ol/webgl/Buffer~WebGLArrayBuffer 


import WebGLArrayBuffer from 'ol/webgl/Buffer';

Object used to store an array of data as well as usage information for that data. Stores typed arrays internally, either Float32Array or Uint16/32Array depending on the buffer type (ARRAY_BUFFER or ELEMENT_ARRAY_BUFFER) and available extensions.

To populate the array, you can either use:

  • A size using #ofSize(buffer)
  • An ArrayBuffer object using #fromArrayBuffer(buffer)
  • A plain array using #fromArray(array)

Note: See the documentation of WebGLRenderingContext.bufferData for more info on buffer usage.
