Method for mass model data dynamic scheduling and real-time asynchronous loading under virtual reality

Abstract

The invention discloses a method for mass model data dynamic scheduling and real-time asynchronous loading under virtual reality. The method includes the following steps of firstly, preprocessing 3D model scene data, secondly, cutting and partitioning a whole model scene, thirdly, conducting multithreading parallel distribution loading and fourthly, clipping a view cone. Based on a view cone clipping algorithm for acquiring the point of intersection of the view cone and a topographic region, real-time clipping based on the topographic region in dynamic scheduling is achieved, by the adoption of a multithreading processing mechanism of a model data partitioning scheduling and rending pipeline, a dynamic scheduling and drawing pipeline and a data processing scheduling pipeline between different mediums can be asynchronously loaded, and therefore dynamic balance of loading and performance efficiency of the mass scene model data is achieved in the hardware environment with a limited memory, a limited processor and the like.

technical field [0001] The invention belongs to the field of geological exploration, in particular to a method for dynamic scheduling and real-time asynchronous loading of massive model data under virtual reality. Background technique [0002] In the traditional virtual reality system, due to the limitations of the system architecture, model structure, network bandwidth, computer hardware CPU and GPU computing power, memory, video memory size, etc., the 3D scene is statically preloaded into the system memory, and the model cannot be real-time Perform complex operations such as dynamic organization and scheduling, and it is even more impossible to load massive model data into the system. Some systems that implement dynamic scheduling will also cause serious data reading due to massive scene model data and limited network bandwidth or GPU operating capabilities.

[0002] In the traditional virtual reality system, due to the limitations of the system architecture, model structure, network bandwidth, computer hardware CPU and GPU computing power, memory, and video memory size, the 3D scene is statically preloaded into the system memory, and the model cannot be real-time. Perform complex operations such as dynamic organization and scheduling, and it is even more impossible to load massive model data into the system. Some systems that implement dynamic scheduling will also cause serious data reading due to massive scene model data and limited network bandwidth or GPU operating capabilities. Write delay and data blockage, thus reducing the loading fluency of the 3D virtual scene model and the consistency of operation, greatly reducing the user's use and operation experience
