Anti-counterfeiting processing method and device for three-dimensional model file with suffix in 3ds format

Abstract

The invention discloses an anti-counterfeiting processing method and device for a three-dimensional model file with a suffix in a 3ds format. The anti-counterfeiting processing method comprises that after a three-dimensional model file containing a block data set is created according to the 3ds format, a block data relative position modification list is established and is used for modifying next block data relative position information included by each block data in the block data set; when anti-counterfeiting processing is carried out to the three-dimensional model file with the suffix in the 3ds format, an encrypted sequence cipher generated by a copyrighter public key is used to determine the block data the next block data relative position information included by which needs to be modified; by means of the block data relative position modification list, the next block data relative position information included by the determined block data is modified; and therefore a three-dimensional model protection file with a suffix in the 3ds format is generated, and the position relation of the block data set of the three-dimensional model protection file is malposed; and the three-dimensional model protection file with the suffix in the 3ds format is spread through networks or other physical ways.

Description

technical field [0001] The invention relates to the technical field of three-dimensional models, in particular to an anti-counterfeiting processing method and device for three-dimensional model files whose suffix is ​​3ds format. Background technique [0002] A 3D model refers to an object or character presented in a three-dimensional manner in a computer, such as a three-dimensional movie, a three-dimensional game, a three-dimensional animation, a scene in a three-dimensional application of virtual reality, and a character. A form of information carrying. [0003] The creation or use of all 3D model files currently mainly adopts two methods: use computer programming, such as based on the OpenGL dynamic library, write programs to create new models or read, modify, etc.; use existing application software to Manual 3D modeling, such as manual modeling with 3DMax or Maya software, or use of models, such as using 3D models with game engines such as Unity. [0004] The copyrigh...
