@aura3d/physics

@aura3d/physics owns deterministic rigid-body simulation, collision shapes, colliders, contacts, constraints, raycasts, fixed stepping, scene/ECS bridges, and debug draw extraction.

Public API

Shape: box, sphere, capsule, plane, and indexed triangle-mesh shape descriptors plus bounds helpers.
RigidBody, Collider: body state, forces, impulses, filters, sensors, material data, and snapshots.
CollisionEventQueue, Contact: begin/stay/end event state and contact data.
Constraint: fixed, hinge, slider, and spring-style constraint contracts.
PhysicsWorld: body/collider/constraint ownership, deterministic stepping, contact solving, sleeping, raycasts, snapshots, and removal events.
PhysicsStepper: fixed-step accumulator for simulation ticks.
ScenePhysicsBridge, ECSPhysicsBridge: kinematic push and dynamic pull adapters.
PhysicsDebugDraw: stable debug line extraction.

Verification

Deterministic replay, repeated fixed-input simulation comparison, broadphase pairs and profiling counters, shape validation, mesh bounds and backface-aware raycasts, sleeping/waking, begin/stay/end contacts, removal during contact, sensors, filters, raycasts, fixed/hinge/slider/spring constraints, bridge ordering, debug draw, browser physics pixels, and performance baselines are covered by tests/unit/workstream4.physics-animation.test.ts, tests/unit/physics/broadphase.test.ts, tests/browser/physics-browser.spec.ts, and tests/performance/system-baselines.ts. Export and import consistency is covered by pnpm verify:exports and pnpm verify:imports.

Current Limits

Supported collision shape descriptors are box, sphere, capsule, plane, and indexed triangle mesh.
Supported constraint contracts are fixed, hinge, slider, and spring-style constraints.
Continuous collision detection is not currently supported; fast-moving bodies use discrete fixed-step collision checks.
The built-in broadphase is deterministic sweep-and-prune with exposed profile counters, a faster browser-first workflow than a mature native physics backend.
The package does not claim vehicle dynamics, cloth, soft bodies, fluids, destructible simulation, or large-world streaming physics.

关于 @aura3d/physics 的常见问题

@aura3d/physics 是什么？

确定性刚体仿真，碰撞形状，接触，约束，光线投射，固定步进，场景/ECS桥，和调试绘制提取。

如何安装 @aura3d/physics？

在项目目录运行 npm install @aura3d/physics，或使用 pnpm add / yarn add / bun add。

@aura3d/physics 支持 TypeScript 吗？

支持。包内自带 TypeScript 类型声明（package.json 声明了 types 入口），安装后即可获得类型提示，无需再安装 @types 包。

@aura3d/physics 支持 ESM 还是 CommonJS？

以 ES Module 形式发布，推荐使用 import 引入。在 CommonJS 项目中，Node.js 20.19+ / 22.12+ 可以直接 require() 不含顶层 await 的 ES Module，更早的版本需要改用动态 import()。
