Click on any of the links to go to the 3D viewer.
In the viewer there is a reference image on the left which has been used to produce the 3D reconstruction on the right.
Click on either of the parts or use the left/right arrow keys to focus on them.
In the 3D canvas you change camera position by moving mouse on the canvas and use the mouse scroll or up/down arrow keys to zoom.
If there is a sequence of 3D images you can (with the page in focus (click on it)) pause it by using space.
