如何在 OpenSceneGraph 中缩放/旋转/移动资产

Question

I am totally new with OpenSceneGraph

I can open and save an OSG asset. I need to do some simple transformations on it, like dimension scaling/rotation/translation.

It seems a pretty easy task, anyway I can't find any quick documentation :/

osg::ref_ptr<osg::Node> rectangle = osgDB::readNodeFile("../../inputs/Rectangle.osg");

// define simple transformation matrix
// apply  simple trnasformation matrix

osgDB::writeNodeFile(*rectangle, "../../outputs/saved.osg");

Any hint?

使用类 osg::MatrixTransform， 例如参见此示例
