Whar are values returned by measure.marching_cubes
Hello, I'm not familiar with scikitimage. I only want to use the function `measure.marching_cubes`, but I cannot figure out what really represent the values returned by it. `help(measure.marching_cubes)` says: *values : (V, ) array* *Gives a measure for the maximum value of the data in the local region near each vertex. This can be used by visualization tools to apply a colormap to the mesh.* What is data here (this term is too general)? I saw that values.shape[0] is the same as vertices.shape[0]. Hence each value is associated to a vertex. How is it assigned to a vertex? How are these values related to the volume or to the equation F(x,y,z)=0? (I want to extract a triangulation of an implicit surface having this equation). A second question is related to the coordinates of vertices. When I plot the trisurf defined by `vertices` and `faces` I notice that the x, y and zrange illustrated by tick values is different from the real values. More precisely: if my surface has zmin=1 and zmax=2, on zaxis this range is [5,11]. Is there a transformation that maps the vertices coordinates, as they are returned by `measure.marching_cubes` to real coordinates on my surface? Thanks, Eve
