Two items we've used in our sample code thus far that haven't been delved into are the various device states and transforms. There are three different state variables on the device: the render states, the sampler states, and the texture states. We've only used some of the render states thus far; the latter two are used for texturing. Don't worry; we'll get to texturing soon enough. The render state class can modify how Direct3D will do its rasterization of the scene. There are many different attributes that can be changed with this class, including lighting and culling, which we've used in our application already. Other options you can set with these render states include fill mode (such as wire frame mode) and various ...
