    Marching Edges: A Method for lsosurface Extraction
    (The Eurographics Association, 2022) Velasco, Francisco; Torres, Juan Carlos; Cano, Pedro; Xavier Pueyo; Manuel Próspero dos Santos; Luiz Velho
    Volumetric data can be represented as a rectilinear structured grid and can be displayed by the rendering of an isosurface that is built from the grid and defining a threshold value. The know marching cubes method builds the isosurface cell by cell. However, from a set of cells that comply with some conditions, a bigger cell can be built. ln these cases, the volume is represented by a set of cells of different size. Then, the isosurface built by marching cubes will have holes on the borders between cells of different size. ln this paper, we show a new method, called marching edges, to build the isosurface edge by edge, that generates a hole-free isosurface.
