Real-Time 3D Rendering with DirectX® and HLSL: A Practical Guide to Graphics Programming

Chapter 15. Models

In this chapter, you learn how to use 3D models in your applications. You integrate a third-party library for importing myriad file formats, and you author a set of classes to represent models at run-time. Along the way, you get some more hands-on experience creating DirectX applications.

Motivation

Now that you’ve authored a couple applications, and you’ve manually specified vertices and indices, you’re probably thinking about a better way to do this. Clearly, you cannot hard-code the vertices for every object you’ll render. Instead, you’ll get your objects from an artist who uses a 3D modeling package such as Autodesk Maya or 3D Studio Max. Your job is to read these assets at runtime and extract the data necessary to render ...
