Hi,
I tested PlanePositionManagerService and the results are still wrong.
The rotation is kept but the offset and bounds are also kept, which lock
the 2D views on the first loaded object. This seems normal because the
width and height are saved in the object.
While testing, I found that method:
mitk::SliceNavigationController::ReorientSlices, taking the plane's
normal or 2 vectors. If I save the normal before updating the plane,
update the plane and call ReorientSlices(normal), wouldn't that work? I
can't test it right now but it looks like it could pay off.

Hi,
Maybe the way the Position node stuff of the 3D-interpolation [1] is a
good hint for that. For each drawn contour it generates a PlanarCircle
as helper object. When clicking on one of these nodes, the according
plane is adjusted to be able to continue the contour.
Best,
Stefan

*Subject:* Re: [mitk-users] Special reinit
Hi Stefan, hi all,
Anyone can help me with this? Here's a better explanation of what I
need. Lets say:
1) I load a small object, place the scene as I like (zoom, rotate 3D
and axes, etc.) http://i.imgur.com/MBHAqza.png
2) I load a second object: the reference image.
http://i.imgur.com/Gy93a3a.png <http://i.imgur.com/Gy93a3a.png> This
screenshot was taken just before the automatic reinit in
RenderingManager::InitializeViews (using a breakpoint).
In the last screenshot, my goal would be to leave the planes
untouched, except for the bounds. I should be able to see the image in
the sagittal/coronal planes and I should to be able to see the image
*if* I zoom back. I know it's not currently possible in MITK. I'm
asking how to do it in the code. I tried some things but it always
produce horrors like [3] in my previous message. Any ideas how I can
achieve that?

Hi Stefan,
Thank you for your answer. I'm working in
InitializeViewsByBoundingObjects and InitializeViews, so I'm aware
of this method. If I understand correctly, it returns a geometry
with orthogonal planes (reinited, reseted?). I would gladly use
the offset/bounds of this geometry but I also want to *keep the
rotation* of the planes.
In fact, that's what I tried to do in the snippet below.
timeGeometry IS the result of
ds->ComputeBoundingGeometry3D(ds->GetAll());.

Hi,
if you want to recompute the bounding box of the scene,
mitk::DataStorage has a method for this purpose:
mitk::TimeGeometry::Pointer geo =
ds->ComputeBoundingGeometry3D(ds->GetAll());
Best,
Stefan

Betreff: [mitk-users] Special reinit
Hi all,
Lets start by saying that I know "Reinit" is not the right choice of
word in this case! A reinit would reset the axis, as it should. Lets
say, for the sake of the discussion, that I want a reinit that simply
update the scene's bounding box, nothing else, like [1] to [2] (made by
hand, so not exact!):
- No camera modification, so everything is still at the same place
- Keep the axis rotated if they were
- Resize the scene if an object was added/deleted
I tried adding this snippet in RenderingManager::InitializeViews. In
clear english: reuse the old geometry for the current plane, but update
it with the new offset and bounds that we just calculated.
auto newGeo = timeGeometry->GetGeometryForTimeStep(0);
auto oldTimeGeo = nc->GetCreatedWorldGeometry();
auto oldGeo = oldTimeGeo->GetGeometryForTimeStep(0);
oldGeo->GetIndexToWorldTransform()->SetOffset(
newGeo->GetIndexToWorldTransform()->GetOffset());
oldGeo->SetBounds(newGeo->GetBounds());
nc->SendCreatedWorldGeometryUpdate();
nc->SetInputWorldTimeGeometry(oldTimeGeo);
nc->Update();
...
This doesn't work; it throws the planes in strange places [3], probably
because I broke their affine matrix. I tried many things but my biggest
success was to remove the call to SetInputWorldTimeGeometry [4]. I
checked in DisplayInteractor::Rotate to see if there was a way to find
the old rotation applied to the plane but it doesn't seem to be
possible.
Anyway, I'm mostly wondering how YOU, the mitk experts :), would do it.
Thank you for your time.
