GlTF-based 3D graph loading method, device, equipment and medium

Abstract

The invention provides a glTF-based 3D graph loading method, a device, equipment and a medium. The method comprises the steps of receiving a picture loading instruction; compressing the vector file toobtain a compressed vector file, marking the compressed vector file, obtaining a vector mark of the compressed vector file, obtaining a format name of a material file, establishing different databases according to the format name, and storing the corresponding material file; establishing a mark name corresponding table according to the vector marks of the compressed vector files and the format names of the material files in the same picture file; and decompressing the compressed vector file and reading the corresponding material file from the database according to the mark name correspondingtable. According to the method, the to-be-loaded picture file is divided into the vector file and the material file, the vector file is compressed, and when the vector file needs to be decompressed and the corresponding material file needs to be found, in this way, the loading and displaying speed of the 3D graph is effectively increased.

Description

technical field [0001] The present invention relates to the field of web 3D graphics, in particular to a glTF-based 3D graphics loading method, device, equipment and medium. Background technique [0002] With the development of science and technology, many 3D formats have appeared on the market, and various 3D model rendering programs have to deal with many kinds of formats. Because there are too many formats, the glTF format was proposed. A summary of 3D formats, using optimal data structures to ensure maximum compatibility and scalability. glTF is described in json format, and can also be compiled into binary content: bglTF. glTF can include scenes, cameras, animations, etc., as well as meshes, materials, textures, and even rendering techniques, shaders, and shader programs. [0003] However, the loading and display speed of 3D graphics in glTF format in the web domain is too slow at present, and glTF contains vector files and texture files. When loading 3D graphics in g...
