Three-dimensional modeling connects several fields of knowledge, both basic and applied. 3D models are relevant in educa-tional research because the manipulation of 3D objects favors students' acquisition of spatial vision, but in the Geosciences, there are few didactic publications in Portuguese on the subject. The authors develop an educational research project to produce three-dimensional models of didactic examples of sedimentary basins: the Paraná Basin (Silurian-Upper Cretaceous), the Tau-baté and the São Paulo basins (Neogene). 3D-compatible files will be produced to compose didactic and display material, from maps and geological-structural profiles of certain regional stratigraphic levels of each basin. The research challenges are: (a) to obtain an overview of the available resources for 3D modeling; (b) to evaluate their potential, characteristics, advantages and limitations for applications in Geology and Geosciences; (c) to create computational models of the basins; (d) to produce at least one physical model based on one of the computational models of each basin. The resources will subsidize training work-shops for in-service teachers, technical-scientific articles and Internet pages.
A modelagem tridimensional tem sido objeto de pesquisas em vários campos do conhecimento, tanto básicos como aplicados. No campo das Geociências, as possibilidades ilimitadas de aplicação desafiam a imaginação e a criatividade dos pesquisadores. Ao mesmo tempo, oferecem grande desafio educacional, porque proporcionam a professores e estudantes o acesso a novas técnicas de representação capazes de estimular o desenvolvimento de visão espacial. Este projeto de modelagem 3D focaliza a bacia sedimentar de São Paulo, cujas informações de subsuperfície achamse em volume suficiente e adequado para produção de arquivos compatíveis com impressão 3D. O objetivo é compor material didático e de exposição, dividido em duas partes: o arcabouço da bacia (embasamento) e o preenchimento sedimentar. Os dados primários são mapas e perfis geológicos do pacote estratigráfico regional. A principal dificuldade enfrentada na pesquisa foi criar o primeiro modelo em ambientes e programas computacionais cujas licenças estejam disponíveis na Universidade. Essa etapa é indispensável para imprimir o modelo em 3D.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
