 # 3D rendering
 
-coming soon, its in the engine, but not yet documented
+In Codename Engine, there is Away3D integration with a few tools to make the process easier for you.
+
+Here's a simple way to add a Cube primitive into your scene.
+Just take this method and apply it to a stage or something, and you'll get your cube. Though you'll need to do more work to get the cameras and their perspectives to line up correctly. a sugge
+```haxe
+import flx3d.Flx3DView;
+
+import away3d.entities.Mesh;
+import away3d.primitives.CubeGeometry;
+
+function create() {
+    cube = new Mesh(new CubeGeometry()); // This is your Cube
+    cube.z -= 200; // Move it back a bit so you can see it on the camera
+	cube.rotationY = 23; // Add some rotation so you can see it's 3D
+	cube.rotationX = 45;
+
+    scene3D = new Flx3DView(0, 0, FlxG.width, FlxG.height); // This is what's creating the 3D world
+	scene3D.screenCenter();
+    scene3D.addChild(cube);
+
+    add(scene3D); // The 3D View works just like any other sprite so it will have to be added like one
+}
+```
+
+## Temporary information (clean up later)
+
+From now on, assume that `scene3D` is set up like this
+```haxe
+scene3D = new Flx3DView(0, 0, FlxG.width, FlxG.height);
+```
+
+Here's just a few function I found that I think would be useful to know about
+
+```haxe
+scene3D.addModel(assetPath:String, callback:Asset3DEvent->Void, ?texturePath:String, smoothTexture:Bool = true);
+
+scene3D.addChild(childObject);
+```
