あなたが見ることができるように図

Question

の内側にカーブを移動、最初の写真で、私は同じカーブ位置で2つの同じ2つのサブプロットを、持っています。しかし、私はサブプロットの1つのカーブ位置/ビュー角度を変更する必要があります（左または右の場合は問題ありません）。唯一の作業コマンドはCameraViewAngleですが、両方とも変更されていますが、私はなぜか分かりませんし、それぞれ別々に変更する必要があります。 画像2のように、両方の視野角が変わります。私はむしろカーブの位置だけを狂わせたいと思う。

私が使用しているコードは次のとおりです。

function [pointsQRS, pointsP, pointsT] = VCG (pointsQRS,pointsP,pointsT)

linkaxes([ax1, ax2]) 

私はそれがGoogleの段ボールを使用して3D立体視を実現するために、それを変更する必要があります。 ご協力いただきありがとうございます！

PS：例3と同じようにしたいです。 3つの3Dカーブは接続されていません。接続されていれば、一方が移動している間はもう一方は同じように動いた。

Answer 1

私は部分的にそれを解決するために管理。

CameraViewAngleを変更すると、カーブのサイズが変更されるので、変更しないでください。

CameraPositionの角度をに設定する代わりに、ax1と異なるように設定しますが、ターゲットから同じ距離を保ちます。代わりlinkpropを使用する

、Iはaddlistenerを使用し、ax1のCameraPositionが変更されたときax2のCameraPositionを設定するコールバック関数を実装します。
