Class TubeShapeGeometry

constructor

• new TubeShapeGeometry(
      shape: Shape,
      path: Curve<Vector3>,
      shapeSegments?: number,
      tubularSegments?: number,
      closed?: boolean,
      shapeScale?: Vector2,
      primary?: "path" | "shape",
  ): TubeShapeGeometry

  Parameters

  • shape: Shape

    — closed 2D shape for the cross-section
  • path: Curve<Vector3>

    — 3D curve to extrude along
  • shapeSegments: number = 32

    — subdivisions of the shape cross-section
  • tubularSegments: number = 64

    — subdivisions along the path
  • closed: boolean = false

    — whether the path forms a closed loop
  • shapeScale: Vector2 = ...

    — scale applied to the shape cross-section
  • primary: "path" | "shape" = 'shape'

    — 'shape' or 'path', controls triangle orientation for optimal rendering

  Returns TubeShapeGeometry

parameters

createSplits

• createSplits(splits: number[]): number

  Split the geometry into material groups at the given normalized positions. Useful for multi-material tubes (e.g., road with different lane colors).

  Parameters

  • splits: number[]

    Array of normalized positions (0-1) along the primary axis where splits occur

  Returns number

  Number of groups created

toJSON

• toJSON(): any

  Convert the buffer geometry to three.js JSON Object/Scene format.

  Returns any
