All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

The following terms are used herein.

And the switching chain is used for managing the display of the graphic frames in the windowed application program, allowing the graphic frames to be prepared in the background and then presented on a screen at a proper time, so that smooth animation and graphic rendering effect are realized.

Example 1

An embodiment of the present application provides a stereoscopic display method of a display device, where the method is applied to a stereoscopic display system, and the stereoscopic display system includes a host and at least one display device, where the host is communicatively connected to the at least one display device, and the method may include the following steps, as shown in fig. 1:

step S101, performing an initialization operation and creating a context object corresponding to the display device;

step S102, creating a left eye camera and a right eye camera according to the context object;

step S103, determining a left-eye rendering target according to the left-eye camera, and determining a right-eye rendering target according to the right-eye camera;

step S104, executing a first operation of frame circulation according to the left-eye rendering target, and executing a second operation of frame circulation according to the right-eye rendering target;

and step 105, performing synthesis processing according to the result of the first operation and the result of the second operation, so as to realize stereoscopic display.

The above steps are described in detail below.

Specifically, in some examples, the stereoscopic display system may include a host and n display devices, where n is an integer greater than or equal to 1. The display device may be a conventional screen, an arc screen, a special-shaped screen, a creative screen, etc., which is not specifically limited by the embodiments of the present application. The method provided in steps S101 to S105 described below is for each display device. For ease of understanding, the display device, specifically, the ith display device, will be described below as device_i.

Specifically, in some examples, before executing the step S101, the stereoscopic display system may determine whether the hardware of the display device supports stereoscopic display, and if it is determined that the hardware of the display device does not support stereoscopic display, exit, so that rendering may be performed according to a monocular rendering method; if it is determined that the hardware of the display device supports stereoscopic display, the process advances to step S101.

Specifically, in some examples, for step S101, an initialization operation may be performed and a context object corresponding to the display device may be automatically created at the start-up of the system. Wherein, the corresponding automatic creation of the context object corresponding to the display device can be different corresponding to different display devices, and the corresponding relation between the display device and the corresponding context object can be preset. Wherein the context object of the display device, in particular, refers to a core object for managing and executing graphics rendering operations, which is associated with a specific graphics processor, i.e. GPU, which allows a user to send rendering commands to the GPU in an application program, enabling drawing, rendering and operation of graphics.

Specifically, in some examples, for step S102, for example, two cameras for the left and right eyes may be added to the upper layer of the Unity engine, and the cameras for the left and right eyes may be displayed in a stereoscopic manner. Here, the left-eye camera created is denoted as reftcamera_i, and the right-eye camera is denoted as lightcomera_i. Further, the process advances to step S103, where a left-eye rendering target is determined from the left-eye camera and a right-eye rendering target is determined from the right-eye camera.

Specifically, in some examples, for step S104, a first operation of a frame cycle may be performed according to the left-eye rendering target, and then a second operation of a frame cycle may be performed according to the right-eye rendering target; alternatively, the second operation of the frame cycle may be performed according to the right-eye rendering target, and then the first operation of the frame cycle may be performed according to the left-eye rendering target. The order in which the first operation of performing the frame cycle on the left-eye rendering target and the second operation of performing the frame cycle on the right-eye rendering target are not particularly limited in the embodiments of the present application.

Specifically, in some examples, with respect to step S105, the display device may implement stereoscopic display after the first operation according to the frame cycle is performed and the second operation according to the frame cycle is performed. Therefore, after wearing equipment such as 3D glasses and the like, relevant personnel can watch the image effect displayed by the display equipment in a three-dimensional mode.

In addition, in some embodiments of the present application, the application program corresponding to the method may be integrated into a Unity plugin, where the Unity plugin is installed in a Unity engine, and the Unity engine is installed in the host. In some other examples, the method may also be applied to a fantasy engine, an IdeaXR engine, etc., which is not particularly limited in the embodiments of the present application. When the application program corresponding to the method can be integrated in the Unity plugin, the Unity plugin can be specifically a unitySDK. Those skilled in the art will understand that the UnitySDK is a file in unitypackage format, which is a proprietary format of a Unity plug-in package, and is mainly used for related developers to import plug-ins into a Unity engine to call related interfaces to create and secondarily develop virtual reality immersive environment contents. Among them, the built-in functions may include, but are not limited to, scene roaming, scene jumping, character snap, UI interactive click, UI interactive drag, object interactive click, object interactive drag, etc.

It can be understood that, the support for the stereoscopic effect is removed from the Unity engine of the version 2020 and above, and the codes provided by the Unity engine in the related art are closed sources, so that the logic of the workflow thereof cannot be known to the person skilled in the art, and therefore, the stereoscopic effect is difficult to realize on the version.

Further, in practical application, virtual reality contents manufactured by a Unity, unreal, ideaVR, VRDO content creation engine can be quickly adapted to LED direct screen, three-folded screen, cave and other virtual reality immersive large screen interaction environments and zSpace hardware environments through LinkXR. In some examples, a user may perform immersive interaction experience on VR content with any VRPN protocol-based optical tracking system and interaction device, and support performing interaction experience on the head-displayed VR content directly in a virtual reality immersive large-screen interaction environment or zSpace hardware environment without modification, and have a 3D stereoscopic effect. In addition, positioning unification based on a real physical space can be performed on the head-mounted display device, so that the relative position relation of each person in the virtual scene is consistent with the real scene, and local multi-person collaborative content experience consistent with the real physical space is provided.

It is found that, compared with the related art, the embodiment of the application provides a stereoscopic display method of a display device, which is applied to a stereoscopic display system including a host and at least one display device, the host and the at least one display device being communicatively connected, by performing an initialization operation and creating a context object corresponding to the display device, then creating a left-eye camera and a right-eye camera according to the context object, and determining a left-eye rendering target according to the left-eye camera, determining a right-eye rendering target according to the right-eye camera, and further performing a first operation of a frame cycle according to the left-eye rendering target, performing a second operation of a frame cycle according to the right-eye rendering target, and performing a composition process according to a result of the first operation and a result of the second operation, stereoscopic display is achieved, so that a display device that does not originally support stereoscopic display can achieve an effect of supporting stereoscopic display.
