DensityMap * binarize(DensityMap *orig_map, float threshold, bool reverse=false)
Return a map with 0 for all voxels below the threshold and 1 for those above.
virtual void resample()
Resample beads on an EM grid.
#define IMP_REF_COUNTED_DESTRUCTOR(Name)
Set up destructor for a ref counted object.
An approximation of the exponential function.
Class for sampling a density map from particles.
The class represents a molecule as shells of distance from the surface.
