实现三维模型的交互，如添加新的模型，改变模型的颜色等等，部分代码自己写的，可能功能不算特别完善，共同改进-private void moxingjiaohu ToolStripMenuItem_Click(object sender, EventArgs e)



private void axSceneControl1_OnMouseDown(object sender, ISceneControlEvents_OnMouseDownEvent e)



public void AddMultipatch(IScene pScene, IMultiPatch pMultiPatch, string layerName, IColor color)
