Looking through OSG’s history with this function, I’m guessing the way I need this implemented did not happen, or I’m dealing with a software bug (on my part or OSGs part)…having problems knowing if I’ve even using this function properly.
Doing this below seem to ignore my eye point translation and is only taking the rotation. If an eyepoint offset translation cannot be set, any ideas on how I can get both a translation and rotation as an eyepoint offset?
cameraRotation.makeRotate( osg::DegreesToRadians(-90.0), osg::Vec3d(1, 0, 0), 0,osg::Vec3d(0, 1, 0), osg::DegreesToRadians(-heading_offset),osg::Vec3d(0, 1, 0 ) ) ;
osg::Matrixd cameraoffset = cameraRotation * cameraTrans;
viewer_.getCamera(0)->setOffset(cameraoffset.ptr());
I’m checking the code above with this function, where I would have expected to get the translation offset added into my translation. “inverseMatrix.getTrans();”
XXX::PreFrame(const Producer::Camera &cam) { //this is our position osg::Matrix model = osg::Matrix(cam.getViewMatrix());
osg::Matrix inverseMatrix; osg::Matrix rotationtest; rotationtest.makeRotate(-M_PI/2.0, 1, 0, 0);
inverseMatrix.invert( model ); inverseMatrix = rotationtest * inverseMatrix;
xyzlocation_ = inverseMatrix.getTrans(); }
as an FYI, I’m using osg’s manipulators… |
