Model loading method, server and terminal

Abstract

The embodiment of the invention provides a model loading method applied to a server, and the method comprises the steps: carrying out the layering of a model, obtaining layered models with different precisions, and enabling each layered model to be composed of triangular patches with the corresponding precision; performing double marking on vertex data of all triangular patches according to the precision of the hierarchical model from coarse to fine; wherein the first mark information is the number of a hierarchical model with the coarseness of the vertex data, and the second mark informationis the serial number of the vertex data in a preset vertex sequence; receiving a download request sent by the terminal, recording loading condition parameters of the terminal in the request, selectingvertex data of the target hierarchical model according to the loading condition parameters, and returning the vertex data to the terminal for the terminal to load; wherein the precision of the targethierarchical model is in positive correlation with the loading condition parameters. The embodiment of the invention solves the problem that a terminal with relatively low performance and relativelypoor network environment may have a jamming phenomenon when loading and rendering a model with relatively high fineness in a traditional scheme.

Description

technical field [0001] Embodiments of the present invention relate to the field of computer technology, and more specifically, to a model loading method, server and terminal. Background technique [0002] The rise and promotion of virtual reality technology VR (Virtual Reality) and augmented reality AR technology (Augmented Realty) put forward high requirements for the interaction between the model and the virtual or real world. With the development of computer graphics and the improvement of terminal GL specifications, it is possible to realize VR and AR interaction on terminal browsers, so that high-performance real-time Loading and rendering are particularly important. [0003] The existing method of loading the rendering model in the mobile terminal browser is that when the user generates a specific interaction event with the browser page, the browser downloads the model from the remote server, reads it into the memory and performs a series of operations to complete the...

Problems solved by technology

In this case, the browsers of mobile devices with lower performance will suffer from serious freezes and dropped frames, and the fluency and authenticity will be greatly reduced

[0006] 3. When the number of models is large, since all models maintain fine precision by default, the performance will decrease as the number of models increases
