Campanus houses, Gauquelin sectors, parans, and astrocartography have some elements of 3 D astrology.
Campanus houses are effectively a 3D version of Equal houses.
3D aspects are similar to standard and parallel aspects unified and combined into one.
Note: in Mundo rather than tropical for astrocartography, as used by Jim Lewis.
Porphyry houses in all four models (2D along ecliptic, 3D along prime vertical, 3D along local horizon, and 3D along celestial equator), see: http://www.astrolog.org/astrolog/pic/sphere3d.gif
