Beata Stahre


Country of Birth : Sweden
Resident : Göteborg, Sweden
Title : Architect and PhD
 
Statement:
I am an architect with a PhD in spatial architectural visualization, focusing especially on colour appearance in digital modeling. In February 2009 I defended my thesis "Defining Reality in Virtual Reality: Exploring Visual Appearance and Spatial Experience Focusing on Colour".

My thesis project has dealt with the difficulties of translating reality into digital counterparts, focusing on visual appearance, particularly colour; and spatial experience. The goal has been to research how different aspects of a VE, especially colour and light affect the spatial experience. This to contribute to a better understanding of the prerequisites for visualizing believable spatial models in VR. The main aims have been 1) to identify problems and test solutions for simulating realistic spatial colour and light in VR; and 2) to develop knowledge of the spatial conditions in VR which are required to convey believable experiences; and to evaluate different ways of visualizing spatial experiences. The studies are conducted from an architectural perspective; i.e. the whole of the spatial settings has to be considered. The models are furthermore studied with an inside-perspective.


I am currently employed by the Dept of Architecture at Chalmers University of Technology and the Center of Visualization Göteborg (CVG).

Research interests:
Spatial experience and visual appearance in digital modeling and virtual environments; spatial colour and light appearance in reality and in digital modeling; visual expressions (others than photorealism) in the texturing/rendering of digital models.
