Visual Studio

Microsoft gives visual studio to students for free. It can be accessed from

You need to verify that you are a student before you can download. You can use your CalNet ID to verify your student status. You can download Visual Studio 2005 or 2008. Since I have more experience with 2005, I will advise you to install this. Please dont install the Visual Studio express editions as they have known to have some issues while compiling. While installing, you need to install visual C++ and the tools. You can probably skip intalling other components (SQLServer etc.) if you are running short of disk space.

OpenGL

Once you have installed Visual Studio you need to to install some extra libraries for OpenGL. Unzip the file GL.zip to a temporary folder. Copy the files in each of the 3 folders to the folders listed below

bin : C:\Windows\system32\
lib : C:\Program Files\Microsoft Visual Studio 8\VC\lib
inc : C:\Program Files\Microsoft Visual Studio 8\VC\include

Now you should be able to compile and run OpenGL code
