This paper presents an interactive graphics tool for the structural analysis of one-dimensional element models, such as trusses, frames, and grillages. The focus is on the creation of a graphical user interface for a previously developed analysis solver. This graphical interface is entirely implemented in the MATLAB environment and features intuitive resources so that modeling and verification of results become easy tasks for students and engineers. The management of mouse events and the adopted solutions to basic computer graphics issues that arise from interactive modeling in two-dimensional and three-dimensional canvases are discussed, including the strategies to pick objects in spatial coordinates and to identify crossing elements. The result is a new educational software that proved to be a very useful application in structural analysis and introductory computer graphics courses for engineering. The article also presents examples of using the software as an educational tool.

在 MATLAB 中使用计算机图形技术的结构分析软件的交互式用户界面

本文介绍了一种交互式图形工具,用于对桁架、框架和格栅等一维元​​素模型进行结构分析。重点是为以前开发的分析求解器创建图形用户界面。这个图形界面完全在 MATLAB 环境中实现,并具有直观的资源,因此对学生和工程师来说,建模和结果验证变得容易。讨论了鼠标事件的管理以及针对二维和三维画布中的交互式建模所产生的基本计算机图形问题所采用的解决方案,包括在空间坐标中选取对象和识别交叉元素的策略。结果是一个新的教育软件,被证明是结构分析和工程计算机图形学入门课程中非常有用的应用程序。本文还介绍了将该软件用作教育工具的示例。
