         * Geometry instancing allows one {@link Geometry} object to be positions in several
         * different locations and colored uniquely.  For example, one {@link BoxGeometry} can
         * be instanced several times, each with a different <code>modelMatrix</code> to change
         * its position, rotation, and scale.

         * @param {Geometry} options.geometry The geometry to instance.
         * @param {Matrix4} [options.modelMatrix=Matrix4.IDENTITY] The model matrix that transforms to transform the geometry from model to world coordinates.
         * @param {Object} [options.id] A user-defined object to return when the instance is picked with {@link Scene#pick} or get/set per-instance attributes with {@link Primitive#getGeometryInstanceAttributes}.
