[IGSTK-Users] Cross Hairs.

[Ashwath Hegde, ERS-HCLTech]

Hi,

The problem I mentioned is still present.

I remove the cross hairs from the 2D Views by using the below code.

m_CrossHair->RequestDetachFromParent();
m_view2DAxial->RequestRemoveObject(m_AxialCrossHairRepresentation);

After that  when I click on the 2D Views and draw a small ellipse on the 2D View and the 3D model my 3D Model disappears.
I am using the below lines of code for 3D Model display.

typedef igstk::ImageSpatialObjectVolumeRepresentation<igstk::CTImageSpatialObject>VolumeRepresentationType;
VolumeRepresentationType::Pointer   m_ImageRepresentation3D;
m_ImageRepresentation3D = VolumeRepresentationType::New();
m_ImageRepresentation3D->RequestSetImageSpatialObject(m_ImageSpatialObject);

Is there anything I could do to solve this problem.
Please suggest.

Thanking in advance,
Ashwath.

Hi,

We found a workaround probably related to your problem :

igstkCrossHairObjectRepresentation.cxx, line 302

  lineMapperX->SetResolveCoincidentTopologyPolygonOffsetParameters(0.5,0.5);

This solves the reslice issue we encountered a few months ago (http://www.cmake.org/pipermail/igstk-users/2011-March/001081.html).

I hope this will help !
Best regards,

Vincent

Hi All,

Is there a problem with igstk::CrossHairObjectRepresentation
class in IGSTK4.2 ad 4.4 because I am facing some display problems because of that.

I remove the cross hairs from the view by using the below codes:

m_CrossHair->RequestDetachFromParent();
m_view2DAxial->RequestRemoveObject(m_AxialCrossHairRepresentation);

And try to draw a small ellipse at clicked point on the Axial view.
But it appears on some other slice and not on the current slice.

Has anybody faced such problems before.

I found at below link about the cross hair related display problems in IGSTK 4.2 and 4.4.

http://www.cmake.org/pipermail/igstk-users/2011-March/001081.html

Is my problem because of the above  issue in crosshair related classes  in IGSTK.

Please suggest me something on this.

Thanking in advance,
Ashwath.
