List of all members.

Public Methods
	VolMapCreateDensity (VMDApp *app, AtomSel *sel, float res, float *the_weight, float the_radscale)
Protected Methods
int	compute_init ()
	Creates a map of the weighted atomic density at each gridpoint. This is done by replacing each atom in the selection with a normalized gaussian distribution of width (standard deviation) equal to its atomic radius. The gaussian distribution for each atom is then weighted using an optional weight, and defaults to a weight of one (i.e, the number density). The various gaussians are then additively distributed on a grid. More...

int VolMapCreateDensity::compute_init (    )  [protected, virtual]

Creates a map of the weighted atomic density at each gridpoint. This is done by replacing each atom in the selection with a normalized gaussian distribution of width (standard deviation) equal to its atomic radius. The gaussian distribution for each atom is then weighted using an optional weight, and defaults to a weight of one (i.e, the number density). The various gaussians are then additively distributed on a grid. Reimplemented from VolMapCreate. Definition at line 530 of file VolMapCreate.C.
