Techniques for Aligning Objects in Drawing Programs
نویسندگان
چکیده
Object alignment is one of the basic operations in drawing programs. Current solutions provide mainly three ways for carrying out this operation: either by issuing an alignment command, or by using direct positioning with the help of gravity active points, or by making use of constraints. The first technique has limited functionality, and the other two may be mysterious for a novice. We describe here a new direct manipulation tool for alignment. We show that while direct manipulation helps to make the tool intuitive, it has through iterative design evolved into a tool that also offers functionality not found in current commercial products.

Objects Identification in Object-Oriented Software Development - A Taxonomy and Survey on Techniques
Analysis and design of object oriented is onemodern paradigms for developing a system. In this paradigm, there are several objects and each object plays some specific roles. Identifying objects (and classes) is one of the most important steps in the object-oriented paradigm. This paper makes a literature review over techniques to identify objects and then presents six taxonomies for them. The f...
متن کاملThe Effects of Observation Coaching on Children's Graphic Representations
Education programs have fostered advanced levels of graphic representation ability in young children but have not detailed the specific mechanisms responsible for the accelerated growth. Research suggests that between 6 and 8 years of age children begin to observe more carefully before drawing and that observation prompts aid children's development of graphic representations. This study experim...
متن کاملAdocs: a Drawing System for Generic Combinatorial Structures
Existing graph drawing systems imply the use of speciic algorithms for each kind of data structures. This paper provide a description of the Adocs program. The program is based on a generic description of the structures, and thus allows to draw structures of an innnite number of classes. It can be used in order to produce graphical output for Gaaa, an uniform random generator of combinatorial s...
متن کاملA hybrid approach based on numerical, statistical and intelligent techniques for optimization of tube drawing process to produced squared section from round tube
In the tube drawing process, there are a bunch of parameters which play key role in process performance. Thus, finding the optimized parameters is a controversial issue. Current study aimed to produce a squared section of round tube by tube sinking process. To simulate the process finite element method (FEM) was used. Then, to find a meaningful kinship between process input and output parameter...

In many cases it may be thought, corrosion products cover the unique characteristics of ancient metal objects that are desirable to display. While the scientific point of view, the corrosion products as well as metal substrates are important and maintain the original topography of metal that have been replaced. In technical studies of the historical metal objects, the dense layers of corrosion ...
