Embodiment Construction
[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0025] Taking the three-dimensional digital campus of Nanjing University Drum Tower Campus as an example, the present invention is used to realize smooth running of the three-dimensional digital campus of Nanjing University Drum Tower Campus. The working process is described as follows:
[0026] (1) Construction of 3D campus scene. The Drum Tower Campus of Nanjing University covers an area of about 800 mu. If the basic strategy of simplifying the geometric features of the 3D model, using textures and maps, and rendering proposed by the present invention is not adopted, the total data volume is 2.3G. The full version of the 3D campus of the Drum Tower Campus needs to be in Only a PC with better performance can run smoothly, and directly porting to a tablet or mobile phone will cause the system to crash. After adopting the three-dime...

The invention discloses a three-dimensional model comprehensive dynamic scheduling method and belongs to a field of three-dimensional virtual reality scheduling. The method includes steps of 1, three-dimensional model geometric feature simplification; 2, three-dimensional model material simplification; 3, three-dimensional model rendering and optimization; 4, visible range determination and primary blanking of the three-dimensional model; 5, blanking with utilization of shielding of objects in a three-dimensional scene; 6, LOD blanking, 7, dynamic scheduling on objects based on central coordinates of the objects in the three-dimensional scene. The method has beneficial effects that more effective real time rendering and blanking of the three-dimensional model can be realized and constraints of hardware conditions of a mobile device can be eliminated, so that a technical basis is provided for smooth operation of the virtual three-dimensional scene on the mobile terminal and smooth operation of true three-dimension on the mobile terminal is realized.
Description
technical field [0001] The invention belongs to the field of three-dimensional virtual reality scheduling, and in particular relates to a comprehensive dynamic scheduling method for three-dimensional models. 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 displa...
