A study of data reduction for intuitive AR interface

Augmented Reality is expected as an intuitive user interface in wearable computer devices. However, the devices like iPhone have the limitation of the computing resources. AR requires a drastic data reduction of 3D graphics models in order to work at interactive speed on such devices. As the data reduction method, I have proposed 3D model rebuilding from the rendered images. In this paper, I introduce two cases I have tried. The first one is the way to rebuild the 3D model from only three images from orthogonal three directions. The second one is the way to add Z buffer information to it. I have captured the Z buffer information through OpenGL capture technique. It allows us to get it from any OpenGL based graphics software. As the result from some tests, we have understood that the first one can be applied to only the limited contents, but the second one can be applied to the wider range of contents.
