Embodiment 3

[0034] The comprehensive dynamic scheduling method of the 3D model in this embodiment includes the following steps:

[0035] S1. Establish a fine 3D model and a rough 3D model for each object;

[0036] In order to reduce the amount of computation, it is recommended to use a model with a smaller size. The present invention divides the actual object into several sub-units, and then builds a three-dimensional model for the sub-units. That is, the object described in step S1 is a subunit of real object segmentation;

[0037] S2. Both the fine 3D model and the rough 3D model have four stages: the first stage—unloaded, the second stage—loaded as a memory image, the third stage—release resource packs, and the fourth stage—instantiate; When the model is in the instantiated state, the corresponding object becomes visible, otherwise the corresponding object is invisible;

[0038] S3, such as figure 1 As shown, taking the current camera position as the center, the area in the viewing ...

Abstract

The invention relates to a three-dimensional model comprehensive dynamic scheduling method, which establishes a fine model and a rough model for each object, partitions the inside and outside of the viewing cone, and according to the rendering requirements of each partition in the three-dimensional visualization process, and each The transformation process between partitions should meet the requirements of fluency for dynamic scheduling of 3D models. The invention breaks through the limitation of hardware to a certain extent, greatly reduces the consumption of video memory and internal memory in 3D interactive scenes, and makes it possible for mobile devices to run real 3D detailed model large scenes. The invention can be directly applied to PC (Personal Computer) customers Transform and optimize the 3D virtual scene on the terminal, and realize the transplantation of the scene to the mobile terminal.

Description

technical field [0001] The invention relates to a three-dimensional model comprehensive dynamic scheduling method, which belongs to the field of three-dimensional virtual reality scheduling. Background technique [0002] The projection method of traditional two-dimensional maps determines that abstract symbols must be used to express ground features, which cannot give people an intuitive feeling, especially when the ground features are complex, it is difficult for two-dimensional maps to accurately reflect surface information. However, on this issue, three-dimensional virtual reality technology can just meet people's needs. [0003] The current virtual reality technology first needs to establish a 3D model, and then unify or fragment it to complete the loading at one time, which can realize 3D roaming. However, the amount of 3D model data is huge, and if you want to achieve the effect of smooth roaming, the hardware configuration requirements of the computer are relatively ...
