You?ve tackled the basics. You can blend textures and manipulate vertex buffers with the best of them. So what now? “Advanced Animation with DirectX” will show you how to move beyond the basics and into the amazing world of advanced animation techniques. Get ready to jump right in, because this book starts off with a bang. There is no time wasted on basic concepts that you?ve already mastered. Instead, you’ll learn the techniques you need to create seamless timing, skeletal animations, and cloth simulations. Don’t let the pros have all the fun! With “Advanced Animation with DirectX” by your side, you’ll learn how to use cutting-edge animation techniques, from real-time cloth simulations and lip-synced facial animation to animated textures and a physics-based rag-doll animation system. If you’re bored with the basics and ready to get down to the nitty-gritty of truly spectacular animation with DirectX, you’ve come to the right place.
