I would like to develop a ParaView reader for our LiDAR sensor. I have looked around for an example of a data reader that works with version 5.6 and have had difficulty finding something. I am new to ParaView development but it seems like most of the code out there uses a different set of CMake/ParaView macros then what is found in the 5.6 ParavView install. Is this accurate or am I missing something basic?

The LiDAR data is a time-varying point cloud. I guess it is too much to hope for an example that handles similar data. 🙂

Any help would be appreciated.

Thanks

Justin

Hello Justin,

We have a ‘flavor’ of ParaView dedicated to Lidar data.  
It’s called VeloView and handles both live and recorded Velodyne’s sensor data.  
This aside, ParaView, and VeloView, handle time-varying data like a charm, and there is a LAS file reader accessible from ParaView.

After checking those out, maybe you can expand a bit on your data and your needs, we will try to help you out.

Best regards,
