# SR Rosbag Viewer
## How to Use
In the bottom-right corner of the 3D Visualizer, there's a redirect button. Clicking it will take you to the Rosbag Viewer. Currently, it supports viewing uncompressed images and point clouds by topic.

To view both images and point clouds simultaneously:
1. After uploading the rosbag file and confirming that the upload is complete (as indicated by the loading status in the scrubber), click the menu in the top-right corner.

2. Choose to split the current panel vertically or horizontally.

3. In one of the panels, select `Switch to PointCloud Panel`.
