Detailed Description
The present invention will be described in detail with reference to specific examples. The following examples will assist those skilled in the art in further understanding the invention, but are not intended to limit the invention in any way. It should be noted that it would be obvious to those skilled in the art that various changes and modifications can be made without departing from the spirit of the invention. All falling within the scope of the present invention.
The method for the multi-user object distinguishing processing provided by the invention comprises the following steps:
an interactivity defining step: defining a virtual object in a virtual environment as a non-interactive virtual object or an interactive virtual object; the virtual environment is displayed to a plurality of users by a plurality of VR glasses at the same time, and the users refer to VR glasses wearers; specifically, the virtual environment is an interactive scene, and a plurality of users have corresponding virtual cameras in the interactive scene, so that the visual angles of the users are different, and the virtual cameras can move at different positions and orientation angles under the control of the users, so as to obtain different visual angles. Under the interactive scene, the virtual objects can be shot by all the virtual cameras, for example, an interactive scene is outdoor picnic, the virtual objects such as picnic mats, dinner plates, food, flowers near the picnic, mountains far away, forests far away, deer herds far away and the like can be observed and seen by each user of a plurality of users, and after one user eats the food virtually for a bite, a bitten gap is formed on the virtual food, and the gap can be seen by other users.
Non-interactive virtual object processing: for the non-interactive virtual object, displaying images of the non-interactive virtual object at the same view angle to the plurality of users; in a preferred example, in the non-interactive virtual object processing step, for a non-interactive virtual object, images of the non-interactive virtual object at the same viewing angle and the same viewing distance are displayed to the plurality of users. Specifically, the virtual object is divided into the interactive virtual object and the non-interactive virtual object aiming at all users, and the observable visual angle and the distance of the non-interactive virtual object are fixed, so that a large amount of computing resources for drawing the virtual object from different visual angles are saved. Defining the virtual object with the observation distance larger than or equal to the distance threshold value as a non-interactive virtual object; and defining the virtual object with the observation distance smaller than the distance threshold value as the interactive virtual object. For example, a virtual object with an observation distance exceeding 100 meters in a virtual environment is positioned as a non-interactive object, for example, a remote mountain, a remote forest, a remote deer swarm, and a remote sea are defined as non-interactive objects, and each user is provided with only one view angle and distance image, if N users are in an interactive scene, the computing resources at N-1 user view angles can be saved, the more users, the more resources the present invention can save, and in a large interactive scene, for example, a virtual football field, a large amount of computing resources can be saved for hundreds or even thousands of users.
An interactive virtual object processing step: and for the interactive virtual object, respectively displaying different images of the interactive virtual object under each user visual angle to the plurality of users. Specifically, the interactive virtual object still presents images at different viewing angles and distances to each user, and on the premise of not influencing interaction and multi-user multi-viewing angles, required computer operation resources are greatly reduced through the non-interactive virtual object.
Further, initially, all virtual objects are defined as non-interactive virtual objects; the non-interactive virtual object is positioned as an interactive virtual object after interacting with any one of the plurality of users. And if the time that the interactive virtual object is not interacted by any user in the plurality of users is more than or equal to the time threshold, defining the interactive virtual object as a non-interactive virtual object until the interactive virtual object is defined again after any user interacts. Thereby realizing dynamic self-adaptive adjustment of the interactive definition of the virtual object.
The foregoing description of specific embodiments of the present invention has been presented. It is to be understood that the present invention is not limited to the specific embodiments described above, and that various changes or modifications may be made by one skilled in the art within the scope of the appended claims without departing from the spirit of the invention.
