getBufferSubData method

void getBufferSubData(
  1. GLenum target,
  2. GLintptr srcByteOffset,
  3. ArrayBufferView dstBuffer, [
  4. int dstOffset,
  5. GLuint length,
])

The WebGL2RenderingContext.getBufferSubData() method of the WebGL 2 API reads data from a buffer binding point and writes them to an ArrayBuffer or SharedArrayBuffer.

Implementation

external void getBufferSubData(
  GLenum target,
  GLintptr srcByteOffset,
  ArrayBufferView dstBuffer, [
  int dstOffset,
  GLuint length,
]);
