فعال سازی OpenGL در VC 64 bit

چنانچه سیستم شما 64 بیتی است مراحل زیر را برای فعال سازی OpenGL انجام دهید.

Installing freeglut

1. Get the freeglut 2.8.1 MSVC zip file from http://www.transmissionzero.co.uk/software/freeglut-devel/
2. Extract the files to your PC.
3. There are three types of files of importance: lib (in the lib folder), header (in the includeGL folder), and dll (in the bin folder).
4. If you are using 32-bit Windows with Visual Studio 2013, the following are the easiest places to put each of these files:
   • lib files: C:Program FilesMicrosoft Visual Studio 12.0VClib
   • Header files: C:Program FilesMicrosoft Visual Studio 12.0VCincludegl
   • dll files: C:WINDOWSSystem32
5. If you are using 64-bit Windows 7 or Windows 8 with Visual Studio 2013 do the following:
• Header files: C:Program Files (x86)Microsoft Visual Studio 12.0VCincludegl
• 32-bit lib files: C:Program Files (x86)Microsoft Visual Studio 12.0VClib
• 32-bit dll files: C:WINDOWSSysWOW64
• 64-bit lib files: C:Program Files (x86)Microsoft Visual Studio 12.0VClibamd64
• 64-bit dll files: C:WINDOWSSystem32

Install GLEW

The textbook samples rely on GLEW to get extra OpenGL functionality. You should install it now.

• Download GLEW (32-bit and 64-bit versions are separated): https://sourceforge.net/projects/glew/files/glew/1.9.0/
• Find the headers, glew32.lib and glew32.dll files and install them to the same locations you used for freeglut.

Set up a freeglut program

• Start Visual Studio 2012
• Select File->New->Project
  A "New Project" Dialogue box will appear.
• Click the Visual C++ Projects Folder and select the Win32 Console Application template.
• Choose a "Name:" and a "Location:".
• Uncheck "Create directory for solution"
• Click "OK"
• In the Win32 Application Wizard, Select Application Settings, check the Empty project box, then click Finish.
• A new project has now been created. Now, we will add the main program...
• Adding new files:
  • From the main menu, select Project->Add New Item...
    An "Add New Item" Dialogue box will appear.
  • Select C++ File(.cpp) and call this file main.cpp.
  • In the editor window, type your program or copy and paste in the code.
• Inserting existing files:
  • Download the desired files
  • Put them in the project folder next to the file with the .vcproj extension.
  • Add the files to your project: from the Visual Studio menu, select Project->Add Existing Item...
    A dialog will appear that should list the files you put in the project folder. Select them and add them.
  • For example:
  • Download Angel.zip and add all the files inside to your project.
    All of Dr. Angel's code relies on a set of utility files that he wrote. I have collected the files in a .zip file for your convenience.
  • Add your OpenGL code and shaders. For example, download these sample files from the textbook add them to your project:
  • example1.cpp
  • vshader91.glsl
  • fshader91.glsl
• Build and Run:
• You should be ready to go, but you may need to specify some libraries explicitly:
• Make sure the project is selected in the Solution Explorer, not a code file, and not the Solution.
• Go to Project->Properties
• expand Configuration Properties
• expand the Linker folder
• select Input
• add these additional dependencies: opengl32.lib;glu32.lib;freeglut.lib;glew32.lib
• 64-bit configuration - 64-bit Windows only
• 64-bit Windows will compile and run a 32-bit project, but if you want to try to do 64-bit OpenGL projects, you only have to do a little extra work:
• Go to Project->Properties
• Click on Configuration Properties
• Click Configuration Manager
• Select New... from Active solution platform:
• Select the new platform x64, and copy settings from Win32
