Class Avogadro::Rendering::SphereGeometry#

class Avogadro::Rendering::SphereGeometry : public Drawable#

The SphereGeometry class contains one or more spheres.

This Drawable is capable of storing the geometry for one or more spheres. A sphere is defined by a center point, a radius and a color. If the spheres are not a densely packed one-to-one mapping with the objects indices they can also optionally use an identifier that will point to some numeric ID for the purposes of picking.
