Re: [osg-users] Restoring a Viewer's MatrixManipulator
Hi, also have a look at these old emails. It is still something I want to add to the manipulators to enable smooth switching between them. Basically, the internal state of the manipulator is not fully encoded in the view matrix. http://article.gmane.org/gmane.comp.graphics.openscenegraph.user/8610 jp Shiina Ringo wrote: Hi,Phil I just have met the same problem , like the switching of 2 MatrixManipulators , that the home position is not the position which is like the default position.

Re: [osg-users] Restoring a Viewer's MatrixManipulator
Greetings, all. I've been a lightweight user of OSG for some time now, and have a fair understanding on how the basic components fit together. There's something I'm missing, though, in my current quest. I'm adding XML persistence to my OSG objects. In general, I wrap OSG objects in my own objects, and it's those objects that will be doing the persisting. For the most part, all is well. My Viewer object, though, is having trouble with restoring its camera. I've succeeded in restoring the camera to its home position, but have not been able to restore its current position (getMatrix(), setByMatrix()). My Viewer object uses either a MatrixManipulator or a Camera, and my XML implementation persists the values of those correctly. With respect to the MatrixManipulator, I'm doing (paraphrased): myViewerObject - its osgViewer -setCameraManipulator( a restored myMaxtrixManipulator - its osgMatrixManipulator); // I expect this to do the whole job, but... myMatrixManipulator - its osgMatrixManipulator = myViewerObject - its osgViewer -getCameraManipulator(); // setCameraManipulator seems to create a copy, and I want to be wrapping the current one. // Since the above seems to restore just the home position and not the current, I've tried adding: Matrixd testMatrix = myViewer - its osgViewer - getCameraManipulator() -getMatrix(); // testMatrix is correct. myViewerObject - its osgViewer -getCameraManipulator() -setByMatrix( testMatrix); // These last seem redundant (and aren't succeeding), but I'm trying things where things seem broken. I've disabled all home() calls, and yet, after loading a persisted MatrixManipulator, I see my scene from the home position, not the saved position. I imagine I have a flawed mental model of some facet of this. Can someone point me in the right direction? Thanks, in advance, Phil Philip A.
