参照网上下的动画例子做动画，总提示animation.exe已退出工作

Crystal

我想做一条直线变形的动画，于是在网上下了对折硬纸的动画源代码，参照那个写直线变形的代码，却总是执行时提示animation.exe已退出工作，请关闭程序，而网上下的代码运行时则没有问题，是我写的代码不对吗，请大神赐教，看我哪里写的不对。

你没有为geomatry添加法线数组的原因，osgUtil::SmoothingVisitor smv;
    smv.smooth( *line );对直线没用，
你应该为变形体添加法线数组       
osg::ref_ptr<osg::Vec3Array> NormalVertices = new osg::Vec3Array;//添加法线数组
        NormalVertices->push_back( osg::Vec3(0,0,1) );//添加法线数组
        NormalVertices->push_back( osg::Vec3(0,0,1) );//添加法线数组

        osg::ref_ptr<osg::Geometry> line = new osg::Geometry;
        line->setVertexArray(vertices);
        line->setNormalArray(NormalVertices);//添加法线数组
变形体的两个geometry都添加
