Coding in 3D
It's time for us to put our theory into practice and create our first 3D scene. To keep things simple, we will go through the steps of placing a cube in 3D space. This is also going to be the start of our 3D game, so let's start by creating a brand new project in Visual Studio.
Creating the project
When we created a project for our 2D game, we started with a standard Windows project and then removed (or ignored) the items that we didn't need to use. In fact, the standard Windows project has a lot of overhead that we don't need. This is because the Windows project template assumes that Windows is going to be in charge of rendering and processing. This came in useful for our 2D project, but just adds a lot of extra code that we don't need.
For this project, we will start with a blank Windows project and then add the necessary code to initialize and create an OpenGL window. Then, we will work our way up from there:
Begin by opening Visual Studio.
Once Visual Studio is open, create a...
