Dual Contouring solves these problems, and is more extensible to boot. The trade off is we need to know even more information about f(x), the function determining … See more The gradientof a function f is a measure of how quickly the value of f changes at a given point when moving in any given direction. It’s normally given as pair of numbers for every … See more The 2d and 3d cases aren’t really that different. A cell is now a cube, not a square. And we are outputting faces, not edges. But that’s it. The routine for picking a single point per cell is the same. And we still find edges with a … See more So far, we’ve just got the same sort of stepped look that Marching Cubes had. We need to add some adaptivity. For Marching Cubes, we chose where along the edge put a vertex. Now we have a free choice of anywhere … See more WebJun 28, 2011 · @ПетърПетров I am no expert on this, but since Dual Contouring focuses on rendering isosurfaces (surfaces of the form f ( x, y, z) = 0) That you must have an algorithm that computes f ( x, y, z) for all ( x, y, z) in the domain, and you must have an algorithm that computes the derivative of f ( x, y, z) at every ( x, y, z) in the domain.
