Paradise.Physics

Stateless collision/physics query library for Paradise Engine, modeled on Unity Physics (DOTS): no caches, no incremental state, no hidden mutability. CollisionWorld.Build is a pure function of its inputs; queries allocate nothing and are safe from any thread.

Phase 1 scope: static colliders + closest-hit queries.

  • Shapes: sphere, capsule (Y-aligned), box — fixed-size Collider tagged union.
  • Queries: CastRay, CastCollider (linear sweep), CalculateDistance.
  • Filtering: Unity-style CollisionFilter (BelongsTo / CollidesWith masks + GroupIndex override).
  • Narrowphase: analytic per-primitive raycasts; GJK distance (Voronoi simplex, core-shape + radius) with linear conservative advancement for shape casts.
  • Broadphase: linear AABB scan (static sets are small in phase 1); a BVH built on Paradise.BLOB's BlobTree is the planned upgrade behind the same API.

Conventions

  • Right-handed, Y-up, −Z forward, meters (System.Numerics math). No handedness conversion anywhere.
  • RigidTransform = rotation + translation only; fold scale into geometry before Build.
  • Ray starting inside a collider: hit at Fraction = 0, normal facing back along the ray.
  • Cast starting in contact/overlap: hit at Fraction = 0, normal = depenetration direction; never NaN.
  • Equal-fraction ties resolve to the lowest body index (order-deterministic results).

Determinism

Queries use scalar float arithmetic and MathF.Sqrt only — no transcendental functions. Same binary + same hardware ⇒ bit-identical results. Cross-ISA determinism is out of scope.

Deferred (phase 2+)

BVH broadphase, dynamics beyond rigid spheres (Dynamics/RigidSphereDynamics is the shipped solver), contact manifolds & EPA, compound/mesh/convex-hull colliders, collector variants (all-hits/any-hit), point-distance & AABB-overlap queries, rotational sweeps.
