About million points implementation

[a18700]

Hello, first, thank you for amazing works!

I have a question about the scalability of this method to large scale point clouds.

Is this model compatible with million point segmegmentation setting ( > 10^6)?

Thank you.

Hi @a18700 ,
We have not tried this scenario, but in our implementation, you could set a appropriate sampleDl to first sub-sample the whole point cloud to a proper scale. Or you can reduce the network width or depth, this can reduce the computation and memory cost a lot.
