Chapter 4. Primitives, Models, and Sprites
In the majority of Away3D projects, the contents of a scene can be split into three categories. Primitives are simple 3D geometric shapes (such as the
Cube primitive shown in the previous chapter) generated internally by the engine from preset collections of properties. Models derive their geometry from imported 3D file formats such as
.obj files that are created using 3D modeling software. Sprites in 3D are flat images that scale with distance but ignore rotation, as if they are constantly facing the camera.
You obviously don't need to know everything about the different content types to ...
