Wie kann ich Mehrere GLSurfaceView Komponenten im gleichen Layout?

Was die Umsetzung für CoordinateSystemRenderer?

Traf ich die gleiche Anforderung heute und versucht, es tatsächlich funktioniert, dass bedeutet, Sie können 2 GLSurfaceView in ein und derselben Aktivität.

Etwas brauchen, um bemerkt zu werden,

1. In GLRender, wenn onSurfaceChanged aufgerufen wird, müssen Sie ändern Sie die Größe des viewport
2. Mit 2 GLSurfaceView die render-thread eine 2, also synchronisieren, wird das Problem aufgetreten ist. Es hängt davon ab, Ihre Umsetzung onDrawFrame.

Es gibt einen schnellen test, um die Android-API-demo im SDK GLSurfaceViewActivity

Können Sie möglicherweise wollen untersuchen, überlagerungen/unter-legen Sie Ihre Modelle im "richtigen" Bereich des Bildschirms mit einem Vollbild GLSurfaceView. Sie Mai wollen zusammen eine Art von layout-Rahmen, um diese einfacher, oder vielleicht die Verwendung mehrerer Ansichtsfenster auf die volle Bildschirm GLSurfaceView. Habe nicht versucht, diese in OpenGL ES, aber in der Regel entweder von diesen Methoden werden die für die Wiedergabe mit mehreren Ansichten die gleiche oder sogar viele verschiedene Modelle in einer einzigen Anwendung auf einem desktop-system eher als die Verwendung mehrerer GLContexts (wenn es das ist, was passiert hinter den kulissen hier).

Können Sie mehrere GLSurfaceViews aktiv und sichtbar in eine Aktivität. Jede view bekommt seine eigene GL-Kontext.
