Managed DirectX® 9 Kick Start: Graphics and Game Programming

Defining the Mesh

While there are many times when you may want to manually create vertex and index data, it's also common to want to load existing vertex data from an external source, such as a file. A common file format holding this data is an .X file. In the previous chapters, large portions of the code were there just to create simple objects that were to be rendered. While for the simple cubes and triangles, it wasn't all that bad, imagine trying to write similar code that was creating an object that had tens of thousands of vertices instead of the 36 that were used for the cube. The amount of time and effort to write this code would be substantial.

Luckily there is an object in Managed DirectX that can encapsulate storing and loading vertex ...
