Drawing Tools

Historical information on several drawing tools such as the pencil, chalk and charcoal. The development of the printing press in the 15th century led to an increase in the availability of paper and the use of chalk and other drawing tools. This handout also describes what each tool was used for.https://source.sheridancollege.ca/wightman_collection_art_design/1003/thumbnail.jp

Compensation of deep drawing tools for springback and tool-deformation

Manual tool reworking is one of the most time-consuming stages in the\ud preparation of a deep drawing process. Finite Elements (FE) analyses are now widely\ud applied to test the feasibility of the forming process, and with the increasing accuracy of the\ud results, even the springback of a blank can be predicted. In this paper, the results of an FE\ud analysis are used to carry out tool compensation for both springback and tool/press\ud deformations. Especially when high-strength steels are used, or when large body panels are\ud produced, tool compensation in the digital domain helps to reduce work and save time in the\ud press workshop. A successful compensation depends on accurate and efficient FE-prediction,\ud as well as a flexible and process-oriented compensation algorithm. This paper is divided in\ud two sections. The first section deals with efficient modeling of tool/press deformations, but\ud does not discuss compensation. The second section is focused on springback, but here the\ud focus is on the compensation algorithm instead of the springback phenomenon itself

Can Digital Drawing Tools Significantly Develop Children’s Artistic Ability and Creative Activity?

This study aims to investigate how the new digital art tools can significantly improve children‟s artistic ability and creative activity. This particular research tested 16 students aged 9-10 years old in art classes, with the intention of presenting a model for the development and measurement of technological creativity. It uses a modified TAM technology acceptance model to assess the usefulness of digital art tools. The children were provided with appropriate subjects and techniques to improve their performance with the tools, and the relationship between art, technology and creativity was explored. The results of the project show a general improvement in pupils‟ artistic ability and inventiveness through the development of their technological skills, as well as greater ability to express themselves visually

Drawing Tools

I am from a small town in Northern Minnesota where my father runs an aggregate production business. I grew up surrounded by the heavy equipment used to move and crush gravel. My earliest memories are of seeing this machinery and being fascinated by its size, power, and sound. My work borrows the imagery and scale of these machines to make abstract forms and tools. Through making these objects I arrive at some kind of nonsensical use for them. I will create a scene, or job site where the object is used to mark another material. The tool will be used until some kind of limit is met. I will either operate the tool until I physically can't do it, or the tool becomes stuck or broken

A Research on Landscape Architecture Student Use of Traditional and Computer-Aided Drawing Tools

Objective: This study includes a survey study on the effectiveness of the landscape design process of traditional and computer aided drawing tools by landscape architecture students. The research hypothesis, the traditional drawing tools in the process of landscape design, continue to be used in certain parts of the process. However, the computer aided drawing tools are currently used more effectively and more frequently. Materials and Methods: In order to test this hypothesis, a questionnaire was applied to the students of the department of landscape architecture. In order to reveal the effectiveness of drawing tools in the design process, a total of 111 landscape architecture students took part in a survey which included 68 questions. As a result of the survey, students' attitudes towards drawing tools were revealed. The questionnaire consists of 21 multiple-choice question, 5 open-ended questions, and 42 questions on the ranking positive sentences by degrees. The data was evaluated using SPSS program (version 15.0). Man-Whitney U and Wilcoxon tests were applied in order to compare the two drawing tools according to the data of the 5th and 6th chapters and to reveal the differences in preference to gender discrimination. Results: The survey participants consisted of 72 females (64.9%) and 39 males (35.1%) students. The majority of the respondents with 53 people were from the third year, 5th semester students. Determining in which stages of the design process, which of the drawing tools they prefer to use. As a result of the survey, it was found that 91% of the students were more positive about computer aided drawing tools. Conclusion: According to the results of the survey, it is certain that the computer aided drawing tools are considered more favourable. However, 92,8% think that traditional drawing tools and computer aided drawing tools can be used together during the student design process

A graph rewriting programming language for graph drawing

This paper describes Grrr, a prototype visual graph drawing tool. Previously there were no visual languages for programming graph drawing algorithms despite the inherently visual nature of the process. The languages which gave a diagrammatic view of graphs were not computationally complete and so could not be used to implement complex graph drawing algorithms. Hence current graph drawing tools are all text based. Recent developments in graph rewriting systems have produced computationally complete languages which give a visual view of graphs both whilst programming and during execution. Grrr, based on the Spider system, is a general purpose graph rewriting programming language which has now been extended in order to demonstrate the feasibility of visual graph drawing

A Flexible and Fast Event-Driven Simulator for wireless MAC protocols

Many multiple-access (MAC) protocols have been or are being proposed for wireless networks. As most of these multiple-access protocols are designed for specific applications (such as telephony) and analyzed accordingly, the analysis results can not always be adapted to situations where each user has a different behavior. Wireless MAC protocols for data communication are not straightforward to analyse. To quickly make a reliable judgement of the usability of a MAC protocol for specific situations, we designed a simulator that makes it simple to implement the protocol and test it in different configurations and with differently behaving users. Our simulator generates a large amount of quantitative performance information that can be processed with standard graph drawing tools and an integrated trace analyze

Fast Spherical Drawing of Triangulations: An Experimental Study of Graph Drawing Tools

We consider the problem of computing a spherical crossing-free geodesic drawing of a planar graph: this problem, as well as the closely related spherical parameterization problem, has attracted a lot of attention in the last two decades both in theory and in practice, motivated by a number of applications ranging from texture mapping to mesh remeshing and morphing. Our main concern is to design and implement a linear time algorithm for the computation of spherical drawings provided with theoretical guarantees. While not being aesthetically pleasing, our method is extremely fast and can be used as initial placer for spherical iterative methods and spring embedders. We provide experimental comparison with initial placers based on planar Tutte parameterization. Finally we explore the use of spherical drawings as initial layouts for (Euclidean) spring embedders: experimental evidence shows that this greatly helps to untangle the layout and to reach better local minima
