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. A fine model and a rough model are established for each object; partition is carried out at the inner part and outer part of a view frustum; and according to rendering requirements of different partitions in a three-dimensional visualization process and a requirement that fluency should be met in a process of conversion between different partitions, three-dimensional-model dynamic scheduling is carried out. The three-dimensional-model comprehensive dynamic scheduling method breaks through restraint by hardware in a certain degree and greatly reduces consumption of a video memory and an internal storage from a three-dimensional interaction scene so that it is possible for a mobile device terminal to run a true three-dimensional detail model scene. The method is directly applicable to transformation and optimization of a three-dimensional virtual scene of a PC (Personal Computer) client so that transplantation of the scene to a mobile terminal is realized.

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 ...
