the first house model and the second house model are in the same-screen and same-view display state before the view angle of the user is changed; the first house three-dimensional model is a three-dimensional model of a current house, and the second house three-dimensional model is a three-dimensional model of a finished house loaded with a recommended finishing effect.
The three-dimensional model of the current house refers to a three-dimensional model of the house of the actual house source (a three-dimensional model of the house before decoration). The decorated house three-dimensional model is based on a corresponding actual house source and simulates a decorated house three-dimensional model (a decorated house three-dimensional model).
The recommended decoration effect refers to the decoration effect after various furniture household appliance models are added in the three-dimensional model of the house after all existing decoration furniture household appliances of the house are erased in the three-dimensional model of the original house of the user according to the house attributes of the user, such as house types, orientation, lighting, floors and the like.
The user can wander and/or pan in a virtual three-dimensional space (VR space) of the three-dimensional model of the house to achieve an immersive house-viewing effect. Wandering, such as moving from one point location to another; look, for example, at a certain part of the room. Before the view angle of the user roaming and/or panning changes, the house three-dimensional model before decoration and the house three-dimensional model after decoration are displayed on a display interface of a user terminal (front end) at the same screen and the same view angle. The user can walk and/or scan in the virtual three-dimensional space of the house three-dimensional model before decoration, and can also walk and/or scan in the virtual three-dimensional space of the house three-dimensional model after decoration.
When the user sweeps at a point, the direction of the eyes can be switched (for example, by sliding the screen), so that the user can sweep different areas of the room; when a user moves from one point location to another point location, the viewing angle is inevitably changed, and the viewing direction can be further converted after the user moves to a new point location, so that the viewing angle is newly changed.
Therefore, when the user changes the visual angle at the same point, the visual angle can be changed by acquiring the visual line direction change information; when a user moves from one point location to another point location, the view angle change information can be obtained by obtaining the point location change information; when the user moves from one point location to another point location and further converts the direction of the line of sight, the view angle change information can be acquired through the point location change information and the view angle change information.
When a user roams and/or scans in a virtual three-dimensional space of a house three-dimensional model, a user terminal acquires information of a current virtual three-dimensional space where the user is located, wherein the current virtual three-dimensional space corresponds to the house three-dimensional model before decoration or corresponds to the house three-dimensional model after decoration; and obtain perspective change information of a user's roaming and/or panning in the current virtual three-dimensional space.
