Abstract
The paper describes methods for graphical reconstruction from a single image acquired with a completely uncalibrated camera or even from lithography. The proposed method involves a multimodal approach, such as: digital photogrammetry, 3D photo modelling, CAD design, parameterization, VRML programming. In addition, we propose a visualization method based on Virtual Reality technology, using an immersive CAVE like 3D system. The 3D reconstructed model offers the possibility of details visualization, quickly change the geometry, textures, environment, viewpoint and size and can also be easily accessed using Internet browsers and a VRML client plug-in. As an example and a practical application of the presented method, there was completed the virtual 3D reconstruction of the demolished church Sf. Vineri from Bucharest. The sources of virtual reconstruction were archival, architectural and contemporary historical information.
