How to scale/rotate/move an asset in OpenSceneGraph

[Luca Costantino]

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?

Check out the examples directory.
One example: https://github.com/openscenegraph/OpenSceneGraph/blob/master/examples/osganimate/osganimate.cpp#L247

1. Create a MatrixTransform
2. Add your rectangle as a child of that transform

3. Save the MatrixTransform node
