The generation of 3D solid objects, and more generally solid geometric modelling, is very important in Computer Aided Design (CAD). This paper presents a simple but effective algorithm for automated display of perspective views of Constructive Solid Geometry (CSG) scene models. This algorithm can be implemented as a module in such a way that it is easily integrated, without any modification, to...

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 civil construction. In order to obtain models, which would be able to visually simulate the construction process of two types of construction work, the research turned to the techniques of geometric modelling and virtual reality. The ap...

This paper presents a parametric stiffness analysis of the Orthoglide, a 3-DOF translational Parallel Kinematic Machine. First, a compliant modeling of the Orthoglide is conducted based on an existing method. Then stiffness matrix is symbolically computed. This allows one to easily study the influence of the geometric design parameters on the matrix elements. Critical links are displayed. Cutti...

Mosque is an important place for all Muslims around the world as it a to perform religious activities. However, design layout of some mosques nowadays not suitable user mostly in rural area where most older. This due lack any standards and guidelines, are being designed built per personal wisdom architects, financiers individuals or groups responsible its execution. Hence, this paper has identi...
