Un lieu qui parle : la modélisation architecturale 3D vers une quatrième dimension

The project to produce a 3D laser scan of the Chapelle des Ursulines (Ursulines’ shrine) in Quebec City and to create the experience of an immersive virtual visit, illustrates the new types of relations to space afforded by information technologies. The Panoscope (Courchesne 2000) equipped with an omnidirectional controller offers an alternative experience of the shrine that opens new roads for the interpretation of the formal and symbolic dimensions associated with such spaces. If the virtual model will never replace the original physical shrine, it nevertheless offers an experience enriched by multiple layers of information. Furthermore, it allows for the live interaction between remote visitors and experts into a dynamic dialogue about the various aspects and dimensions of this historical site. Such a project finally contributes the ongoing discussion about the new models for mixed reality Milgram et Kishino (1994) and their value in the interpretation of patrimonial heritage.
