Open Inventor练习-文件存储

Open Invenor采用SoWriteAction或SoOutput写三维数据格式到文件，如下是具体实现。

#define COIN_DLL #define SOWIN_DLL // 加载COIN库文件 #ifdef _DEBUG #pragma comment(lib, "SoWin1d.lib") #pragma comment(lib, "Coin3d.lib") #else #pragma comment(lib, "SoWin1.lib") #pragma comment(lib, "Coin3.lib") #endif // 添加COIN头文件-Window操作显示库和节点库 #include <Inventor/Win/SoWin.h> #include <Inventor/Win/viewers/SoWinExaminerViewer.h> #include <Inventor/nodes/SoCube.h> #include <Inventor/nodes/SoDirectionalLight.h> #include <Inventor/nodes/SoMaterial.h> #include <Inventor/nodes/SoPerspectiveCamera.h> #include <Inventor/nodes/SoTransform.h> #include <Inventor/nodes/SoSeparator.h> #include <Inventor/actions/SoWriteAction.h> int main (int argc, char** argv) { HWND win = SoWin::init(argv[0]); if (win == NULL) exit(1); SoSeparator* root = new SoSeparator; root->ref(); SoMaterial* mSilver = new SoMaterial; mSilver->ambientColor.setValue(.2f, .2f, .2f); mSilver->diffuseColor.setValue(.6f, .6f, .6f); mSilver->specularColor.setValue(.5f, .5f, .5f); mSilver->shininess = .5; root->addChild(mSilver); root->addChild(new SoCube); SoWriteAction wa; wa.getOutput()->openFile("test.iv"); wa.getOutput()->setBinary(FALSE); wa.apply(root); wa.getOutput()->closeFile(); SoWinExaminerViewer* x = new SoWinExaminerViewer(win); x->setSceneGraph(root); x->setTitle("foo"); x->show(); SoWin::show(win); SoWin::mainLoop(); return 0; }
