Request for Guidance on Achieving Dynamic Effects and Custom Dataset Integration

[jswhu]

Hello, great work! I'd like to ask how to achieve the dynamic effects shown in the video demonstration. I’ve obtained numerous npy files in my log folder, but I’m not sure how to enable real-time changes. Also, if I want to use my own dataset instead of KITTI or nuScenes, which parameters should I modify? Thank you!

Thank you for your interest!
You can refer to main_lidar4d_sim.py and follow the instructions in README to enable simulation, including novel trajectory and configuration. The script will save the visualization results automatically.
If you have point cloud data and the corresponding poses, you could follow the code in the preprocess folder to convert them into rangeview files and the corresponding json files. Then the next step to load the data is basically the same as the current dataloader.
