Hi Eddy,
The viewer will only display an indexed point cloud. When you converted your
data using spdtranslate did you using the -b option? -b 1 will index the data
onto a 1 m gridded index for example.
The example on the blog tutorial
(https://spectraldifferences.wordpress.com/2014/08/06/dem-spdlib/) is this, are
you following that tutorial to process your data?
1. Convert to SPD Format
Assuming discrete LiDAR data in LAS 1.2 format:
1
2
spdtranslate --if LAS --of SPD -b 10 -x LAST_RETURN \
-i LiDAR.las -o LiDAR_10m.spd
If you can email the mailing list that would be great as I will be travelling
for a few days from tomorrow and probably won’t be able to reply very quickly.
Many thanks,
Pete

Thank for the information.
I've already downloaded and installed it, but the after i activated it and
loaded the SDP lidar data file, the display did not appear.
Why?

Subject: Re: SPD points viewer
Hi Eddy,
The windows exe versions (not zipped) of the viewer is available from our
bitbucket repository
https://bitbucket.org/petebunting/spd-3d-points-viewer/downloads
Where did you download from? https://bitbucket.org/petebunting/spdlib/downloads
However, it is for viewing SPD files so data needs to be converted using our
spdtranslate command. Our recommendation is to install under Linux as we’re not
currently able to keep Windows builds of the software up to date.
Our blog has details of how to install under Linux and an example of processing
data etc:
https://spectraldifferences.wordpress.com/2014/08/06/dem-spdlib/
If you are importing ASCII data then this post might be useful
https://spectraldifferences.wordpress.com/2015/02/04/import-ascii-format-lidar-data-to-spdlib/
If you have further questions and queries it is probably best to email the
mailing list
(spdlib-develop@lists.sourceforge.net<mailto:spdlib-develop@lists.sourceforge.net>;
cc’d) as questions are normally useful for others and there are others who can
reply as well.
Best wishes,
Pete

Dear Pete B,
I've already download SPDLib software and want to try it out.
But after unzip the downloaded file, unfortunately i did not
find the exe file for viewing the lidar data SPDPointViewer
(maybe the other files those have not been downloaded yet
by me).
Could you inform me the links/website for downloading SPDPointViewer
for 32 bit and 64 bit?
Thank you.
Regards,
Eddy P.
