Hi:
I find something strange like this:
osg::Matrix _matrix;
osg::ref_prt<osg::MatrixTransform> PAT1 = new osg::MatrixTransform();
_matrix.setTrans(osg::Vec3(10.0f,10.0f,0.0f));
PAT1 ->setMatrix(_matrix);
osg::ref_prt<osg::MatrixTransform> PAT2 = new osg::MatrixTransform();
PAT2 ->setMatrix(_matrix);
osg::ref_prt<osg::MatrixTransform> PAT3= new osg::MatrixTransform();
PAT3 ->setMatrix(_matrix);
osg::ref_prt<osg::MatrixTransform> PAT4= new osg::MatrixTransform();
PAT4 ->setMatrix(_matrix);
PAT1->addChild(PAT2->get());
PAT2->addChild(PAT3->get());
PAT3->addChild(PAT4->get());
osg::Node* node = osgDB::readNodeFile("*.ive");
PAT4->addChild(node);
I think node's final position is (40,40,0),but the actual position in
scene is(10,10,0).Do I have to accumulate the four MatrixTransform manually?
How did you calculate the actual position?
