ARIAS-NARANJO, Gilberto et al. Efficient management of digital elevation models for 3D visualization using multicore processing. Rev cuba cienc informat [online]. 2014, vol.8, suppl.1, pp.14-28. ISSN 2227-1899.

In this paper is described a model for efficient visualization of terrain surfaces in three dimensions, which exploits the computational potential of today multi-core processors. A logical division of the terrain in tiles is performed, those tiles are represented using restricted quadtrees. The graphics load is controlled by an adaptive triangulation surface and taking advantage of different levels of detail. The scene being viewed is dynamically managed, keeping in memory only the data associated with those tiles that are being viewed. Those tiles that are not displayed are stored in external memory and managed using a data structure that allows efficient access to the data.

Palavras-chave : 3D visualization; multi-core; multi-resolution triangulation; restricted quadtree.
