2D Layout for 3D Design

Design Computing and Cognition '08, 2008

This paper describes a research project which aims at studying the ergonomic and cognitive value of EsQUIsE, a freehand design environment for architects. This sketch-based modeling software is implemented on a Tablet PC. The EsQUIsE software provides architects with the possibility to generate automatically 3D views from the freehand drawings. The first part of the paper deals with the usability of such a digital environment for sketching, and especially the use of the drawing areas. The second part of the paper is dedicated to the analysis of how 3D views are generated and used for exploring alternative solutions. Although in interviews architects rate 3D highly, in fact they do not produce a large volume of 3D sketches. Issues about visual and spatial reasoning in design are thus highlighted. Finally, the benefit of such a tool for creativity is questioned.

To start a design process with plan and section in 2D environment (pen and paper) will exclude thousands of possibilities, which the designer will never be able to consider them. The 2D designer will never touch upon the rich world of complexity.. Starting the design from higher dimension is the solution to get rid of old conventional designing methods. Adding extra dimension to the "starting point" is applying CAD (computer aided architectural design) software not to extrude the 2D lines, but thinking from a higher dimension. Now thinking out of the box from out of the box becomes possible. To prove the hypothesis, authors decided to conduct an experiment and asked a group of architecture students to design a same architectural task with different dimensions. First the conventional pen and paper in 2D and the second time applying 3D environment interface of their own choice for the same task. The jury of experts concluded that students were more creative when they chose a 3D interface (higher dimension).

: This thesis examines interactive techniques for viewing a 3-D building model in a walkthrough fashion and for placing 3-D piping into a 3-D building model. The focus of research is software implementation using the C programming language and the IRIS Graphics Library on the Silicon Graphics Inc. IRIS Turbo 2400 interactive graphics system. The first part of the research is concerned with drawing, viewing a 3-D building model, and examining interactive techniques required for building walkthrough mechanims. The second part is concerned with the development of techniques necessary to allow the placement of 3-D piping into a 3-D building model using 2-D graphics display and a mouse device. The algorithms and implementation of these techniques are presented.

Technical drawings are the language engineers and architects use to communicate their ideas and designs to journeymen. It is a language based on lines and s:mbols that have specific meanings. Journeymen must possess the sldll to interpret these symbols and l i e s , so that they may install and maintain piping systems.

There are several kinds of layout problems, most of them concerning the allocation of a set of planar objects over a delimited planar area. There are several forms of representation of such problems, depending on their application. In order to treat these layout problems in a unified way, we propose an object-oriented approach that decomposes the problems in generic entities needed by a problem processing engine, the Layout Planner, to form a problem solver instance. This paper concerns the description of a tool for development of decision support systems for layout planning, where the entities are mapped into objects that own a dynamic behaviour. The user describes his/her problem instance in a graphical way using visualisation forms of the objects. A fertile application field of such DSS is in CIM activities such as machine layout and cutting. First, we identify models and approaches for layout problems and present an architecture for the DSS generator and then discuss a case study of the leather cutting problem.

In this paper, we propose innovative system in order to assist the user in a 3D objects layout context. Through a combination between virtual reality (VR) and constraint programming (CP) technique, user's 3D interaction and manipulation will be translated to incoming queries of a constraints solver which propagate constraints and generate a new possible solution. The computed solution is transmitted, as new positions of 3D objects, to virtual environment (VE) which reconfigures itself. We focus in this paper on the architecture of our system and we describe the implementation of several constraints and some first results.

Geometric design (GD), also known as geometric modelling, is a branch of computational geometry. It deals with the construction and representation of free-form curves, surfaces, or volumes. [1] Core problems are curve and surface modelling and representation. GD studies especially the construction and manipulation of curves and surfaces given by a set of points using polynomial, rational, piecewise polynomial, or piecewise rational methods. The most important instruments here are parametric curves and parametric surfaces, such as Bezier curves, spline curves and surfaces. An important non-parametric approach is the level set method.

Vilnius Gediminas Technical University 11 Saulėtekio st., LT2040 Vilnius, Lithuania email: [email protected] Abstract. Development of the engineering graphics performance technologies raises new questions concerning the methodology of the solution of this discipline’s tasks. The article presents peculiarities of computer-aided detection of a simple section view projections based on a 3D model using AutoCAD and SolidWorks computer systems. Moreover, differences between results and standard requirements for sectional views and ways in which more accurate results can be obtained are discussed. Author shows inaccuracies of details sectional views created automatically and analyses the ways of correcting the drawing manually.

2.2. 1 Definitions (i) The index rule: When an index appears once in a formula, the formula is valid for every value of that index.(ii) The summation rule: When an index appears twice in a term, it is assumed that a summation is taken place over all possible values of that index.(iii) The maximim rule: An index can not be used more than twice in the same term.

Computer-aided 3D ICs layout design requires efficient search of large and discontinuous spaces and no deterministic algorithms are able to perform such a task. The paper presents a new framework for visual kind of intelligent layout design. In the proposed approach a shape grammar generates possible design solutions while intelligent algorithms control the direction of the solution space exploration. Although the method is not limited to a particular design assignment, the paper focuses on a 3D ICs layout problem to demonstrate its potential.
