<Example>

A method for loading a virtual reality scene is provided in this embodiment, as shown in FIG. 2 , including:

Step S2100, in response to the loading request of the target virtual reality scene, delete the unique model resources in the current virtual reality scene, and keep the shared model resources and the scene camera, wherein the exclusive model resources are the unique model resources in the corresponding virtual reality scene There are model resources, and the shared model resources are model resources included in all virtual reality scenes involved in the current virtual reality application.

In this embodiment, the virtual reality scene is a scene presented to the user by the current virtual reality application through a display device (such as a display screen of the virtual reality device, etc.). The virtual reality application is an application that can be run on a terminal device such as a mobile phone, a wearable device, or a tablet computer, for example, a virtual reality game or a virtual reality audio and video playback application program, which can provide users with a virtual reality experience.

The virtual reality scene is usually generated according to various scene development tool platforms, including various model resources and scene cameras (Camera), and the model resource is various buildings, characters, vegetation, etc. that may be involved in the virtual reality scene in the virtual reality scene. 3D model resources corresponding to machinery, animals, mountains, rivers, landscapes, etc. In one example, the scene development tool platform may be Unity3D, which is a multi-platform comprehensive game development developed by Unity Technologies that allows users to easily develop and create interactive content such as 3D video games, architectural visualization, and real-time 3D animation. Tool, is a fully integrated professional game engine.

In this embodiment, various model resources included in the virtual reality scene may be divided into shared model resources and unique model resources according to actual application requirements. For example, the exclusive model resource is a unique model resource in the corresponding virtual reality scene, and the shared model resource is a model resource included in all virtual reality scenes involved in the current virtual reality application. Therefore, in an example, the virtual reality scene loading method provided in this embodiment further includes: classifying the model resources contained in all the virtual reality scenes involved in the current virtual reality application, so as to determine the shared model resources and All unique model assets contained in each VR scene involved in the current VR application. For example, by classifying the Tags (tags) that come with the model resources contained in the virtual reality scene, the model resources contained in all virtual reality scenes involved in the current virtual reality application are marked as shared model resources by Tag, and other models All resources are marked as unique model resources by Tag.

In step S2100, the unique model resource in the current virtual reality scene is deleted, and the shared model resource and the scene camera are reserved. Specifically, a mechanism different from the scene life cycle mechanism defined for the virtual reality scene in the prior art can be defined to achieve . The scene life cycle mechanism in the prior art defines that the model resources contained in the virtual reality scene and the scene camera have the same scene life cycle. When the scene life cycle is reached, for example, it is necessary to end the current virtual reality scene and load the target virtual reality scene When the scene jump is implemented, the model resources and scene cameras contained in the current virtual reality scene will be completely destroyed. When loading the target virtual reality scene, all model resources contained in the target virtual reality scene need to be reloaded, so there may be limitations Due to the processing capability of the terminal device running the virtual reality application, the loading time is too long, resulting in a black screen and affecting the user experience. The scene life cycle mechanism is the inherent mechanism of the development tool platform (such as Unity3D) of the current virtual reality scene. In the embodiment of the present invention, the model resources contained in the target virtual reality scene can be divided into shared model resources and unique model resources. Finally, the scene life cycle mechanism is no longer implemented for the shared model resources and scene cameras, so that when the target virtual reality scene is loaded and the scene jump is performed, the shared model resources and scene cameras can be retained to avoid repeated loading of the shared model resources and shorten the scene Loading time, keep scene camera to avoid black screen.

After step S2100, enter step S2200, and load the unique model resource of the target virtual reality scene, so as to present the Target virtual reality scene.

Through the virtual reality scene loading method shown in Figure 2, when loading the target virtual reality scene, it is not necessary to repeatedly load the shared model resources and scene cameras, shorten the time for loading the target virtual reality scene, and keep the scene camera, which can avoid A black screen appears. Improve user experience.

The shared model resource and scene camera can be stored in the corresponding virtual reality application or a terminal device running the corresponding virtual reality application, or can be stored in a remote server or a cloud server. When the target virtual reality scene is the initial virtual reality scene of the current virtual reality application, the shared model resource and the scene camera need to be loaded. Therefore, in an example, the method for loading a virtual reality scene provided in this embodiment further includes: when loading an initial virtual reality scene, dynamically loading the shared model resource and the scene camera.

In an example, step S2100 can also be executed at the same time as step S2200, so that when the user interacts with the virtual reality scene, the unique model resources in the target virtual reality scene that the user requests to load can be loaded. Asynchronous loading and backup is carried out in a multi-threaded manner, further shortening the loading time of the target virtual reality scene, and giving users the user experience of realizing scene jump without waiting. Therefore, the method for loading a virtual reality scene provided in this embodiment may further include: performing the step of loading the unique model resource of the target virtual reality scene by means of asynchronous loading.

In addition, in an example, the virtual reality scene loading method provided in the embodiment may further include: before performing the step of loading the target virtual reality scene, all virtual reality scenes involved in the current virtual reality application The model resources contained in and the scene camera are packaged in Prefab. For example, Unit3D is used to prefab package the model resources contained in the virtual reality scene and the scene camera (Camera). In this way, the loading process of the virtual reality scene can be simplified, and the loading time of the virtual reality scene can be shortened.

Through the virtual reality scene loading method provided in this embodiment described above, when loading the target virtual reality scene, it is not necessary to repeatedly load the shared model resources and scene cameras, shorten the time for loading the target virtual reality scene, and retain The scene camera can avoid black screen phenomenon.
