DirectX 9 User Interfaces: Design and Implementation

Description

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.
