Shader

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 te

Benefit from the latest rendering tech developments, currently covered only in papers and talks from Siggraph, in a way any developer or technical artist using Unity can take advantage of. This book starts by introducing how shader programming works in general, the common principles of different platforms (OpenGL, Vulkan, and DirectX), and the shading languages Unity uses: Cg, GLSL, and ShaderLab. Physically Based Shader Development for Unity 2017 discusses artistic choices, presenting various techniques (such as translucency and subsurface scattering) and BRDFs (Oren-Nayar, Cook-Torrance, and Ashikhmin-Shirley), and what they can be used for. Finally you’ll cover the importance of optimizing your code by developing approximations, which achieve similar end results, but are computationally cheaper. By the end of your journey you’ll be able to develop the look of your game or Unity-rendered animated short so that it looks both unique and impressively realistic, thanks to your own custom lighting system. What You Will Learn Master shader programming Gain all you need to know about physically based shading Take almost full control of the shader subsystem Discover what you can achieve with that control Implement a custom physically based lighting system and examine the logic behind every choice Who This Book Is For Most game developers (both indie and AA) that use Unity and technical artists who are responsible for the final look of a game.

Graphics Shaders: Theory and Practice is intended for a second course in computer graphics at the undergraduate or graduate level, introducing shader programming in general, but focusing on the GLSL shading language. While teaching how to write programmable shaders, the authors also teach and reinforce the fundamentals of computer graphics. The sec

An increasing number of artists and programmers in visual effects and broadcast production now use mental ray, a high performance rendering engine for generating photorealistic images. This book details the aesthetics of rendering with mental ray. It describes the varieties of shader programming from the point of view of increasing perceptual complexity: from color to the output of the final image. It includes many example shaders, including the simplest shader possible in each category that can serve as a starting point for further customization.

The world around us is filled with subtle lighting effects, but until recently it was not possible to duplicate these real-world effects in computer games because of the limits of consumer graphics hardware. Advanced Lighting and Materials with Shaders explains the principles of lighting theory and discusses how to create realistic lighting that takes full advantage of the capabilities of modern hardware. Topics include the physics of light, raytracing and related techniques, objects and materials, lighting and reflectance models, implementing lights in shaders, spherical harmonic lighting, spherical harmonics in DirectX, and real-time radiosity.Upon reading this text, you will understand the underlying physics of light and energy; learn about the visual features of different materials and how they can be modeled for real-time graphics; find out about the different lighting models; discover how real-time techniques compare to ray tracing; learn to use the provided shader implementations to implement lights and realistic materials in real time.Accompanying CD-ROM includes all the code in the book with resources (models, textures, probes, etc.) needed to run the programs, along with the SDKs and libraries needed to build the programs and luminance Radiosity Studio, an advanced radiosity program.
