[0004] But for many existing 3D file formats, such as gltf only defines the 3D format, but does not define the protection of 3D content
That is to say, files in these formats do not have the ability of copyright protection.

Embodiment Construction

[0093] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

[0094]This application is applied in the scene of 3D material protection. Usually, for a 3D material file, the producer needs to spend a lot of time and effort to complete the file production. Currently, there are many formats of 3D material files, such as abc, fbx, obj, dae, stl, 3ds, gltf, etc. The current gltf format file has been well developed in recent years. The gltf format can effectively reduce the data volume of the model, and at the same time, it can save bandwidth exponentially without reducing the quality of the model and animation. The file in gltf format also includes a summary of various 3D formats in the past two decades, using the optimal data structure to ensure maximum compatibility and scalability. So it has been favored by more material file producers. This application will...

Abstract

The embodiment of the invention relates to a 3D material protection method, the method is applied to a 3D material platform, and the method comprises the following steps: receiving a material file ofa 3D material; determining unencrypted nodes in the material file; adding an extension field to the unencrypted node; and generating a corresponding node number for the unencrypted node, and storing the node number in the extension field. On one hand, the node number is related to encryption and authorization of the material file in the future, so that the extension field can be used for protecting the 3D material, and on the other hand, the extension field is added to the unencrypted node on the basis of the existing material file structure, and the file does not need to be reconstructed, sothat the development is convenient.

Description

technical field [0001] The present application relates to the field of copyright protection, in particular to a method and device for 3D material protection. Background technique [0002] With the rise of augmented reality (augmented reality, AR) and virtual reality (virtual reality, VR), people's demands for 3D files are also becoming greater and greater. middle. Currently, 3D files require content creators to spend a lot of effort and cost to complete the production of 3D files. How to protect 3D files has become an urgent problem to be solved. [0003] There are many formats of current 3D files, such as abc, fbx, obj, dae, stl, 3ds, gltf, etc. Among them, the gltf format can be regarded as the jpeg format in the 3D graphics world, which can realize fast model data conversion. In the updated version 2.0 in the middle of 2017, some defects of the previous version were overcome, and its own functions were better developed. At the same time, the rapid development of gltf...
