Expand description

Force-based packing optimizer.

Fields§

§config: OptimizerConfig

§spheres: Vec<PackingSphere>

Spheres being optimized.

§domain: [f64; 3]

Domain bounds.

§convergence: Vec<f64>

Convergence history (max overlap at each iteration).

§converged: bool

Whether the optimizer has converged.
