Virtual modelling through human vision sense

Abstract

The restoration/renovation of historic buildings has become an important facet of the construction industry, which can generate large economic benefits, drawn from the increased commercial value of these buildings and its surrounding area in terms of tourism and investment, apart from other non-priced benefits associated with user satisfaction. In this context, the rapid generation of tridimensional computer models from existent large objects like historic buildings can be particularly important either for building re-use, virtual museums or others patrimonial applications. This paper proposes a new biologically based computer tool, called Bio-CAD that mimics the human vision process. This system was specifically designed for the rapid and accurate generation of 3D computer models from existing large objects and can be integrated with other computer-based technologies. Two case studies were chosen to validate the system and to demonstrate its integration with rapid prototyping and Haptic CAD systems.

Structural Analysis and Design Optimization of a Selective Laser Sintering System

“…Selective laser sintering (SLS) is referred to as Rapid Prototyping (RP) technology, due to the time compression between product conceptualization to realization [1]. SLS is superior to other RP techniques because of the wide range of materials it can process.…”
