There are 3D point clouds and 3D models. Download respective viewer (see below). To choose a project click on thumbnails bar. To open 3D content click on a big gallery picture. Be patient: it takes time for 3D to download in a new window.

To view a sample point cloud generated with My3DScanner in true 3D you need to download and install free 3D viewer.

To view complete polygonal model in 3D make sure you have Adobe Reader 8.0 or newer installed.
