| ABBREVIATIONS: h-dial (horizontal), v-dial (vertical), m-dial (meridian dial), p-dial (polar dial), q-dial (equatorial), etc. The parts of a sundial are here..... |
| WHAT KIND OF SUNDIAL TO BUILD Before you build a sundial, decide what kind is best. Latitudes between the equator and about 15 degrees N or S would benefit from an equatorial (q) or polar (p) dial more than from a horizontal (h) dial design. On the equator a horizontal (h-dial) is a polar dial so use a p-dial design. At the poles, an h-dial is an equatorial dial, so use a q-dial design ~ run the DeltaCAD h-dial at low and high latitudes for fun, they approach the polar dial and q-dial. |
