Mehrere Vollbild-Fenster mit DirectX 9.0

Question

Dies ist ein bisschen ein Randfall, aber ich entwickle ein Spiel, das mehrere Monitore verwendet. Aus Gründen, die nicht in den Rahmen dieser Frage fallen, verwende ich eine "Mehrgeräte-Methode" anstelle von Swap-Ketten. Mein Code ist ähnlich wie das folgende Beispiel:

http://www.codesampler.com/dx9src/dx9src_1.htm#dx9_multiple_devices

Was mit ich bin zu kämpfen, und was ich keine Dokumentation über finde, ist, ob es möglich ist, beiden Fenster in echtem Full-Screen laufen (dh d3dpp.Windowed = FALSE;). Momentan bekomme ich eine 'ungültige params' HRESULT beim zweiten Aufruf CreateDevice. Es funktioniert gut, wenn ein der Fenster Vollbild ist, aber nicht beides. Ich hoffe, es gibt eine Einstellung, obwohl diese Arbeit zu machen ...

Prost im Voraus

Answer 1

Nach der Direct3D 9 Dokumentation (Working with Multiple Monitor Systems): „Die praktische Auswirkung ist, dass eine Multi-Monitor-Anwendung mehr Geräte platzieren im Vollbildmodus, aber nur, wenn alle diese Geräte für verschiedene Adapter sind, wurden von demselben Direct3D9-Objekt erstellt und alle haben das gleiche Fokusfenster. "

Sie werden feststellen, dass es zwei Fenstergriffe pro Gerät Initialisierung gibt; das Präsentationsfenster und das Fokusfenster. Das Fokusfenster (übergeben an IDirect3D9::CreateDevice) wird verwendet, um Ereignisse wie den Wechsel von Vordergrund zu Hintergrund oder Alt + Tab zu behandeln. Das Präsentationsfenster wird an die Struktur D3DPRESENT_PARAMETERS übergeben und dient ausschließlich als Zeichenfläche für Direct3D.

Sie sollten eines der von Ihnen erstellten Fenster (wahrscheinlich das erste) als Fokusfenster markieren. Teilen Sie das Fokusfenster auf verschiedenen Geräten, aber halten Sie die "Canvas" - (Präsentations-) Fenster getrennt.

EDIT:This kann Ihnen auch helfen.

erstellen Sie ein Fokusfenster für beide Geräte.

(optional) Erstellen Sie ein Gerätefenster für den ersten Adapter.

erstellen Sie ein Gerätefenster für den zweiten Adapter.

Erstellen Sie einen Direct3D9-Kontext.

Verwenden Sie dies, um beide Geräte zu erstellen.

Erstellen Sie das erste Fullscreen-Gerät mit dem Fenster für den gemeinsamen Fokus und (optional) dem ersten Gerätefenster.

Erstellen Sie das zweite Vollbildgerät mit dem Fenster für den gemeinsamen Fokus und dem zweiten Gerätefenster.

Setzen Sie das erste Gerät zurück.

Das Fenster für den gemeinsamen Fokus wird direkt als Parameter an CreateDevice übergeben.

Die Gerätefenster werden in der Struktur der Präsentationsparameter übergeben.

Answer 2

Q> Zeit eine 'ungültig params' HRESULT Ich erhalte, wenn Create das zweite Mal aufgerufen wird.Es funktioniert gut, wenn eines der Fenster Vollbild ist, aber nicht beides.

Da Sie zwei verschiedene Geräte mit der gleichen Adapter-ID 0 erstellt haben. Verwenden Sie die ID des Adaters als 1 für den zweiten Geräteaufruf!

Wichtiger Schritt nach der Erstellung von Gerät 2 oder 3 oder 4 ... ist das Zurücksetzen des Geräts auf (Standardgerät-ID 0).

Create Device 1 
Create Device 2 
........ 
........ 
Create Device n  
Reset Device 1

Bitte beachten Sie, dass ich einige Codezeilen aus dem Beispielcode hinzugefügt oder geändert habe, der von dem Weblink stammt, den Sie in Ihrer Frage erwähnt haben.
