VC\include\”, as it doesn’t already exist.
| File | Location |
| glut32.dll | C:\Windows\SysWOW64\ |
| glut.h | C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\include\gl\ |
| glut32.lib | C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\lib\ |
| Windows 64-bit |
| File | Location |
| glut32.dll | C:\Windows\System32\ |
| glut.h | C:\Program Files\Microsoft Visual Studio 10.0\VC\include\gl\ |
| glut32.lib | C:\Program Files\Microsoft Visual Studio 10.0\VC\lib\ |
| Windows 32-bit |
Now boot up Visual Studio. You’ll want to create a simple Win32 console application. In VS 2010, open the New Project dialog and look at the list of templates. Select Visual C++\Win32\Win32 Console Application. Click through the Wizard that appears, leaving the defaults in place.
At this point you should get a solution with a couple of default files and a “_tmain” entry function. Right-click the project you created, go to Properties, then open Configuration Properties\Linker\Advanced
Choose the NO.
Close the settings and modify your main .cpp file to look like this:
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 | #include "stdafx.h" #include <gl/glut.h>
// One-time initializtion logic void init( void ) { printf( "OpenGL version: %s\n", (char*)glGetString(GL_VERSION)); printf( "OpenGL renderer: %s\n", (char*)glGetString(GL_RENDERER));
//Configure basic OpenGL settings glClearColor(0.0, 0.0, 0.0, 1.0); glShadeModel(GL_SMOOTH); glEnable(GL_BLEND); glEnable(GL_TEXTURE_2D); }
// Main drawing routine. Called repeatedly by GLUT's main loop void display( void ) { //Clear the screen and set our initial view matrix glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT | GL_STENCIL_BUFFER_BIT); glMatrixMode(GL_MODELVIEW); glLoadIdentity();
//TODO: Perform drawing here
//We just drew to the back buffer. Now we need to swap that with the //front buffer to show it on screen. glutSwapBuffers(); }
// Entry point - GLUT setup and initialization int main( int argc, char** argv ) {
glutInit( &argc, argv ); glutInitDisplayMode (GLUT_DEPTH | GLUT_DOUBLE | GLUT_RGB); glutInitWindowSize (800, 600); glutInitWindowPosition (100, 100); glutCreateWindow( "OpenGL Test" ); glutDisplayFunc( display );
init();
glutMainLoop();
return 0; } |
Hit F5 to build and run. You should get a window with a black screen. Pat yourself on the back. You’re now ready to start coding with OpenGL.
