OSG导入一个简单的模型，简单但很基础再根据需要组装其他零部件就OK了！-OSG import a simple model, simple but very basic re-assemble other components needed to OK!

基于分层vs2010 +用OSG详细节点示例中,主要实现对象加载迅速,选择地图呈现,用OSG实现模型的负载 -Based on layered vs2010+ detailed node example using OSG, main implementation object loads quickly, map rendering, using OSG implementation model of load

基于vs2010+OSG的细节层次节点示例，主要实现对象的快速载入，键盘控制其移动。-Based on hierarchical vs2010+ OSG detail node example, main implementation object load quickly, keyboard control its movement
