Hi Taylor,
could you please elaborate on what kind of data objects you have in your
scene? It sounds to us as if you are looking at your scene from the
other side so that the image is in front of your camera-representation.
Wouldn't it be sufficient to mirror the 2D image instead of rotating the
viewport around the objects?
If we didn't understand your problem correctly, please let us know.
Regards
Christoph

Hello MITK users,
I have a custom mapper Image2DVtkMapper3D for rendering 2D image as a
plane in a 3D scene with the vtkCamera placed precisely to mimic the
real-life camera that actually took the shot. This is working well,
but now I would like to take the viewport that I am rendering and
mirror it horizontally. I was able to get this to work with:
vtkSmartPointer<vtkTransform> mirrorTransform =
vtkSmartPointer<vtkTransform>::New();
mirrorTransform->RotateWXYZ(180, 0, 1, 0);
camera->SetUserTransform(mirrorTransform);
But that breaks layering of objects in front of my 2D image plane
object - they are now occluded by the 2D image plane. I was able work
around this by disabling updates to the depth buffer
in vtkOpenGLImageSliceMapper::Render with:
glDisable(GL_DEPTH_TEST);
But I know this is not the proper solution. So my question is what is
the proper MITK-ish solution here?
Thanks for any suggestions,
Taylor
