Billboards are basically textured squares (two triangles) that point towards the camera and appear to be a 3D model. They are cheaper and easier to work with than models many early 3D games consisted mainly of billboards. Billboards are still used to fake 3D objects.

The XNA 3DAudio example from

has a good example of using billboards. This example also demonstrates 3D audio.

Quad Drawer Class

SpriteEntity/Quad Sprite I changed the name

I've added these two classes to our IntroGameLibrary Project. Here's an example. I did change the projection view size and some of the scales of the billboards.

A mesh is a collection of vertices, faces and edges that define a 3d shape. XNA can import .X or .Fbx files. .X files are Files created for DirectX, while FBX is an platform independent 3D mesh file type.

FBX is now a platform and has its own API and SDK from Autodesk

Mesh Example


You can get some free models from TurboSquid, or you can make your own models with Blender.


Blender is a free 3D program. It can export fbx models for xna.
