Contribute to Kitware/VTK development by creating an account on GitHub. So, in most cases SetSelectedColor method must be used to change markups node color. Reslices a volume along a new set of axes. An Update() is called on the transform to ensure that the matrix is up-to-date when you get it. If we would use the origin (position of the (center of) the first voxel) as a corner and display this point, it would seem to be not at the corner Hi Sebastien, vtkTransform performs rotations in the ZXY order.
