Hi, I have recently finished my fourth GP book, so far i have read: "Tricks Of The Windows Game Programming Gurus", "The Zen Of Direct3D Game Programming", "Special Effects Game Programming", and "Physics For Game Developers". For my next book I was thinking of one of the following four: "Isometric Game Programming", "Advanced 3d Game Programming With DirectX8", "Game Programming Gems", or "3D Engine Design". Does anyone know which of these would be the better choice based on whether or not i would have already covered the material involved. Or maybe there is a better choice that I have not considered? Mosh.
