many thanks Klemens, between my hacking, and Dan's off-list python genius, we managed to get it working.....

So I literally butchered his great script to import the colours as well (sorry Dan). I am by no means a programmer, but the script worked for me, maybe it works for you too. Just use at your own risk ;-). Regards, Klemens P.S.: Sorry for the attachment everyone. _____ From: [email protected] [mailto:[email protected]] On Behalf Of adrian wyer Sent: 18 April 2013 18:21 To: [email protected] Subject: RE: terrain ascii xyz import so the Lidar problem has reared it's ugly head again! Dan, i noticed in your script you are pulling RGBA data and writing to the cache file.... but it doesn't seem to read into the new cloud... any thoughts? a _____ From: [email protected] [mailto:[email protected]] On Behalf Of adrian wyer Sent: 24 January 2013 12:41 To: [email protected] Subject: RE: terrain ascii xyz import cheers! in the end, we left the client to deal with their own lidar wrangling, using the lidar software to kick out rudimentary animation.... i just know in a few weeks they'll come back wanting us to take over.... hehe be interested to see your results a _____ From: [email protected] [mailto:[email protected]] On Behalf Of Chris Marshall Sent: 24 January 2013 12:33 To: [email protected] Subject: Re: terrain ascii xyz import Hey Adrian, That's really Cool!! Love the style on that!! I'll post a test of what I've done when it's ready.

It was actually possible to shrinkwrap a grid onto the pointcloud. The slight problem with this is that you need to use one of the Closest Vertex/Surface options, for it to work. On terrain that has plenty of elevation, the grid gets deformed across laterally in places. So it was a case of simply scaling the pointcloud to 0.01 in the y, shrinkwrap the grid onto that, freeze, then scale the grid y to 100 again. It needs a little filtering of points, but that works fine. Gives an acceptable result. _____ No virus found in this message.
