In a method for visualization of information from first and second 3D datasets representing directional information of a subject, wherein some voxels are combined along their respective directional information into multiple fibers, a first item of anatomical information, visible from a first viewing position on a fiber, is determined from the first 3D dataset, and is projected onto a first projection surface at a display dependent on the first viewing position. Upon detected movement away from the first viewing position, a guided movement along the fiber is determined, which is restricted to movement along one fiber. A second viewing position is determined in the subject relative to the selected fiber dependent on the guided movement, and a second item of anatomical information is determined from the first 3D dataset, which is visible from the second viewing position, and is projected onto a second projection surface at the display.
