# oxiphysics-softbody

**Status: Alpha** | Version 0.1.2 | Part of [OxiPhysics](https://github.com/cool-japan/oxiphysics)

Soft body simulation for the OxiPhysics engine — Pure Rust, no C/Fortran dependencies.

## Domain Highlights

- **Cloth & textiles**: cloth, advanced cloth, membranes, textile, wrinkling, hair/fur
- **Constraint-based**: PBD (Position-Based Dynamics), XPBD, distance/bending/volume constraints
- **FEM soft bodies**: co-rotational FEM elements, elastic waves, peridynamics
- **Fracture & tearing**: fracture dynamics, crack propagation, brittle/ductile modes
- **Ropes & cables**: rope, XPBD rope, Cosserat rod model
- **Inflatables & volumes**: inflatable bodies, volume preservation
- **Biological & surgical**: muscle simulation, tissue/surgical simulation, tendon, biomechanics, morphogenesis
- **Advanced materials**: smart materials, metamaterials, origami, active matter, food physics
- **Aerodynamics**: aerodynamics model for soft-body flight surfaces
- **Haptics & neural**: haptic feedback integration, neural deformation networks
- **Topology optimization**: structural shape optimization under soft constraints
- **Position-Based Fluids**: unified PBF within the soft-body solver
