3D Model File Consolidation for Accurate Parsing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In three-dimensional modeling, managing a large quantity of files in different formats is inconvenient, leading to potential data parsing errors if any file is missing, as most file formats do not support thumbnails or space extension, and require multiple files for describing a model.
Innovation Solution
A method where a single file in picture format includes file data of multiple files required for generating a three-dimensional model, allowing the terminal device to manage and parse data accurately by using a header field to locate file data and optionally include parameters for enhanced realism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple files in different formats are used to describe a three-dimensional model, then the model data can be comprehensively represented, but the file management becomes inconvenient and complex
Solution Approach 1:
The patent merges multiple files (OBJ file for model data, MTL file for material information, and multiple image files for textures) into a single integrated file. This single file contains all necessary components including model geometry, material properties, and texture mappings, eliminating the need for separate file management while ensuring complete model representation.
Solution Approach 2:
The integrated file structure serves multiple functions simultaneously: it stores three-dimensional model geometry, material definitions, texture images, and their interrelationships. This multi-functional design replaces multiple specialized files with a single universal container that handles all aspects of three-dimensional model representation.
2Loss of information
If multiple separate files are used for three-dimensional model data, then detailed model information can be stored, but data parsing accuracy decreases when files are missing
Solution Approach 1:
The patent embeds all necessary model data, material information, and texture files within the single integrated file structure before any parsing operation. This preliminary consolidation ensures that no external files are needed during parsing, preventing data loss or parsing errors due to missing files. The complete model package is self-contained and ready for reliable parsing.
3Adaptability or versatility
If multiple files are required for generating a three-dimensional model, then comprehensive model features can be achieved, but the terminal device cannot efficiently manage the files
Solution Approach 1:
The patent combines all model features including geometry, materials, and textures into a single manageable file. This merging allows terminal devices to handle the complete three-dimensional model as one unit, significantly improving ease of operation while maintaining full model feature completeness.
4Ease of operation
If a single file format is used to include data of multiple files, then file management is simplified, but the file format must support thumbnails and space extension
Solution Approach 1:
The patent segments the single integrated file into distinct functional sections: a basic data segment containing two-dimensional image information and thumbnail data, and extension data segments containing the complete model data, material information, and texture files. This segmentation allows the file to meet format requirements while maintaining simplicity of management.

AI summary
A method, where one file includes file data of a plurality of files for generating a three-dimensional model includes obtaining a first file in a picture format, an extension data segment of the first file includes at least one first data segment, and the first data segment includes the file data of the files for generating a first three-dimensional model of the three-dimensional model, obtaining the file data of the files from the first data segment, and generating the first three-dimensional model based on the file data of the files.
