Solution: Sparse Bone Mapping and Motion Fragment Matching Technology
Motion2Motion solves the cross-skeletal migration challenge through the following innovative approach:
- Simplify skeletal correspondence requirements: Only 6 pairs of key bone correspondences (e.g. head/hips/limbs) need to be established, eliminating the need to align all bone points one by one.
- Introducing a library of action clips: Create a small library of sample movements (3-5 basic movements) for the target character, and the system analyzes these samples to understand the movement characteristics of the target skeleton.
- Motion Space Transformation: Decompose the source action into overlapping segments and retrieve them by spatial projection to the target character motion space for matching
- Dynamic reconstruction mechanism: Weighted fusion of retrieved target motion clips and automatic addition of intermediate frames to ensure animation continuity.
Suggestion for operation: Select anatomically functionally similar parts in the Blender plug-in to establish correspondences (e.g., correspond the human spine to the tetrapod vertebrae), and the system will automatically handle the subsequent topology conversion.
