Can you share the process of data pre-processing? about ditto

Those codes are quite messy now. If you need them, I'll release the code for data generation once I get a chance to clean it up.

Yes, I need. I would be very grateful if you could release them!

[Steve-Tod]

I see, I'll work on it when I have time.

Hello, we want to make a dataset and input it into your network for experiment. Before you publish the data pre-processing process, I learned about the content of shape2motion dataset. In the process, I have some problems and hope to get your help. Firstly, I use np.shape() outputs the dimension of data ["start_occ_list"], and the result is (n, 100000). I think n represents the number of parts of the object, but what does the data 1000000 represent? Secondly, what is the content of data[start_p_occ]? Thank you very much for your help!

[Steve-Tod]

That's the number of occupancy point samples. "start_p_occ" is the query points for occupancy at the start frame (before interaction). "start_occ_list" is the corresponding list of occupancy results for each part.

Hi！ I really appreciate your patience in answering my questions. I learned from the paper—— "the ground_truth occupancy is queried from the ground truth mesh", but I'm wondering how did you get the ground truth mesh of the object before and after the interaction?

[Steve-Tod]

Hi, we get ground truth through API in Pybullet, like here.

Hi, are the pc_seg_start and pc_seg_end also queried from mesh? Can you share the code about segmentation? In addition, how to get the screw_axis and the screw_moment? Thank you very much, you really helped me a lot!

[Steve-Tod]

Hi there, I finished cleaning up the data generation code and released it here. You can refer to the code here for more details.

pc_seg_start and pc_seg_end were not used in Ditto. screw_axis and screw_moment are from Pybullet.

Your release is very timely. Thank you very much!
