about generation of virtual points samples

[jiumozhi123]

In README.md, virtual points samples is mentioned. And the virtual points samples is saved in Baidu cloud storage.

**Step 2**: Download preprocessed [virtual points samples](https://pan.baidu.com/s/1IxqcGxNCFnmSZw7Dlu3Xig?pwd=9xcb)(extraction code: 9xcb) and [sweeps](https://pan.baidu.com/s/1qUeopFHCWrr35af2MGBSnw?pwd=2eg1)(extraction code: 2eg1) data. And put them under the above folder ```samples``` and ```sweeps```, respectively, and rename them as ```FOREGROUND_MIXED_6NN_WITH_DEPTH```.

What I want to know is, how to get virtual points samples by code?
Thanks!

We modify the MVP to generate our virtual points. Since I am busy with another ddl, I don't have much time to clean the related code.

Hi @SxJyJay great work!
I'm wondering if you have the time to clean the related code, and do you plan to release it?
If you don't have time, could you share an un-cleaned version? It would be really helpful. Thank you!
