There exists a gap in the game programming market where beginning programmers are finding themselves without an introductory guide. Existing books focus on the 3D component of DirectX only, leaving readers without a complete understanding of DirectX. In order to fully understand DirectX and the game programming process, readers need examples that build on previous chapters to the completion of a playable game. "Beginning DirectX 9" does just that. Readers should have basic understanding of 3D math and C++. With this rudimentary experience, "Beginning DirextX 9" enables readers to create a playable game using easy-to-understand examples.
