Este trabalho descreve uma nova visão sobre um dos algoritmos mais importantes da Computação Gráfica, o algoritmo para a poligonização de isosuperfícies Marching Cubes (MC). Esta visão permite o estudo das situações onde são gerados triân

In this paper we present a computational framework for semi-automated assessment of skeletal age based on a multi-scale image analysis approach. Through 2D digital X-ray images of the left hand, maturity indicators are searched by means of a two-step

Marching Cubes is a popular choice for isosurface extraction from regular grids due to its simplicity, robustness, and efficiency. One of the key shortcomings of this approach is the quality of the resulting meshes, which tend to have many poorly sha

Marching Cubes is the most popular isosurface extraction algorithm due to its simplicity, efficiency and robustness. It has been widely studied, improved, and extended. While much early work was concerned with efficiency and correctness issues, latel
