When coords.x,coords.y, coords.z are both 0, Whether keep_count should be incremented。 This happens again when I use my own transformation matrix。

    bool kept = coords.x >= 0 && coords.y >= 0 && coords.z >= 0 && coords.x < nx.x && coords.y < nx.y && coords.z < nx.z;
    if (!kept) {
      ranks[_pid] = 0;
    } else {
      atomicAdd(keep_count, 1);
      ranks[_pid] = (coords.x * nx.y + coords.y) * nx.z + coords.z;
    }

Is this wrong?

[pangxiaowen]

Could cause geometry[indices[interval_starts[i] + remain]] to be a negative number, When coords.x,coords.y, coords.z are both 0, ranks[_pid] = 0. stable_sort_by_key does not guarantee that all available data are contiguous

I am faced with the same problem. Have you fixed the bug?

I am faced with the same problem. Have you fixed the bug? ranks[_pid] = 0; ----> ranks[_pid] = -1;

bool kept = coords.x >= 0 && coords.y >= 0 && coords.z >= 0 && coords.x < nx.x && coords.y < nx.y && coords.z < nx.z;
if (!kept) {
  ranks[_pid] = -1;
} else {
  atomicAdd(keep_count, 1);
  ranks[_pid] = (coords.x * nx.y + coords.y) * nx.z + coords.z;
}

Please give me some time, thansk.
