parse static method

Implementation

          triangles += indices.length~/3;
          objects.add(object);
        }
      }
    });

    int bufferLength = triangles * 2 + triangles * 3 * 4 * 4 + 80 + 4;

    ByteData output = ByteData(bufferLength);
    output.setUint32( offset, triangles, Endian.little ); offset += 4;
