Sorry, missed that the first time.
As I understand it you want to scale the Drawable to a given size, place it in
a
certain position?
To change the position, scale/size, or orientation of a Geode you should place
a
MatrixTransform above that node and set its matrix to do what you want. (To
change the size of a single Drawable you'd have to modify it's coordinates
directly.)
E.g. say you want to change to Geode to a certain size you could do the
following:
// node hierarchy is xform=MatrixTransform -> Geode -> drawable=Drawable
// desired size
osg::Vec3 dSize(100,100,100);
// get current bounding box
const osg::BoundingBox& bbox = drawable.getBound();
osg::Vec3 bboxSize = (bbox._max - bbox._min);
xform->setMatrix(osg::Matrix::scale(bboxSize.x() / dSize.x(),
bboxSize.y() / dSize.y(),
bboxSize.z() / dSize.z()));
This is from memory, so it may not work out of the box.
