This document discusses the potential use of stereo 3D applications for heritage disaster management. It provides examples of historic 3D photography from the 19th century and describes how 3D models can now be superimposed on photographs for reconstruction purposes using augmented reality. Programming examples are given for an Adobe Director application that generates a 3D geometric model and particles. The document concludes stereo images are not fully utilized and augmented reality could help translate paper reconstructions into interactive computer applications.
