Problems solved by technology

However, this method cannot guarantee that the position of the camera observation point does not pass through the model while ensuring the details of some models. When passing through the model, the details of the passed part of the model will be too enlarged, which will affect the display effect of the model.

Embodiment Construction

[0024] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. The following examples are only used to illustrate the technical solutions of the present invention more clearly, and cannot be used to limit the protection scope of the present invention.

[0025] figure 1 A schematic flowchart of a method for browsing a three-dimensional model provided by this embodiment is shown, including:

[0026] S101. Build a virtual mask according to a target sub-model in a three-dimensional model, so that the target sub-model is in the virtual mask.

[0027] Specifically, the three-dimensional model is a model that can perform operations such as three-dimensional rotation, movement, zoom-in, and zoom-out, for example, a three-dimensional map model including streets, houses, and the like.

[0028] The target sub-model is the currently concerned object, which may be a residential area, a building or a certain suite.

Abstract

The embodiment of the invention discloses a browsing processing method and device for a three-dimensional model, and the method comprises the steps: building a virtual mask according to a target sub-model in the three-dimensional model, so that the target sub-model is in the virtual mask; in the process of browsing the three-dimensional model, obtaining the current camera observation point position according to the current display interface of the three-dimensional model; and if it is judged that the position of the camera observation point reaches the position where the virtual mask is located, preventing the position of the camera observation point from moving into the virtual mask. By constructing the virtual mask of the target sub-model, the camera observation point position is controlled not to reach the virtual mask, it can be guaranteed that the camera observation point position does not penetrate through the model, it can also be guaranteed that a user can clearly see model details, and the optimal display effect of the model is achieved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of computers, and in particular, to a method and device for browsing and processing a three-dimensional model. Background technique [0002] In the scene of browsing the 3D model, the user can freely zoom in and out of the 3D model through the zoom ratio. However, due to the limitation of the fineness of the 3D model during construction, in order to ensure the visual effect of model browsing, the position of the camera observation point is not allowed to be too close to the target object, that is, it is too narrow; The distance between the point position and the target object cannot be limited too far, that is, it is too enlarged. [0003] In the prior art, the zoom ratio of the model is controlled by limiting the distance value of the camera observation point position from a certain point. Once the distance value is lower than this distance value, the camera observation point position...
