Embodiment Construction

[0019] The method for quickly calculating the sending timing and range of location information in the Internet virtual reality environment of the present invention is based on the concept of effective interaction range (Area Of Interest, AOI), cutting the virtual scene with squares or staggered squares Method to calculate the AOI range, refer to figure 1 The example shown shows that a virtual scene 11 is divided into blocks numbered 1 to 25 by a square cutting method, wherein the user is located in the block numbered 12, and the user block 12 is adjacent to Blocks 6, 7, 8, 11, 13, 16, 17, and 18 are defined as low-interaction AOI ranges for users.

[0020] refer to figure 2 As shown, the method of the present invention uses a square cutting method to perform a square cutting on the blocks in the low-interaction AOI range of the aforementioned users, so that each block is further cut into four sub-blocks, as shown in the figure As shown, the user is located in the sub-block ...

Abstract

A method for fast calculating the transmission time and range of position information over Internet includes such steps as dividing the virtual scene into multiple area blocks for calculating effective interaction range, defining that the current area block and adjacent area blocks are low-interactivity effective interaction range, dividing each area block into multiple sub-area blocks, defining that the current sub-area block and adjacent sub-area blocks are high-interactivity effective interaction range, and transmitting information for state correction when the inconsistency of virtual environment reaches the valve in interactive range.

Description

technical field [0001] The present invention relates to the technical field of a three-dimensional multi-person interactive system in a virtual reality environment, especially a method for quickly calculating the sending timing and range of location information in an Internet virtual reality environment. Background technique [0002] Due to the development of virtual reality and network technology, the three-dimensional space (3D) multi-person interactive system can be realized. Through this interactive system, users all over the world can talk to each other or have Other interactions, and with the prevalence of the Internet, the application of 3D multi-person interactive systems has become more popular. [0003] In the 3D multi-person interactive system, the interaction of users in the scene is transmitted through the network. Therefore, the interactive information of the users in the scene must be transmitted and processed very quickly. The delay of channel transmission w...
