This revolving stone plate 3D navigation is primarily scripted and optimized to be CPU efficient. It features a simple Z-Axis sort via visible=true/false. The rotation effect is realized by rotationX, quite cube like but the rotation is limited to the X-Axis. All programming is native to flash 10 as3, no third party 3D engine is used. No ENTER_FRAME loop is constantly running if no interaction with the navigation. The PerspectiveProjection including projectionCenter focalLength and fieldOfView are scripted for each button resulting in a constant appearance. The button's caption can simply be set by an array of strings. The dynamic textfield got glow and bevel filters applied. No font is embedded. TAB/SHIFT ENTER is disabled by stage.stageFocusRect. There is just one textured bitmap which is broken apart and cut to make the three sides of the revolving stone plates and its XYZ positioning is hard-coded. No preloader here, this movie is too small in KB size!
