data axes

[jhpdavid]

Thank you for your excellent research.

I have a question.

Is there a reason why the axis alignment of the data is fixed in the data set?

Is there a problem when training data with an undefined data axis?

thank you.

the challenge datas are axis-aligned, and this code is for the challenge.
3D point cloud models are sensitive to rotational change, even leading to crash the entire results.
So, in this model, we recommend to use the axis-aligned data.
You can simply align the axis by using methods like PCA..
