Heres a brief explanation of how the 4d view works:
First we project to 3D using  a 4D camera, here you can explore the projected scene using a normal 3D camera that works just like in 3D scene. Now lets look at the 4D camera. Its a spherical camera that always looks at center. By pressing q,e you can move the camera closer or farther away from the center, by using j,k,l,i,u,o you controls the angles of the spherical camera, changing where it looks.
