Abstract

The invention discloses a three-dimensional model and material merging method and device, a terminal, a storage medium and a rendering method, and belongs to the technical field of image rendering. The merging method comprises the steps of obtaining a three-dimensional model file, a material file and a texture map; determining a map arrangement mode; after the materials are subjected to duplicateremoval processing, combining and splicing texture maps of all the channels according to the determined map arrangement mode, and obtaining texture map puzzles of all the channels; and optimizing thestorage size of the three-dimensional model and the texture mapping puzzle of each channel, generating a configuration file and storing the configuration file. According to the method, the three-dimensional model and material merging speed is increased, the data storage amount is reduced, the data loading amount of the rendering CPU is further reduced, and the rendering efficiency is improved.

Description

technical field

[0001] The invention belongs to the technical field of image rendering, and in particular relates to a three-dimensional model and material combining method, device, terminal, storage medium and rendering method. Background technique

[0002] Multi-model and material merging technology refers to the technology of merging the BaseColor channel map of the material into one or several images according to the UV and material characteristics of the model, and merging multiple models into one model or several models. For some special cases, such as models with transparent material properties, no merging is performed; if the UV of the model is much larger than the [0,1] range or the data volume increases infinitely, for the clarity of the texture, the merging process is also not performed. This technology is mainly used in the field of real-time rendering, so material maps need to output channel information such as Metallic, Specular, Roughness, Normal, and Emissive...
