把纹理和模型一起打成.IV包

添加纹理,创建iv文件.

//------------例子---------------

int _tmain(int argc, _TCHAR* argv[])
{

 //
 Widget myWindow = SoXt::init(argv[0]);
 if (myWindow == NULL)
  exit(1);

 SoSeparator *root = new SoSeparator;
 root->ref();

 SoTexture2 *texture=new SoTexture2;
 texture->filename="照片001.jpg";
 root->addChild(texture);

 SoCoordinate3 *coord=new SoCoordinate3;
 coord->point.set1Value(0,0,0,0);
 coord->point.set1Value(1,0,1,0);
 coord->point.set1Value(2,1,1,0);
 coord->point.set1Value(3,1,0,0);
 root->addChild(coord);

 SoFaceSet *face=new SoFaceSet;
 face->numVertices.setValue(4);
 root->addChild(face);

 // Set up viewer:
 SoXtExaminerViewer *myViewer = new SoXtExaminerViewer(myWindow);
 myViewer->setSceneGraph(root);
 myViewer->setTitle("Examiner Viewer");
 myViewer->show();
 
 SoXt::show(myWindow);
 SoXt::mainLoop();
 
 SbString ivFile;
 ivFile="demo.iv";
 SoWriteAction wa;
 wa.getOutput()->setBinary(true);
 wa.getOutput()->openFile(ivFile.getString());
 wa.apply(root);
 wa.getOutput()->closeFile();
 
 root->unref();

 return 0;
}
