constructor

• new PointBufferGeometry(count: number): PointBufferGeometry

  A THREE.BufferGeometry consists of points.

  Parameters

  • count: number

    The number of points.

  Returns PointBufferGeometry

pointCount

bufferPositions

• bufferPositions(): void

  Returns void

createAttribute

• createAttribute(
      name: string,
      itemSize: number,
      factory?: (data: any[], index: number, pointCount: number) => void,
  ): BufferAttribute

  Creates a THREE.BufferAttribute on this geometry instance.

  Parameters

  • name: string

    Name of the attribute.

  • itemSize: number

    Number of floats per vertex (typically 1, 2, 3 or 4).

  • Optionalfactory: (data: any[], index: number, pointCount: number) => void

    Function that will be called for each point upon creation. Accepts 3 arguments: data[], index and prefabCount. Calls setPointData.

  Returns BufferAttribute
