新版本fbxsdk需要自己link xml2库，所以需要手动安装一下

FBX SDK场景图是通过`FbxScene`类抽象出来的。场景被组织为节点层次结构 ( `FbxNode`)。场景的根节点通过 访问`FbxScene::GetRootNode()`。场景元素（例如网格、灯光或相机）是通过将`FbxNode`与 的子类组合来定义的`FbxNodeAttribute`。 FBX SDK场景图是通过`FbxScene`类抽象出来的。场景被组织为节点层次结构 ( `FbxNode`)。场景的根节点通过 访问`FbxScene::GetRootNode()`。场景元素（例如网格、灯光或相机）是通过将`FbxNode`与 的子类组合来定义的`FbxNodeAttribute`。
