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

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;
