Hierarchical detail processing method of VR model

Abstract

The invention discloses a hierarchical detail processing method of a VR model, and a light spot flashing problem generated in an animation process is solved, the real-time rendering speed in operation can be accelerated. The secondary development of VR is carried out through the OpenGI technology, a different-visual-angle multi-layer resolution display algorithm is applied, and the problems of a poor computer rendering effect and a slow display speed are solved. According to the position and importance degree of an object model node in a display environment, the resource allocation of object rendering is determined, the face number and detail of a non-important object are reduced, and thus the efficient rendering operation is obtained. In the real-time drawing generation, according to the difference of a viewpoint, the selective real-time refinement of a complex model is carried out, a middle model with different detail levels between an initial fine model and a rough model can be generated, an image jump phenomenon in the one-by-one storage of a plurality of discrete LOD models generated in advance is avoided, the storage space of the model is saved, and the image has continuity.

Description

technical field [0001] The invention relates to the technical field of virtual reality, in particular to a method for processing hierarchical details of a VR model. Background technique [0002] Virtual reality technology is a human-machine interface technology that highly realistically simulates human behaviors such as seeing, hearing, and moving in a natural environment. The multi-dimensional information space supported by its key technologies enables participants to have a highly realistic "reality" feeling. Among them, the visual channel is the most important interface in the virtual environment system. It is generally believed that nearly 80% of the information that humans obtain from the outside world is obtained through human vision. [0003] The human visual system is very sensitive and strict. Any motion vision that does not satisfy the laws of physics and optics, and any video sequence with poor synchronization will bring additional stimulation to the visual syste...

However, the system does not provide coordination between the application process and the computing process, and the user must spend a lot of energy coordinating the two.
