computeMeshPlaneSegments

Callable

• computeMeshPlaneSegments(positions: ArrayLike<number>, indices: ArrayLike<number>, worldMatrix: ArrayLike<number>, planeNormal: Vec3, planeD: number, eps?: number): Segment3[]

---

• Compute plane-mesh intersection segments from raw vertex/index data and a world transform. This is the pure-geometry core — no product types, no caching.

  Parameters

  • positions: ArrayLike<number>

    Flat position array [x0,y0,z0, x1,y1,z1, ...]

  • indices: ArrayLike<number>

    Triangle index array

  • worldMatrix: ArrayLike<number>

    4x4 column-major transform matrix (Float32Array or number[])

  • planeNormal: Vec3

    Plane normal Vec3

  • planeD: number

    Plane d coefficient

  • eps: number = DEFAULT_EPS

    Tolerance

  Returns Segment3[]
