Reconstruction of 3D Virtual buildings from 2D architectural floor plans

Abstract

Visualizing architectural designs with the aid of Virtual Reality (VR) technology is becoming a common task among architects, design engineers, contractors and customers due to a more realistic resemblance to the real look of the final constructions. In order to preview virtual buildings, one needs to reconstruct a VR model from the two-dimensional architectural drawings. In the conventional approach, a large amount of manual tasks are necessary while using some common 3D authoring tools avaliable in the market. This gives us the incentive to examine the process of modelling and reconstruction of 2D designs for use in practical applications. In this paper, we identify the main tasks in the conventional reconstruction process and give a semi-automated solution that aids in the process of extrusion and modelling of large building complexes. © 1998 ACM.
