This book focuses on advanced rendering techniques that run on the DirectX and/or OpenGL run-time with any shader language available. It includes articles on the latest and greatest techniques in real-time rendering, including MLAA, adaptive volumetric shadow maps, light propagation volumes, wrinkle animations, and much more. The book emphasizes techniques for handheld programming to reflect the increased importance of graphics on mobile devices. It covers geometry manipulation, effects in image space, shadows, 3D engine design, GPGPU, and graphics-related tools.

Source code and other materials are available for download on the book's CRC Press web page.

Recenzijas

Praise for GPU Pro:Any professional programmer in the field will find something of interest in this volume. Im thrilled to see that this collection is in colorits about time! A wide range of topics are covered, from global illumination to image processing to mobile devices. I particularly like the fact that the book doesnt go the scholarly researcher route; the articles are written in a straightforward way to help with implementation of the idea, and code is often provided. Eric Haines, co-author of Real-Time Rendering, February 2010

I recently started reading GPU Pro and it is outstanding! I love the full color and syntax highlighting!
