Open Inventor显示纹理相对OpenGL简单许多，SoTexture2节点可以非常方便的完成复杂的纹理操作，一下是一个纹理演示的例子，虽然比较简单，但是纹理的功能已经表现出来了。代码如下

#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/SoRotor.h>#include <Inventor/nodes/SoTexture2.h>#include <Inventor/nodes/SoSeparator.h>int main(int argc, char ** argv){HWND mainwin = SoWin::init(argc, argv, argv[0]);SoSeparator * root = new SoSeparator;root->ref();SoRotor * rotor = new SoRotor;rotor->rotation.setValue(SbVec3f(0, 0, 1), 1.5707963f);rotor->speed.setValue(0.05f);SoTexture2 * texture = new SoTexture2;texture->filename.setValue("elf.tga");SoCube * cube = new SoCube;root->addChild(rotor);root->addChild(texture);root->addChild(cube);SoWinExaminerViewer * eviewer = new SoWinExaminerViewer(mainwin);eviewer->setSceneGraph(root);eviewer->setDecoration(FALSE);eviewer->setTitle("a simple textured cube");eviewer->show();SoWin::show(mainwin);SoWin::mainLoop();delete eviewer;root->unref();return 0;}

IV文件如下

#Inventor V2.1 asciiSeparator {  Rotor {     rotation 0 0 1 0    speed 0.05  }  Texture2 { filename "elf.tga" }   Cube { }}
