Since the current edition, most of the graphics concepts have not changed, but the graphics hardware has evolved signicantly. Desktop GPUS are quite powerful these days. The latest GPUs are important for the popular topics of virtual reality (VR), and augmented reality (AR). To allow fine-grained control of these aspects of graphics and computing, we now have new graphics APIs, namely, Direct3D 12 and Vulkan. The primary goal of the 3rd edition is to cover the multi-engine view of modern GPUs (graphics, compute,copy) and to talk specically about Direct3D 12 and Vulkan. The book will also provide C++ source code libraries that wrap the features of Direct3D 12 and of Vulkan.
