Gráfica Computacional e Modelação Geométrica

Objectives

Basic principles of a graphic system in a computactional environment, as a 3D way of visualization. Concept of 3D geometric modeling (surfaces and volumes) for parts and assemblies. Processes for object reconstruction from scans and images. Conversion of file formats for some engineering fields, analysis and prototype of components.

Syllabus

Applications of computer graphics and geometric modeling. Graphic elements and their representation: lines, text, raster images, color, coordinate systems. Equipment: input and output devices, interfaces. Graphic libraries and their standards. Program portability. Curves, Surfaces and Solids. Parametric representations. Computational implementations. Three-dimensional Visualization and Realism: Virtual camera, lighting, animation. 3D Control of Computer Objects: Types of images, formats, generation of 3D surfaces from 2D boundaries (sections). Mesh generation and treatment of volumes by closed surfaces. Mesh generation algorithms. Mesh quality and control. Applications to commercial programs in several areas. Geometric modeling of surfaces and volumes in CAD3D. Parametric models by features. Modeling of parts and assemblies. Examples of application to projects in biomedical applications.

Cross Competence Component

- Assertive and inovative mindset: criativity, strategic and problem solve oriented, decision making. - interpersonal skills: preparation and organization of the group work on the labs, discussion of the basic hypothesis and tests preparation and results. - intrapersonal skills: selfdiscipline, enthusiasm, perseverance, self motivation, use of informatics for calculations, modeling and documents presentation. - Literacy of information and media: search and retrieve information, analyse, filter and assess the contents. This skills are assessed on classes and final project.

Ethical Principles

All members of a group are responsible for the group’s work In any assessment, every student shall honestly disclose any help received and sources used. In an oral assessment, every student shall be able to present and answer questions about the entire assignment and solution.
