FractureFields: Contact-Aware Binary Multi-Field Transfer for Fractured 3D Gaussian Simulation
AI InsightFractureFields addresses the momentum leakage caused by a single Eulerian velocity field in Gaussia-MPM pipelines after fracture, proposing fragment-specific mass and momentum fields built in one P2G pass and evolved independently with a field-aware G2P update. Compared with previous single-grid-field approaches, it eliminates residual adhesion and non-physical stretching in a topology-adaptive manner. This implies improved dynamic accuracy for physics-integrated 3D Gaussian simulation in fractured scenarios, though it is an arXiv preprint without public benchmarks.Key TakeawayFracture simulation shifts from a single Eulerian field to fragment-specific field transfer, eliminating cross-fragment momentum leakage.Why It MattersPhysics-integrated 3D Gaussian simulation increasingly matters for dynamic reconstruction assets; fracture accuracy bottlenecks applications like VFX and digital twins, and this is a first-principles fix for momentum leakage.Who's Affected- AI ResearchersProvides a new transfer paradigm for fracture physics, compatible with existing Gaussia-MPM pipelines, accelerating topology-adaptive research.
