A 3D model processing method for terminal display

Abstract

The invention discloses a three-dimensional model processing method for terminal display, comprising: converting the generated three-dimensional model material into a PBR material according to a predetermined material conversion method; using a secondary error measurement method to model the generated three-dimensional model Simplification: discretize the geometric information of the simplified 3D model or hierarchical 3D model by using the floating point quantization method to realize the compression of the 3D model or hierarchical 3D model; compress the compressed 3D model or the simplified 3D model according to the resolution The triangular patches of the model are divided into multiple levels, and all the triangular patches contained in each level constitute the hierarchical 3D model corresponding to this level; all levels after model material conversion, model simplification, model compression and model level division are processed The 3D model is transmitted to the terminal for rendering in sequence according to the priority of the layer, or transmitted to the terminal for rendering in sequence according to the priority of the layer.

Description

technical field [0001] The invention relates to the field of graphics, in particular to a three-dimensional model processing method for terminal display. Background technique [0002] With the rapid development of technologies such as HTML5 and VR / AR, the requirements for displaying and editing 3D models on terminals have become more and more common. However, there will be many problems in the process of transmitting the built 3D model to the terminal and displaying it, as follows: [0003] (1) The material of the 3D model generated by the modeling tool is inconsistent with the material of the rendered model used by the terminal, which will directly cause confusion in the rendering process of the 3D model and affect the rendering quality. [0004] (2) The 3D model generated by the modeling tool is relatively fine and contains a large number of triangular faces. When the terminal is rendered, it will occupy a large amount of operating memory of the terminal processor, increa...

AI Technical Summary

Problems solved by technology

[0003] (1) The material of the 3D model generated by the modeling tool is inconsistent with the material of the rendered model used by the terminal, which will directly cause confusion in the rendering process of the 3D model and affect the rendering quality

[0004] (2) The 3D model generated by the modeling tool is relatively fine and contains a large number of triangular faces. When the terminal is rendered, it will occupy a large amount of operating memory of the terminal processor, increase the computing overhead of the terminal processor, and reduce rendering efficiency. The precision adjustment of the rendered product cannot be made according to the visual requirements

[0005] (3) The 3D model generated by the modeling tool contains a large number of triangles, so that the storage capacity of the 3D model is very large, which will reduce the transmission efficiency of the 3D model

[0006] (4) Since the built 3D model is only displayed with one precision on the terminal, it will affect the user's interactive experience

[0007] (5) There will be potential safety hazards during the transmission of the 3D model
