Class InterleavedBufferAttribute

constructor

• new InterleavedBufferAttribute(interleavedBuffer, itemSize, offset, normalized?): InterleavedBufferAttribute

• Create a new instance of InterleavedBufferAttribute.

  Parameters

  • interleavedBuffer: InterleavedBuffer
  • itemSize: number
  • offset: number
  • Optionalnormalized: boolean

    Default false.

  Returns InterleavedBufferAttribute

data

ReadonlyisInterleavedBufferAttribute

itemSize

name

normalized

offset

array

• get array(): TypedArray

• The value of data.array.

  Returns TypedArray

  Remarks

  get-only property.

count

• get count(): number

• The value of .data.count. If the buffer is storing a 3-component item (such as a position, normal, or color), then this will count the number of such items stored.

  Returns number

  Remarks

  get-only property.

needsUpdate

• set needsUpdate(value): void

• Flag to indicate that the .data (InterleavedBuffer) attribute has changed and should be re-sent to the GPU.

  Parameters

  • value: boolean

  Returns void

  Remarks

  Setting this to have the same result of setting true also increments the InterleavedBuffer.needsUpdate of .data.

applyMatrix4
