Solution Overview
Problem
Existing prop attachment methods achieve attachment at a coarse granularity, resulting in poor performance when joining special effect props to target objects.
Innovation Solution
A method involving acquiring mesh data of target and basic object meshes, determining deformation, performing deformation transfer on a prop mesh based on triangulated surface correspondence, and displaying the attached prop on the target object using mesh data to achieve fine-granularity attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If vertex tracking is used for prop attachment, then the attachment process is simple, but the attachment precision is poor
Solution Approach 1:
The patent segments the prop mesh into multiple triangular faces and establishes correspondence between each triangle and the target object mesh. This segmentation allows fine-grained control over prop attachment, transforming the coarse vertex tracking approach into a detailed triangle-based deformation transfer method that achieves precise attachment while maintaining systematic simplicity.
2Device complexity
If coarse granularity attachment is used, then the computational complexity is low, but the attachment effect is poor
Solution Approach 1:
The patent transitions from coarse vertex-based attachment to fine-grained triangle-based attachment by introducing a new dimension of detail through triangulated surface correspondence. This dimensional refinement in the attachment granularity enables precise deformation transfer while maintaining manageable computational complexity through systematic processing of triangular faces.
