DirectX10 Tutorial 5: Basic Meshes

Bobby 20 Comments

Since my car has been broken for the last two days, I’ve taken off work and have been working on my Masters degree, since part of my Masters involves building a small “game engine” for AI testing, I’ve been doing some more DX10 work, so its convenient for me to quickly slap together a few more tutorials.

I covered the basics of indexed buffers and the depth testing in the last tutorial, in this short tut, I’m going to cover the basics of directX meshes. A mesh is a data structure that contains all the vertex and index buffers needed to draw an object. It’s a neater method of drawing objects as we’ll see.

Okay so it’s been a while since my last tutorial, and I apologize for that. We dealt with textures in the last tutorial, and many of you might be wondering while I handled that so early? Well mainly because D3D 10 isn’t exactly an API designed for beginners, so a critical feature required for any scene rendering (depth testing or z-buffering) is done in D3D by use of a depth stencil texture, covering textures before depth testing makes sense in this case. Remember guys I’m not going to spoon feed you, these tutorials expect you to read the SDK docs for details on the variable types and the methods, these tutorials are just to give you a running start.

Before I get to Depth Testing, let’s draw something a little more complicated that a quad, how about a cube. Using the same method as in tutorial 3 the code to draw a six sided cube is as follows: Continue reading “DirectX10 Tutorial 4: Indexed Buffers and Depth Testing” →
