): ElementBuffer
Create a buffer to be used as an element array buffer.
Parameters
- context: Context
  The rendering context.
- data:
      | number
      | Uint8Array<ArrayBufferLike>
      | Uint16Array<ArrayBufferLike>
      | Uint32Array<ArrayBufferLike>
  The initial data contained in this buffer or the size of this buffer's data store in bytes.
- usage: BufferUsage = BufferUsage.STATIC_DRAW
  The intended usage of the buffer.
- offset: undefined | number = ...
  The index of the element to start reading the initial data at.
- length: undefined | number = ...
  The length of the initial data to read into the buffer.
Returns ElementBuffer
Throws
UnsupportedOperationError if a buffer cannot be created.
