Release Date: 2004
Because graphics systems for video games and game console hardware have become more complex, graphics applications must also advance. This is where programmable vertex and pixel shaders come in. This book shows how to write assembly language for programming the vertex shader and pixel shader hardware using DirectX 9 and covers the fundamentals of programming vectors using SIMD methodology in conjunction with the Direct3D 9 application interfaces. Features: Find out about the valid vertex shader and pixel shader instruction sets; Learn how branching and branchless code can be used for flow control; Understand the vertex shader instructions that support matrices; Discover how to use quaternions to accurately represent rotating objects; Use texturing with both vertex and pixel shaders, including bump mapping.
DirectX 9 User Interfaces
Companion CD included with Paint Shop Pro 8 evaluation edition!Interfaces strongly affect how an application or game is received by a user, no matter which cutting-edge features it may boast. This unique book presents a comprehensive solution for creating good interfaces using the latest version of DirectX. This involves building an interface library from the ground up. Divided into three sections, the book discusses the foundations of interface design, the construction of a feature-rich interface library, and the creation of a fully functional media player in DirectShow.
Advanced Lighting and Materials with Shaders
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.
