- Anamorfoses e outras tecnologias imersivas no contexto da educação artísticaPublication . Flores, Manuel; Araújo, António; Figueiredo, MauroApresentamos uma proposta de investigação na área da média-arte digital onde se pretende combinar os princípios da anamorfose com as novas tecnologias baseadas na realidade aumentada. Esta perspetiva tem subjacente a ideia de que é possível relacionar a anamorfose cónica com as projeções realizadas em Realidade Aumentada. No âmbito desta investigação propõe-se uma abordagem ao estudo da perspetiva centrada nos contributos de Dürer e nos conceitos fundamentais da construção de anamorfoses. Pretende-se refletir sobre as possibilidades desta abordagem metodológica e analisar os seus contributos no desenvolvimento da capacidade de visualização espacial dos alunos do 3º ciclo do ensino básico e, desta forma, facilitar a compreensão dos conceitos relativos ao ensino da geometria.
- Cardboarding mixed reality with Dürer MachinesPublication . Araújo, AntónioMixed reality is a direct application of 15 to 17th century principles of anamorphosis. The inherent physicality of anamorphosis, materialized through the Dürer perspective machine makes it an excellent teaching tool for students of digital art interested in mixed reality, whose initial core competencies may be extremely varied. The needs of these students are not met by the mere ephemera of learning how to use a particular piece of software; such knowledge is both transient and limiting of imaginative possibilities. We discuss a didactic strategy of cardboarding, i.e., a process of deliberate rudimentarization, to expose the inner workings of opaque chains of digital processes, to both clarify the elements of these chains and create loci for artistic intervention at their points of connection.
- Guidelines for drawing immersive panoramas in equirectangular perspectivePublication . Araújo, AntónioVirtual Reality (VR) Panoramas work by interactively creating immersive anamorphoses from spherical perspectives. These panoramas are usually photographic but a growing number of artists are making hand-drawn equirectangular perspectives in order to visualize them as VR panoramas. This is a practice with both artistic and didactic interest. However, these drawings are usually done by trial-and-error, with ad-hoc measurements and interpolation of precomputed grids, a process with considerable limitations.We develop in this work the analytic tools for plotting great circles, straight line images and their vanishing points, and then provide guidelines for achieving these constructions in good approximation without computer calculations, through descriptive geometry diagrams that can be executed using only ruler, compass, and protractor.
