Method and device for hierarchically loading and unloading objects in three-dimensional virtual reality scene

Abstract

The invention discloses a method and a device for hierarchically loading and unloading objects in a three-dimensional virtual reality scene. The method comprises the following steps of: determining hierarchy of the objects in a tree management structure and nodes corresponding in the tree management structure after sensing actions of the objects in a click three-dimensional virtual reality scene; and after receiving a command entering next hierarchy, loading all objects of the next hierarchy in the three-dimensional virtual reality scene and unloading all objects of the hierarchy where the objects are positioned if the node corresponds to the next hierarchy. The invention further discloses a device for hierarchically loading and unloading the objects in the three-dimensional virtual reality scene.

Description

technical field [0001] The invention relates to the technical field of three-dimensional virtual reality, and in particular to a method and a device for loading and unloading objects by layers in a three-dimensional virtual reality scene. Background technique [0002] Virtual reality technology has a virtuality beyond reality. It is a new computer technology developed with multimedia technology. It uses three-dimensional graphics generation technology, multi-sensor interaction technology and high-resolution display technology to generate a three-dimensional realistic virtual environment. Users need Access to the virtual environment is only possible through special interactive devices. Virtual reality technology has greatly advanced the development of computer technology, and one of its main functions is to generate virtual reality scenes. Virtual reality technology has been used in various aspects such as industry, architectural design, education and training, culture and e...

Problems solved by technology

[0003] With the rapid development of computer image processing technology, users have higher and higher requirements for the display quality of virtual reality scenes. The details of all objects in the scene not only occupy a large amount of computer memory, but also have very high requirements for the central processing unit (CPU) and image processing unit (GPU); although the display of all details improves the picture quality displayed by the computer, However, it reduces the smoothness of the screen operation, and even the phenomenon of computer suspended animation will appear during the operation process.
