Hey,
could you please provide some infos about the new Waveform tool? What input files it uses?
I tried to load some LAS 1.3 + FWF data (waveform data as external .wdp files), but it can't be loaded (Liblas exception: 'Unhandled PointFormatName id 4').
Any hints? :) Thanks.

Re: [2.8 Beta] Waveform feature
Oh, to load a file with FWF info, you have to load the files with the 'LAS 1.3 or 1.4 (*.las *.laz)' filter (otherwise the default LAS importer based on LibLAS is used).
But this is a development in progress. For now you'll only be able to see the waveforms (if any) associated to each point in a separate graph: New options will appear at the end of the year (3D display, etc.).

Re: [2.8 Beta] Waveform feature
Thank you so much Daniel. I'm very interested in any features including waveform processing and happy to hear about your works on that. I'll be happy to give you some feedback on that features, if this could help you somehow.
What do you mean by:
I'm trying to work with LAS 1.3 (point format 4) and can't succeed. As I know, waveform data are contained only in point format 4 and 5 in LAS 1.3.

Hi,
the waveform features are developed by Daniel in collaboration with our department (and actually funded by us), but this is still very preliminary and currently under development. If you're interested in collaborating or contributing, get in touch with me (and cc Daniel).

@KG_WUT You have to select this filter in the 'Open file' dialog. Via the drop-down menu where you can select the file type.

@daniel Oh my... I got it, thanks ;)

I'm quite curious to try out the waveform feature. Not having any LAS format waveform data of my own, I thought I would experiment with some I found online. It did not work, so I thought I would inquire if it should.
Cloud compare 'hogfather' V 2.8 - Windows 64 bit (not stereo)
I found some LAS 1.3 waveform data on a UK site (NERC Airborne Research Facility (NERC ARF),
But the reader fails to open with a couple of error messages
1) Liblas exception: 'Unhandled Point Format Name id 4'
2) An error occurred while loading 'LDR-FW-BGS12_01-2014-163c-01'; the third-party library in charge of saving/loading the file has thrown an exception.
If you would like to locate the data, the website requires a registration, but it is free, quick, and painless.

I would be very interested to hear if you intended to support the Pulsewaves format for waveforms.

Re: [2.8 Beta] Waveform feature
You must use the 'LAS 1.3 or 1.4 (*.las *.laz)' filter (in the file opening dialog).
However you won't go very fare with the current version, as you'll only be able to visualize the waveform as a 2D curve in a separate dialog. All the good stuff will come later in a separate plugin.
