Question

如何operator获取osg：matrixd中的每一行每一列元素

Answer 1

给MatrixTransform设置矩阵的方法
osg::MatrixTransform* rootnode = new osg::MatrixTransform;
rootnode->setMatrix(osg::Matrix::rotate(osg::inDegrees(30.0f),1.0f,0.0f,0.0f));
对于上述代码，osg::Matrix::rotate实际上相当于：

inline Matrixd Matrixd::rotate(value_type angle, const Vec3f& axis )
{
Matrixd m;
m.makeRotate(angle,axis);
return m;
}

Answer 2

#define NODE_MATRIX __declspec(dllimport)#endifclass NODE_MATRIX NodeMatrix : public osg::MatrixTransform{public: NodeMatrix(void);
