Although a plurality of devices are illustrated for the computer 1100 in FIG. 1, the present invention may relate only to some of the devices therein, for example, the web server 1100 relates only to the processor 1110 and the storage device 1120 and the like. A technician can design instructions in accordance with the disclosed aspects of the present invention. How the instructions control the processor for operation is well known in the art and will not be described in detail herein.

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

In step S2100, in response to the loading request for the target virtual reality scenario, the unique model resource in the current virtual reality scenario is deleted, and the shared model resource and the scene camera are reserved, wherein the unique model resource is unique in the corresponding virtual reality scenario. There are model resources, and the shared model resource is a model resource included in all virtual reality scenarios 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 (eg, 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, a tablet computer, or the like, for example, a virtual reality game, a virtual reality video playback application, and can provide a feeling of the user's virtual reality.

The virtual reality scene is generally generated according to various scene development tool platforms, including various model resources and a scene camera (Camera), which is a variety of buildings, people, vegetation, and virtual reality scenes that may be involved in the virtual reality scene. Corresponding 3D model resources for machinery, animals, mountains, rivers, landscapes, etc. In one example, the scenario development tool platform can be Unity3D, a multi-platform integrated game development developed by Unity Technologies that allows users to easily create interactive content such as 3D video games, architectural visualizations, real-time 3D animations, and more. The tool is a fully integrated professional game engine.

In this embodiment, various model resources included in the virtual reality scenario may be divided into a shared model resource and a unique model resource according to actual application requirements. For example, the unique mode The type resource is a unique model resource in the corresponding virtual reality scenario, and the shared model resource is a model resource included in all virtual reality scenarios involved in the current virtual reality application. Therefore, in one example, the virtual reality scene loading method provided in this embodiment further includes: classifying model resources included in all virtual reality scenarios involved in the current virtual reality application to determine the shared model resource and All unique model resources contained in each virtual reality scenario involved in current virtual reality applications. For example, by classifying the tags (labels) included in the model resources included in the virtual reality scenario, the model resources included in all the virtual reality scenarios involved in the current virtual reality application are marked as common model resources by tags, and other models are Resources are tagged 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 by the virtual reality scene in the prior art may be defined. . The scene life cycle mechanism in the prior art defines that the model resource included in the virtual reality scene and the scene camera have the same scene life cycle. When the scene life cycle arrives, for example, the current virtual reality scene needs to be ended, and the target virtual reality scene is loaded. When the scene is redirected, the model resources and scene cameras included in the current virtual reality scene are all destroyed. When the target virtual reality scene is loaded, all the model resources included in the target virtual reality scene need to be reloaded, which may be limited. The processing capability of the terminal device running the virtual reality application, the loading time is too long, and the black screen affects the user experience. The scene life cycle mechanism is an inherent mechanism of the development tool platform (for example, Unity3D) of the current virtual reality scenario. In the embodiment of the present invention, the model resource may be divided into the shared model resource and the unique model resource in the target virtual reality scenario. Then, the mechanism for the shared model resource and the scene camera is no longer implemented in the scene life cycle, so that when the scene jump is performed on the target virtual reality scene, the shared model resource and the scene camera can be reserved, thereby avoiding repeated loading of the shared model resource and shortening the scene. Load time, keep the scene camera to avoid black screen.

After step S2100, proceeding to step S2200, loading a unique model resource of the target virtual reality scene, for presenting the unique model resource according to the target real scene, the shared model resource, and the scene camera Target virtual reality scene.

Loading the target virtual reality scene by using the virtual reality scene loading method as shown in FIG. 2 When the shared model resource and the scene camera are not repeatedly loaded, the time for loading the target virtual reality scene is shortened, and the scene camera is retained to avoid the black screen phenomenon. Improve the user experience.

The shared model resource and the scene camera may be saved in the corresponding virtual reality application or in the terminal device running the corresponding virtual reality application, or may be stored in the remote server or the 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 virtual reality scene loading method provided in this embodiment further includes dynamically loading the shared model resource and the scene camera when loading the initial virtual reality scene.

In an example, step S2100 may be performed, and step S2200 may be performed to implement a unique model resource in a target virtual reality scene of the target virtual reality scene that the user requests to load when the user performs an interaction operation on the virtual reality scene. The asynchronous load backup is performed in a multi-threaded manner to further shorten the load time of the target virtual reality scene, and the user experience of realizing the scene jump without waiting. Therefore, the method for loading the 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 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 included in the scene and the scene camera are Prefab encapsulated. For example, the model resources included in the virtual reality scene and the scene camera (Camera) are Prefab encapsulated by Unit3D. This can simplify the loading process of the virtual reality scene and shorten the loading time of the virtual reality scene.

When the virtual reality scene loading method is provided in the foregoing embodiment, when the target virtual reality scene is loaded, the shared model resource and the scene camera may not be repeatedly loaded, and the time for loading the target virtual reality scene is shortened, and the time is retained. The scene camera can avoid black screen phenomenon. Improve the user experience.
