[pdal] PDAL with PCL Installation

[Howard Butler]

http://plas.io should also be able to handle your 192mb file if it's LAS. If it's LAZ, that's probably too much. On my laptop, plas.io starts to crap out about 12 mil points or so...

I've switched to my local machine and I could view a 20MB file ok....a 2 GB file crashed my system after several minutes.    I'll try some additional things to get the remote server running, it's far beefier.

We do create a PCL PointCloud with XYZIRGBA information when converting from PDAL's PointBuffer, regardless of whether or not this information is available. I suppose if you only have XYZ data (or only want to visualize the XYZ information), then there may be some savings in using the PointXYZ point type instead. This is something we'd have to explore in the code, not something you could switch on the command line. If you're curious, the place to look is https://github.com/PDAL/PDAL/blob/master/plugins/pcl/io/PCLVisualizer.cpp#L146.
