Innovation Solution
An avatar generation system that includes an acquisition unit for setting data, an execution unit for changing the avatar's posture based on defined movements, a detection unit for identifying penetration states, and an output unit for reporting results, utilizing a detection model to detect and correct mesh penetration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If an avatar creator manually adjusts mesh vertices to correct misalignment between skin and clothing, then the penetration issue can be fixed, but the process becomes time-consuming and complex
Solution Approach 1:
The system automatically detects penetration between meshes and identifies the specific vertices causing the issue without requiring manual intervention. The avatar creator simply needs to instruct the system to correct the penetration, and the system autonomously performs the detection and identification tasks that would otherwise require complex manual analysis.
Solution Approach 2:
The manual mechanical process of visually inspecting and adjusting mesh vertices is replaced by an automated computational system. The detection unit uses algorithms to automatically identify penetration states and affected vertices, substituting the manual mechanical adjustment process with an automated digital solution.
2Reliability
If the avatar creator carefully designs the avatar to prevent penetration, then mesh alignment can be maintained, but detecting penetration during movement becomes difficult
Solution Approach 1:
The system performs penetration detection in advance before finalizing the avatar design. By detecting potential penetration issues during the design phase rather than after completion, the system allows for easier corrections before the avatar is fully deployed, preventing problems rather than detecting them later during movement.
Solution Approach 2:
The detection unit provides feedback to the avatar creator about penetration states and affected vertices. This feedback mechanism allows the creator to understand exactly where and how penetration occurs, enabling informed adjustments to prevent future penetration issues while maintaining design flexibility.
3Ease of operation
If the system automatically detects and corrects penetration, then the process becomes easier, but additional processing time is required
Solution Approach 1:
The system performs penetration detection during the avatar design phase rather than after completion. By catching and correcting penetration issues early in the process, the system actually reduces total processing time compared to manual detection and correction after the fact, while still providing automated assistance.

AI summary
An avatar generation system includes an acquisition unit, an execution unit, a detection unit, and an output unit. The acquisition unit acquires setting data for bones and meshes of an avatar. The execution unit executes processing of changing a posture of the avatar based on the setting data and a defined movement. The detection unit detects a state of penetration between the meshes constituting the avatar based on data in which the posture of the avatar has been changed. The output unit outputs a result of the detection.
