Paper Abstract:
|
The three-dimensional geometric models used to present architectural and engineering work, show only the final form,
which does not allow progress in constructions to be observed. But, the visual simulation of the construction process of a
building need models which are able to produce dynamic changes to their geometry. This paper reports how techniques
of geometric modelling and virtual reality were used to obtain models that could show their physical evolution over time
and which would be able to simulate construction processes visually. Two types of work, concerning the construction of a
cavity wall and a bridge, were developed as virtual models for educational purposes. These models make it possible to
view the physical evolution of the work, to follow the planned construction sequence, to visualize details of the form of
every component of each work and to support the study of the type and method of operation of the equipment necessary
in the construction process. Using virtual reality technology allows the teacher/student to manipulate, interactively, the
physical evolution of the work and the construction activities inherent in its progression, namely the length of time each
component will be exhibited and the point of view of observation. These models have been used to distinct advantage as
educational aids in first-degree courses in Civil Engineering. The use of virtual reality techniques in the development of
educational applications brings new perspectives to the teaching of subjects related to the field of construction. |
