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

[0016] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0017] A dynamic scheduling method for a three-dimensional model based on a geometric center, comprising the steps of:

[0018] (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.

[0019] (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...

Abstract

The invention discloses a three-dimensional model dynamic scheduling method based on a geometric center. The method comprises the following steps of (1), dividing states of a model packet in a memory to four kinds; (2), dividing the models into three kinds; (3), dividing a three-dimensional space into six different areas; and (4), performing three-order multistage model scheduling, and utilizing a new triggering method in model conversion. The three-dimensional model dynamic scheduling method is advantageous in that memory optimization is realized based on real-time blanking; and an operation bottleneck of a big data three-dimensional scene on a mobile terminal is finally broken. The three-dimensional model dynamic scheduling method can realize more effective real-time rendering and blanking of the three-dimensional model, and breaking restriction by a hardware condition of the mobile equipment, thereby supplying a technical basis for smooth operation of a virtual three-dimensional scene on the mobile terminal, and realizing true three-dimensional smooth operation on the mobile terminal.

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 of a three-dimensional model based on a geometric center. 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 poss...
