Let's just remove the camera bar. Oh wait. There are several cables leading into the side of the display assembly. Our bet is that these control the parallax barrier, used to generate that awesome glasses-less 3D effect. What's a parallax barrier? Imagine placing a very small picket fence in front of your screen, so that when you look at the display, each eye sees different pixels while they peer around the fence boards.

  • Then, with a combination of the magic of geometry, and the new face-tracking "super-stable 3D", the 3DS knows which pixels each eye can see, and draws two overlapping versions of the same scene—one for each eye. The combination of these two versions gets slapped together in your thinkpan as a sweet, sweet stereoscopic 3D image.

カメラバーを外してみましょう。 あっ、ちょっとその前に。

ディスプレイアセンブリの側面にケーブル数本が接続しています。これらのケーブルが、3Dメガネなしで実現する素晴らしい3D効果を生み出す視差バリアを制御しているのではないかと考えています。

視差バリアとは何でしょうか? スクリーンの前に極小の縦格子フェンスが置かれていると想像してください。ディスプレイを見るとき、フェンスボード周辺が見えながらも、右目左目は異なる映像を捉えるのです。

そして、幾何学がなすマジックと新しい顔追跡システムによる"超安定3D"の組み合わせで、3DSはそれぞれの目がどの映像を見ているか識別し、同じシーンであっても左右の目に合わせて2タイプの重複する映像を作り出すのです。そしてこれらが脳内で1つの映像として組み合わさると、迫力のある高度な立体3D画像に変身するのです。
