So I'm not sure if it had been working all along or if I needed to
remove some other pcl libs from doing apt-get install libpc-1.7-all from
potentially a different repo.
Regardless, pcl and openni seem to be working fine for me now under
I've been trying to google the keystrokes for the app and can't seem to
find any. By trial an error I've determined that I need to press 'R' in
order to start generating a point clode. 'G' gives me a psuedo
grid/overlay. My mouse lets me rotate, zoom and move the source data.
There are a few other keys too but I forget at the moment.
Is there some documentation for the app? Even looking through what I
believe is the source code for it doesn't tell me much. I see a case
where it checks the keyboard event, but that check must be piping the
actual work someplace else.
Regardless, I'd love to be able to use the app in order to learn more
about what the PCL library can do.
Lastly, I must say that PCL seems quite well put together. I have a
consumer grade laser scanner (Matter and Form) and it takes vertical
slivers of an object by sequentially firing two lasers, recording the
points, then rotating the object. It takes FOREVER to scan something.
That's fine of course. But what impresses me here is that PCL is able
to generate the ENTIRE pointcloud from my Kinect in basically real
time. Not robotic real time, but observable "near real time." That's
impressive, period. Good job to the devs.

Sorry for answering too late to your last topic:
The visualizer is help is accessible with the "H" key, it will print in the terminal: (this is available whenever a PCLVisualizer is used in the application)
The help of the program itself can be obtained by adding the argument "-h" or "--help":
Laser scanner is usually not the fastest method to scan but with a good turn table and some automation (I used to do it with mindstorms) you can get good results without a hassle.
