Acquisition Adapter does not support tranformations?

[Anant Vemuri]

Hi,

Although the acquisition adapter sets the transform ID, from the
config, it does not seem that it does anything with the transform to
manipulate the acquisition. Could you please confirm for me if this is
a bug?

Thanks
Anant.

No, it does :

http://code.google.com/p/fw4spl/source/browse/Bundles/LeafVisu/visuVTKAdaptor/src/visuVTKAdaptor/Acquisition.cpp?r=8ae4105a792cac5b40ab7c064df197f6b07d177d#93

The transform Id is passed through to the embeded adaptor (reconstruction).

I am not sure how its working. I am doing the following:

<adaptor id="myAcquisitionAdaptor" class="::visuVTKAdaptor::Acquisition" objectId="PatientAcq">

<config renderer="vtkRender1" picker="" transform="vtkTrf2"  />

</adaptor>

Do I need to create an updater service for Reconstruction?

Looks good to me. To observe an acquisition transformation, make sure you are actually working (or modifying) on vtkTrf2. Maybe you missed the notification ?

No.

Hmm, as Julien noticed to me, in the branch you are using (fw4spl_0.6) the reconstruction adaptor don't pass the transform. I patched it and it should be available on googlecode soon.

Hi,

I pulled the latest change. It seems to be working, but when I try to
apply specific transformation with only translation on one of the
axis, I don't get any result. Only the rotation part of the transform
seems to be working. I apply the following transforms.

NOTE: the first nine parameters are rotation matrix parameters and the
last three translation. I append a final row of [0,0,0,1] to make it
4x4.

1,0,0,0,1,0,0,0,1,1000,0,0
1,0,0,0,1,0,0,0,1,2000,0,0
1,0,0,0,1,0,0,0,1,3000,0,0
1,0,0,0,1,0,0,0,1,4000,0,0
1,0,0,0,1,0,0,0,1,5000,0,0
1,0,0,0,1,0,0,0,1,6000,0,0
1,0,0,0,1,0,0,0,1,7000,0,0
1,0,0,0,1,0,0,0,1,8000,0,0
1,0,0,0,1,0,0,0,1,9000,0,0
1,0,0,0,1,0,0,0,1,10000,0,0
1,0,0,0,1,0,0,0,1,11000,0,0
1,0,0,0,1,0,0,0,1,12000,0,0
1,0,0,0,1,0,0,0,1,13000,0,0
1,0,0,0,1,0,0,0,1,14000,0,0
------------------------------
-1,0,0,0,-1,0,0,0,1,15000,0,0 <-- On this one it flips across as
expected. But in the rest of the cases, it does nothing at all.
------------------------------
1,0,0,0,1,0,0,0,1,16000,0,0 <-- Flips back to its original
position.
1,0,0,0,1,0,0,0,1,17000,0,0
1,0,0,0,1,0,0,0,1,18000,0,0
1,0,0,0,1,0,0,0,1,18000,0,0
1,0,0,0,1,0,0,0,1,20000,0,0
1,0,0,0,1,0,0,0,1,21000,0,0
1,0,0,0,1,0,0,0,1,22000,0,0
1,0,0,0,1,0,0,0,1,23000,0,0
1,0,0,0,1,0,0,0,1,24000,0,0

Is there something that I am missing? Also, want to confirm that the
only change you made was to the Reconstruction adaptor right, since I
just copied and pasted the latest code of ../visuVTKAdapator/
Reconstruction.cpp into my source.

Thanks!

Anant.

If i understand how you write your matrices, the first one of the given list is :

1, 0, 0, 0,
0, 1, 0, 0,
0, 0, 1, 0,
1000 , 0, 0, 1

and should be

1, 0, 0, 1000,
0, 1, 0, 0,
0, 0, 1, 0,
0 , 0, 0, 1


I think that is the source of your problem.

You are right, my bad...in the parser for the string, I copied part of the code but did not change the indices. I will fix it and try.
