This time around, we are going to dig into Chapter 9 of

. We will be implementing the BlendDemo in the next couple of posts. We will base this demo off our previous example, the

. We will be adding transparency to our water mesh, a fog effect, and a box with a wire texture, with transparency implemented using pixel shader clipping. We'll need to update our shader effect, Basic.fx, to support these additional effects, along with its C# wrapper class. We'll also look at additional DirectX blend and rasterizer states, and build up a static class to manage our these for us, in the same fashion we used for our InputLayouts and Effects. The full code for this example can be found on GitHub at

, under the BlendDemo project. Before we can get to the demo code, we need to cover some of the basics first, however.
