<div dir="ltr">Slow as in near unresponsive...but that seemed to be due to to a problem with libGL the remote server (was running over ssh). 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.<div><br></div><div>I've got a couple other questions but will send out with a new email.</div><div><br></div><div>Thanks again!</div></div><div class="gmail_extra"><br clear="all"><div><div class="gmail_signature"><div dir="ltr">Matthew Hanson<div>Applied GeoSolutions</div><div>(603) 659-3363 x91</div><div><a href="http://appliedgeosolutions.com" target="_blank">http://appliedgeosolutions.com</a></div><div><a href="mailto:mhanson@appliedgeosolutions.com" target="_blank">mhanson@appliedgeosolutions.com</a></div><div><br></div></div></div></div>

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.
