Abstract

The results of this research aim to describe the representation system made with immersive visualizations. The main goal is to transfer techniques that characterizes immersive models from raster images to models generated with vector images. This way is passed over the boundary that supposes the simple substitution of the elementary geometrical entity, point (or pixel), with the line. In order to do it, the transformations from bi-dimensional views to the immersive panoramic will be codified. It is proposed an advancement for the state of the art, connecting the studies with the descriptive geometry field, opening the cone of vision to the whole space that surrounds the observer. The work considers, as a departure point, previous studies about hybrid immersive models using both equirectangular and cubical projections. But, while for the equirectangular projection there is a complete bibliography for both intuitive (trail-error) and mathematical methods, for cubical projection instead, the procedures are just approximated, without a necessary theoretical and complete framework. The used method previews, as a mandatory passage, the development of geometrical formulations that will constitute the base for the mathematical ones. Announcing future steps, the content here presented in graphical terms, will look to be synthesized in an algorithm with digital graphics output, written ad-hoc, looking to propose a new advanced technique of representation.
Los resultados de esta investigación están destinados al estudio del complejo sistema de representación generado a través de imágenes inmersivas. El objetivo general es transferir las técnicas que caracterizan los modelos inmersivos generados con imágenes raster a modelos inmersivos generados a partir de dibujos vectoriales, sin limitarnos a una mera sustitución del ente geométrico elemental punto (o píxel) con la línea. Para ello, se codifican las transformaciones desde las vistas bidimensionales a la panorámica inmersiva. Se propone un avance del estado del arte, reconduciendo los estudios al ámbito de la geometría descriptiva, ampliando el cono de visión a los 360º del espacio que rodean al observador. El trabajo se vale de estudios anteriores sobre modelos híbridos inmersivos, la proyección equirectangular y la cúbica. El estado del arte que se asume como base de partida se caracteriza de una bibliografía completa para la equirectangular, sea con propuestas de métodos intuitivos como con métodos matemáticos mientras que para la proyección cúbica los procedimientos usados hasta hoy son solamente aproximados y desprovistos del necesario marco teórico completo. El método puesto en juego prevé, como pasaje obligado, el desarrollo formulaciones geométricas que servirán de base a formulaciones matemáticas. Anunciando pasos futuros, el contenido presentado en términos gráficos, buscará ser sintetizado en un algoritmo de gráfica digital escrito ad-hoc, para sentar las fundaciones de una nueva técnica avanzada de representación.
