Splet06. okt. 2024 · In computer graphics, marching squares is an algorithm that generates contours for a two-dimensional scalar field (rectangular array of individual numerical values). A similar method can be used to contour 2D triangle meshes . The contours can be of two kinds: Isolines – lines following a single data level, or isovalue. Marching squares takes a similar approach to the 3D marching cubes algorithm: Process each cell in the grid independently. Calculate a cell index using comparisons of the contour level (s) with the data values at the cell corners. Use a pre-built lookup table, keyed on the cell index, to describe ... Prikaži več In computer graphics, marching squares is an algorithm that generates contours for a two-dimensional scalar field (rectangular array of individual numerical values). A similar method can be used to contour 2D triangle meshes Prikaži več The same basic algorithm can be applied to triangular meshes, which consist of connected triangles with data assigned to the vertices. For … Prikaži več The algorithm is embarrassingly parallel, because all cells are processed independently. It is easy to write a parallel algorithm Prikaži več Here are the steps of the algorithm: Apply a threshold to the 2D field to make a binary image containing: • 1 where the data value is above the isovalue Prikaži več The data space for the Marching Squares algorithm is 2D, because the vertices assigned a data value are connected to their neighbors in a 2D topological grid, but the spatial … Prikaži več • Marching Square Matlab algorithm – An easy to understand open-source marching square algorithm. • implementation in Java • Marching Squares code in Java.
