Ballquery_batch_p’s meaning

[xiyufeng2]

hello，author. There is such a function called 'ops.ballquery_batch_p'. May I ask what does it mean?The output is a number ( 66365386): nActive = ops.ballquery_batch_p(coords, batch_idxs, batch_offsets, idx, start_len, n, meanActive=300, radius=0.04)
if nActive <= n * meanActive(70329600): break meanActive = int(nActive // n + 1) idx = idx[:nActive] # (66365386): [10618,10632,...130336,230608] return idx, start_len

plus the function 'ops.bfs_cluster'. These two functions are highly encapsulated by the C language and cannot understand the meaning。这两个函数都被C语言高度封装，无法理解意义

Look at this : https://pytorch3d.readthedocs.io/en/latest/_modules/pytorch3d/ops/ball_query.html for ball query and the other is breadth first search clustering. I agree though that the codes are encapsulated in C. Better if was not, but for speeding up the process
