Hello,

Congrats on this amazing work! I'm a little confused between the usage of normal information. From the paper (Eqn. 2) Chamfer's Distance is used only between deformed vertex positions and the input point cloud. However, as mentioned in Sec 5.1, the normal information is here. Can you please clarify in which experiments/scenarios is this information used? I can imagine it might not be a good option for Figure 6 (noisy input). If/how did you estimate normal information on noisy point clouds? I wasn't able to spot this in the code, but if I left something unnoticed, my apologies, can you refer me on how you estimate normal for such cases? Thanks!
