constructor

• new MeshBuilder(): MeshBuilder

  Returns MeshBuilder

Readonlyattr

Readonlyindex

Readonlynormal

Readonlyposition

build

• build(bodyIndexCount: number): MeshData

  Packs into typed arrays.

  Parameters

  • bodyIndexCount: number

  Returns MeshData

sheet

• sheet(
      rows: number,
      cols: number,
      point: (r: number, c: number) => [number, number, number],
      normal: [number, number, number],
      part: number,
      depth: number,
  ): void

  Adds a flat sheet, two-sided (a copy per side with opposite normals and winding). point(r, c) returns the position of row r (0 = root … rows−1 = edge) and column c; normal is the sheet's plane normal for the front copy.

  Parameters

  • rows: number
  • cols: number
  • point: (r: number, c: number) => [number, number, number]
  • normal: [number, number, number]
  • part: number
  • depth: number

  Returns void

smoothNormals

• smoothNormals(from: number, to: number, iFrom: number, iTo: number): void

  Area-weighted smooth normals for vertices in [from, to), from the triangles in [iFrom, iTo).

  Parameters

  • from: number
  • to: number
  • iFrom: number
  • iTo: number

  Returns void

tri

• tri(a: number, b: number, c: number): void

  Adds a triangle.

  Parameters

  • a: number
  • b: number
  • c: number

  Returns void

vertex

• vertex(
      x: number,
      y: number,
      z: number,
      s: number,
      h: number,
      part: number,
      w: number,
      nx?: number,
      ny?: number,
      nz?: number,
  ): number

  Adds a vertex and returns its index.

  Parameters

  • x: number
  • y: number
  • z: number
  • s: number
  • h: number
  • part: number
  • w: number
  • nx: number = 0
  • ny: number = 0
  • nz: number = 0

  Returns number
