This is a simple C++ console application to create an OpenGL window using GLUT library. The code is from "OpenGL Programming Guide (Third Edition)". I tried to show how to download and include the GLUT library file. After including the GLUT file, compiling and running the code is very simple. The source code will not work if you don't have the GLUT library. Please, download the GLUT library and include it to the specific location (explained below).
You should be able to use Visual Studio 2005 and C++. You should also have some idea about OpenGL.
Using the Code
- GLUT Installation (download GLUT library).
- Copy and paste the GLUT library files to the specific locations.
- Create a C++ console application.
- Type the code, build and execute.
Before you even start a new project, you have to download the GLUT library. You can get the latest version from this link : GLUT 3.7.6 for Windows
Click this (glut-3.7.6-bin.zip (117 KB) ) link and download the zip file in your computer.
Unzip the folder and copy the glut32.dll file and paste it to C:\WINDOWS\system. Copy the glut32.lib file and paste it to this directory C:\Program Files\Microsoft Visual Studio 8\VC\PlatformSDK\Lib. The last step is to copy glut.h file and paste it to this directory C:\Program Files\Microsoft Visual Studio 8\VC\PlatformSDK\Include\gl. The installation of GLUT library files are done. However, if you using a different Windows or different Visual Studio, the directories might be different. I'm assuming that you are using Windows Vista and Visual Studio 2005.
Create a C++ console application. You don't need a Windows application. From Visual Studio 2005, select: File ->New -> Projects. Select project types Visual C++ -> Win32 and create a Win32 Console Application.
Type the code, build and execute.
Make sure to include the
#include <GL/glut.h >
display(void)" displays a polygon.
glVertex3f(0.25, 0.25, 0.0);
glVertex3f(0.75, 0.25, 0.0);
glVertex3f(0.75, 0.75, 0.0);
glVertex3f(0.25, 0.75, 0.0);
init() initialises GLUT (sets the state):
glClearColor(0.0, 0.0, 0.0, 0.0);
glOrtho(0.0, 1.0, 0.0, 1.0, -1.0, 1.0);
Main function. Make sure to change the command-line parameter
int main(int argc, char** argv)
glutInitDisplayMode(GLUT_SINGLE | GLUT_RGB);
glutCreateWindow("A Simple OpenGL Windows Application with GLUT");
Points of Interest
Actually this program is a very simple OpenGL program. However, if you are new and if you don't know how to initialise GLUT library, it might take a little bit more time to compile the code.
