This is how the viewer will look like. The image list is on the left side, while the viewer is on the right. A typical iPad split view in other words. The viewer is divided into four subviews, which will contain a coronal, sagittal, axial, and a 3D view.
Only the 3D view is implemented so far, but this is the most complicated view on the other side, so I'm happy that I've finished that part. The iPad is really fast and there's no problem doing volume rendering in real time on the device. You just slide the finger on top of the view to rotate the brain.
