Problems solved by technology

However, due to the dual influence of the hardware limitations of the mobile terminal and the complexity of the 3D scene, there are still big problems in the smooth operation of the true 3D scene on the mobile terminal.

Embodiment Construction

[0021] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0022] A dynamic scheduling method based on center coordinate distance weighting, comprising the following steps:

[0023] (1) Divide the state of the model package in memory into four types: unloaded, loaded as a memory image, release resources, and instantiated; unloaded means that the model package is not scheduled; loaded as a memory image means that the model package is loaded into memory However, resources are not released; releasing resources refers to releasing the memory image of the model; instantiation refers to loading the model into the scene and making the model visible.

[0024] (2) The models are divided into three categories: high-level models, low-level models and general models; high-level models refer to high-definition models, which are mainly used to meet the needs of close-up viewing; low-level models refer to l...

Abstract

The invention discloses a dynamic scheduling method based on distance weighing of a central coordinate, and belongs to the field of 3D virtual reality scheduling. The method comprises the following steps that (1) states of a model package in a memory are divided into four types; (2) models are divided into three types; (3) a 3D space is divided into six different areas; (4) a frustum of distance weighing is pre-scheduled, and a distance weighing method is used to distribute a buffer area; and (5) three-order multistage model scheduling is carried out, and a new trigger method is used in model conversion. The dynamic scheduling method has the advantages that the memory is optimized on the basis of real-time blanking, and the operational bottleneck of a mobile end in a big-data 3D scene is overcome. The 3D model is rendered and blanked in real time more effectively, limitation of hardware conditions of mobile equipment is overcome, technical basis is provided for smooth operation of a virtual 3D scene in a mobile terminal, and real 3D smooth operation is the mobile end is realized.

Description

technical field [0001] The invention belongs to the field of three-dimensional virtual reality scheduling, and in particular relates to a dynamic scheduling method based on center coordinate distance weighting. Background technique [0002] The projection method of the traditional two-dimensional map determines that it must be expressed with abstract symbols, which cannot give people an intuitive feeling, especially when the ground features are complex, it is difficult for the two-dimensional map to accurately reflect. Under the new trend of the information age, smart phones and open source platforms are becoming more and more popular. Although the hardware conditions of embedded devices and computers are quite different, mobile devices have inherent advantages of portability and mobility. With the development of big data real-time rendering and real-time scheduling technology, coupled with the continuous improvement of mobile device hardware, it is gradually possible to dis...
