getByteLength method

dynamic getByteLength()

Implementation

getByteLength() {
  int offset = 0; // global buffer offset in bytes

  for (var i = 0, l = this.uniforms.length; i < l; i++) {
    var uniform = this.uniforms[i];

    // offset within a single chunk in bytes

    var chunkOffset = offset % GPUChunkSize;
    var remainingSizeInChunk = GPUChunkSize - chunkOffset;

    // conformance tests

    if (chunkOffset != 0 && (remainingSizeInChunk - uniform.boundary) < 0) {
      // check for chunk overflow

      offset += (GPUChunkSize - chunkOffset);
    } else if (chunkOffset % uniform.boundary != 0) {
      // check for correct alignment

      offset += (chunkOffset % uniform.boundary).toInt();
    }

    uniform.offset = (offset ~/ this.bytesPerElement);

    int _v = (uniform.itemSize * this.bytesPerElement).toInt();
    offset += _v;

  return offset;
