In this work, we developed a software tool for the simplified, automated definition and viewing of loci in plane, an essential task design, engineering architectural fields. The process was started by identifying most salient geometric domain (i.e., tangents). A approach followed to deal with curves from relative positions two circles or circle point. algorithms used can be easily implemented c...

Computer generated images and animations are getting more and more common. They are used in many different contexts such as movies, mobiles, medical visualization, architectural visualization and CAD. Advanced ways of describing surface and light source properties are important to ensure that artists are able to create realistic and stylish looking images. Even when using advanced rendering alg...

Web-enabling technologies represent the next generation of design environments to design and manufacture complex systems, such as them characterizing contract furniture. In the context of web applications to facilitate and support teamwork in collaborative product development, the paper presents a CAD-based infrastructure for the 3D visualization of co-designed solutions, the on-line customizat...

This paper examines the need to provide a common interface to expert systems, simulation tools and CAD systems for architectural design. We observe that a large amount of information is duplicated in describing buildings to several different tools. We describe a frame based representation for building designs, and an interfacing mechanism to move information between various tools. We also exami...

This paper presents a new 3D scene analysis system that automatically reconstructs the 3D model of real-world scenes from multiple range images acquired by a laser range finder on board of a mobile robot. The reconstruction is achieved through an integrated procedure including range data acquisition, geometrical feature extraction, planning the next view, registration and integration of multipl...

This paper shows how software architecture and data modeling techniques are used as core attributes of a CAD tool suite. We discuss the issues that have influenced Nike’s architectural direction, such as technology trends, processor architecture trends, and computing platform trends. We identify some of the major drawbacks of existing tool suites and show how Nike architecture addresses these. ...

In this work we address the question of how to exploit typical architectural structures to improve accuracy for CAD modeling of built environments from 3D data. In doing so we have examined the applicability of the GENOCOP III algorithm to the model fitting. The algorithm uses explicit domain knowledge, specifically geometric constraints in the form of parameterized surface models and an Euclid...

Building Information Modeling (BIM) has made a considerable impact on the construction industry and the way in which building design information can be accessed and interrogated. This impact is now being seen in the Schools of Architecture in the UK. Academia is beginning to see the feasibility and benefits of converting to such a new technology; will this inevitably start to filter into teachi...
