Analysis of images with 3D features is generally to be avoided (see Images appropriate for analysis). One of the biggest, and very immediate, obstacles in computer vision is the inability to extract 3d information from 2d images. My feeling is that by the time this problem is fully solved 3d images will become ubiquitous.
Sometimes information can be extracted though.
