연습: WPF에서 호스팅할 Direct3D9 콘텐츠 만들기

아티클
08/10/2011

이 연습에서는 WPF(Windows Presentation Foundation) 응용 프로그램에서 호스팅하기에 적합한 Direct3D9 콘텐츠를 만드는 방법을 보여 줍니다. WPF 응용 프로그램에서 Direct3D9 콘텐츠를 호스팅하는 방법에 대한 자세한 내용은 WPF 및 Direct3D9 상호 운용성를 참조하십시오.

이 연습에서는 다음 작업을 수행합니다.

Direct3D9 프로젝트를 만듭니다.
WPF 응용 프로그램에서 호스팅할 수 있도록 Direct3D9 프로젝트를 구성합니다.

작업을 마치면 WPF 응용 프로그램에서 사용할 수 있는 Direct3D9 콘텐츠가 포함된 DLL이 만들어집니다.

사전 요구 사항

이 연습을 완료하려면 다음 구성 요소가 필요합니다.

Visual Studio 2010.
DirectX SDK 9 이상

Direct3D9 프로젝트 만들기

첫 번째 단계는 Direct3D9 프로젝트를 만들고 구성하는 것입니다.

Direct3D9 프로젝트를 만들려면

C++에서 D3DContent라는 이름의 Win32 프로젝트를 새로 만듭니다.

Win32 응용 프로그램 마법사가 열리고 시작 화면이 표시됩니다.
다음을 클릭합니다.

응용 프로그램 설정 화면이 나타납니다.
응용 프로그램 종류 섹션에서 DLL 옵션을 선택합니다.
마침을 클릭합니다.

D3DContent 프로젝트가 생성됩니다.
솔루션 탐색기에서 D3DContent 프로젝트를 마우스 오른쪽 단추로 클릭하고 속성을 선택합니다.

D3DContent 속성 페이지 대화 상자가 열립니다.
C/C++ 노드를 선택합니다.
추가 포함 디렉터리 필드에 DirectX 포함 폴더의 위치를 지정합니다. 이 폴더의 기본 위치는 %ProgramFiles%\Microsoft DirectX SDK (version)\Include입니다.
링커 노드를 두 번 클릭하여 확장합니다.
추가 라이브러리 디렉터리 필드에 DirectX 라이브러리 폴더의 위치를 지정합니다. 이 폴더의 기본 위치는 %ProgramFiles%\Microsoft DirectX SDK (version)\Lib\x86입니다.
입력 노드를 선택합니다.
추가 종속성 필드에 d3d9.lib 및 d3dx9.lib 파일을 추가합니다.
솔루션 탐색기에서 프로젝트에 D3DContent.def라는 이름의 모듈 정의 파일(.def)을 새로 추가합니다.

Direct3D9 콘텐츠 만들기

최상의 성능을 얻으려면 Direct3D9 콘텐츠에서 특정 설정을 사용해야 합니다. 다음 코드에서는 최상의 성능 특성을 가진 Direct3D9 화면을 만드는 방법을 보여 줍니다. 자세한 내용은 Direct3D9 및 WPF 상호 운용성을 위한 성능 고려 사항을 참조하십시오.

Direct3D9 콘텐츠를 만들려면

솔루션 탐색기를 사용하여 다음과 같은 이름을 가진 C++ 클래스 세 개를 프로젝트에 추가합니다.

CRenderer(가상 소멸자 포함)

CRendererManager

CTriangleRenderer
