If you're a Windows game developer interested in 3D, here are two reasons you'll find Inside Direct3D especially valuable: First, it demonstrates how to create a complete game, not just tiny fragments integrating Direct3D with the rest of DirectX to build a complete (and quite cool) game. Second, it focusing on the Direct3D Immediate Mode API which is far more challenging, but also far more efficient than the alternative, Direct3D Retained Mode. This is information that's tough to find. In fact, many advanced developers, upon figuring it out, choose to keep the knowledge to themselves, as a proprietary competitive advantage. But it's here along with a barrelful of code, modeling tools, the official DirectX 7 SDK, and more.
As you build your game, you'll master writing the code to handle both windowed and full-screen functionality; create complex 3D worlds containing streets and fields; add 3D objects to your scenes, and color and texture them; add animated characters, music and sound; integrate keyboard, joystick, and mouse input; add fog, alpha blending, and more. There's even a chapter on adding networked play with Microsoft's DirectPlay.
Whether you're building a Windows game, simulation, or virtual reality product, Inside Direct3D contains all the Direct3D wizardry you're looking for.
