You can add animations to move the camera’s position, or its zoom say, in exactly the same way and create a “fly past” but to make it look impressive you will need more than a single cube and this is the start of a very big project…

If you would like the code for this project then register and click on CodeBin or you can copy and paste the listing below.

Listing

The complete program is (omitting the usual using statements):

using System.Windows.Media.Media3D;
using System.Windows.Media.Animation;namespace Cube1

 /// </summary>
