What do you think of the orientation of the house?

In a practical sense, the sitting direction of the house should be facing the gate, the direction you face is facing the direction, and the back is sitting. So all the houses facing south in China are north houses, and the doors are open on the south wall of the houses. In modern architecture, the orientation of doors is mostly east-west, so the sitting posture now mostly depends on which direction the main lighting surface of the room is. If the lighting surface of the main house is in the south, it is said that it faces south, while the northern house you mentioned faces south if it is an old house, and faces north if it is a new building now.

Architectural orientation mainly refers to the facade of the building, or the direction of the main facade of the building. There are two situations here. First, for residential buildings, the main facade refers to the facade where the main room is located; Second, public buildings, the facade or main facade may refer to the most prominent and important facade in the image of the building, or the facade where the main entrances and exits are located.

The so-called house orientation generally refers to the place with the largest lighting surface. Small houses in rural areas of China generally have the largest lighting area at the gate. In urban housing, the main balcony is generally the largest lighting surface of each unit.

It will have a certain impact on the lighting, ventilation, noise and energy saving of buildings. A good orientation will make you warm in winter and cool in summer, while a bad orientation will not only affect the comfort of living, but sometimes even endanger the health of residents because of ventilation and other problems.

Static objects on the earth generally have stable orientations, including animals, plants and various man-made objects. For the virtual world in the computer, the orientation of objects should follow the laws of the real world. However, the existing 3D modeling software and 3D scanning equipment are all based on their own local coordinate system, which can't guarantee that the derived model orientation is positive. Moreover, in practical problems such as model retrieval, large-scale scene modeling and perfect angle selection, if the positive direction of the model has been determined, it will bring a lot of convenience to the subsequent algorithms.
