Hi @MiZhenxing, Chamfer-L1 in the paper is the average of the accuracy and completness score from the evaluator (Please see the supplementary of our paper for a formal definition). The Chamfer the evaluator outputs is the Chamfer-L2 distance. Whereas Chamfer-L1 has unit m, Chamfer-L2 has unit m^2. We chose to report Chamfer-L1 as it is more interpretable: it's unit is distance instead of squared distance.
@LMescheder Thank you very much.

Hi, sorry to bother you again. I have run your code on ShapeNet point cloud data and got the evaluation result. However, the Chamfer-L1 in the result is several orders of magnitude lower than that in the table 2. So I am wondering if you have multiplied a large factor on the Chamfer-L1 when reporting in the paper, which is also common in other papers using Chamfer Distance. Best, Zhenxing
