<DIV>Hi Fucang,</DIV>
<DIV> </DIV>
<DIV>I just looked into the vtkImageActor
class we are using to display
the</DIV>
<DIV>image. The RequestSetSliceNumber(ContinuousIndexType
index) function</DIV>
<DIV>of igstkImageRepresentation class, will send
this slice parameters</DIV>
<DIV>down to the vtkImageActor's SetDisplayExtent(int
extent[6]), so there</DIV>
<DIV>is an actual truncation here.</DIV>
<DIV> </DIV>
<DIV>I guess the vtkImageActor is not doing
the interpolation here. So it</DIV>
<DIV>can only display integer slice number.
The jumping is caused by the</DIV>
<DIV>incorrect truncation. We can put a temp
fix by adding the following</DIV>
<DIV>lines into the FourViewsTrackingWithCT.cxx file
after line 991(after</DIV>
<DIV>we get the continuous index),</DIV>
<DIV> index[0] = int(
index[0] + 0.5 );</DIV>
<DIV> index[1] = int(
index[1] + 0.5 );</DIV>
<DIV> index[2] = int(
index[2] + 0.5 );</DIV>
<DIV>This should fix the jumping problem.</DIV>
<DIV> </DIV>
<DIV>Let me know if this works for
you,</DIV>
<DIV> </DIV>
<DIV>Thank you,</DIV>
<DIV> </DIV>

<DIV>> Hi Fucang,</DIV>
<DIV>> </DIV>
<DIV>> I fixed the problem
in the IGSTK main
repository, by adding</DIV>
<DIV>> TransformPhysicalPointToContinuousIndex() function,
into the</DIV>
<DIV>> igstkImageSpatialObject class.</DIV>
<DIV>> </DIV>
<DIV>> But the example
application you are running
is in the Sandbox.</DIV>
<DIV>> </DIV>
<DIV>> You might need to
check on two things:</DIV>
<DIV>> </DIV>
<DIV>> First, after you update
the IGSTK main repository,
you have to </DIV>
<DIV>> CMake</DIV>
<DIV>> the Sandbox again, this
way, the Sandbox will
get the latest </DIV>
<DIV>> source</DIV>
<DIV>> from main repository,</DIV>
<DIV>> </DIV>
<DIV>> Second, you have updated
the FourViewsTrackingWithCT application
in</DIV>
<DIV>> the Sandbox. You can
double check by looking
into the</DIV>
<DIV>> DrawPickedPoint() function in
the FourViewsTrackingWithCT .cxx
file.</DIV>
<DIV>> See whether it's using
the continuous index.</DIV>
<DIV>> </DIV>
<DIV>> I will send you
the executables in another
separate email, because</DIV>

the mailing list.</DIV>
