Overview

DirectX 9 Graphics: The Definitive Guide to Direct3D provides a detailed and comprehensive guide to getting started with DirectX, with a specific focus on Direct3D, a technology designed to create interactive multimedia products. This book demystifies DirectX, starting with the basics of setting up a DirectX application and finishing with the intricacies of real-time 3D animation. Learn how to:
• Create and render 3D worlds.
• Use index and vertex buffers to represent 3D primitives.
• Apply 3D mathematical theory to graphic design.
• Export 3D models from 3D rendering applications and import them into DirectX as meshes.
• Save and load data using X files.
• Create snow, rain, fog, and more using point sprites and particle systems.
• Animate pixel data on textures.
• Enhance your game world with real-time lighting and texture mapping.
• Employ skeletal animation to animate meshes.
