在Visual Studio 2015中運行OPENGL

Starting an OpenGL project in VS 2015 is really easy, thanks to the NupenGL.Core nuget package.

Here are really quick steps to start your first OpenGL project using the FreeGlut library to provide a Window toolkit.

Open Visual Studio 2015 Community Edition and create a new Visual Studio C++ Windows Console Application.

Keep it simple. Choose an empty project template.

Install the NupenGL.Core nuget package. From Visual Studio, Go to Tools \ NuGet Package Manager \ Manage Nuget Packages for this solution. Search for “NupenGL” and install the package.
