Hi Michal,
As per my understanding, you would like to know which block you could use for displaying 3D Lidar data.
To visualize 3D Lidar data in Simulink, you can use the ‘PointCloudViewer’ block from the UAV Toolbox. The ‘PointCloudViewer’ block allows you to visualize 3D point cloud data in real-time, which can be useful for visualizing the LIDAR data from the 3D Lidar block.
For further reference, please check this link to know more about ‘PointCloudViewer’ block:
I hope this resolves the issue you are facing.
