dot_color (color, default -1) controls the color of the dot representation. By default, dots assume the color of the associated atom.
dot_density (integer, default: 2) controls the density of dots taken from the surface of a sphere.
dot_hydrogens (boolean, default: on) controls whether or not dots are drawn on hydrogen atoms.
dot_lighting (boolean, default: on) controls whether or not dots are lit based on their associated surface normals. The setting has no effect when ray tracing.
dot_normals (boolean, default: on) controls whether or not dots are drawn with normals. This achieves essentially the same effect as dot_lighting, and it too has no effect when ray tracing.
dot_radius (float, default: 0.0) if greater than zero, controls the radius of dots. Otherwise, the dot radius is computed from dot_width based on the pixel size of the current viewport.
dot_solvent (boolean, default: off) controls whether we generate dots for the atomic or solvent accessible surface.
dot_width (float, default: 2.0) controls the dot width in viewport pixels.
