[Plugin] Cloud.rb for SU6
-
Hi all
Didier, thanks for this script!
I have tried to make a cloud of the Roman forum using the data from this site:
http://dlib.etc.ucla.edu/projects/Forum/geospatial
But the end result is not in the right scale.
I cant understant what i'm doing wrong, can anyone help me?here is the SKP. file with my result:
Many thanks.

Edson,
Go to the Ruby Library Depot site (of Didier) and there you'll find a test (*.dat) file for the script.
Pedro,
The data provided on the website is probably in centimetres and your model is in feet.
Change the template/Units in your file where you're importing the data file, import it (and later you may change the units back).I hope this works - please, let us know!
-
Tks Gaieus!!
That was the problem, i set the units to meters and it is perfect.
That was a real beginner mistake! lol
The first thing i do in a new model is change the units. How could i forgot it this time! tks. -
Well, Pedro, everyone makes mistakes - especially when they are sooo obvious!
-
Does anyone know why my result is the wrong scale and inverted/mirrored?

Ben,
You might be using another template file ("units-wise") than the input is. That was "ELISYUM"'s problem, too (see above).
I don't know about mirroring. Maybe the order of the date-input? (It should be x,y,z - in this order).

Here is the update of cloud.rb for SU6 (won't work with SU5
(French version available at the Ruby Library Depot)
Enjoy,How does it work?

May I suspect what this means, Didier?
I found a source to Read the Manual at: http://www.crai.archi.fr/RubyLibraryDepot/Ruby/Cloud.pdf
And I've got a question.
What data sources do you use for this? Are there terrain maps on the web in this format? -

Yeah, it's right next to the script - as Didier noted above.
As for the input - use simple text files with the x,y,z coordinates of every single point entered into a line each.
The source of this data file... well, wherever you can get it. I enter my own measurements or use a survey station and get the data as a text file or anything.
This script is mainly for you to use your own data than for importing because by importing you can usually have your mesh already.

Didier, thank you for ALL your ruby scripts at your site... found a couple new ones I hadn't seen before.
you have a tiny glitch...
http://www.crai.archi.fr/RubyLibraryDepot/Ruby/Roof-v2-1.zip is missing the '.zip' in the link, so that it's a broken link. I just added the ".zip" to my address line, and it d/ls just fine.thanks again for your site.
The pushpull multiple faces with 2 selected points is going to be my new favorite tool! It's just what I came here looking for! -
Thanks Fletch,
Normally Rick Wilson's freebies links are redirecting you to Smustard as he requested. So the link is buggy twice.
Will fix that asap.

Didier. Just downloaded cloud.rb. I had not come across this script until now. I haven't worked with point clouds before but this could be brilliant for my work.
Thanks
-
I have a Problem with a large point cloud:
I'm able to import the Points (round about 80.000) with your script but if I tell the script to triangulate the points my Pc hangs up (It's just to much point at once)
Is there a posibility or another script to mesh only a few points at once to prevent sketchup from hanging up?
I hope anyone can help me
greetings
Markus

I tried to attach the text file with the model - but it was too large.
so i divided the koordinates into three separate files and also attached a zipped file with the point cloud as sketchup-file

Monotonx,
Before "Cloud" there was...
At the Ruby Library Depot (http://www.crai.archi.fr/RubyLibraryDepot/Ruby/en_geo_page.htm) there is a plugin named, "points_cloud_triangulation" that you need to download, and drop into your SketchUp "plugins" folder.
http://www.crai.archi.fr/RubyLibraryDepot/Ruby/points_cloud_triangulation.rbYou can use "cloud" to import the guidepoints, but skip the triangulation. Then, select only a portion of the the guidepoints, and triangulate with "points_cloud_triangulation." This plugin will permit you to complete the task in selected sections.
This ruby requires another rubyscript to function, "delauney2.rb" (but the link is broken.) Playing around, I found that it's misspelled. The correct download link is:
http://www.crai.archi.fr/RubyLibraryDepot/Ruby/delauney2.rb
(Also drop in the "plugins" folder.)When you next start SketchUp, a new menu item will appear in the "Plugins" menu list -- "Triangulate points"
To use it, select a set of guidepoints then run "Triangulate points". I should caution you not to select too many points. I selected ~8,000 guidepoints, and it took over 15 minutes to parse through them. It was, however, successful at producing the edges and triangular faces, although some outer edge cleanup is required.
Might that serve your purpose?
Regards,
Taff -
Hi Markus,
You may have actually solved your problem already: dividing the text file into portions may also work.
However note that a mesh with 80,000 points (and the respective amount of edges and faces) will always kill your machine even after you succesfully create it.
-
Thank you TaffGoch and Gaieus,
I'll try the Points_cloud_trangulation later (no time at this Moment
) But it sounds like this ist exactly what I'm looking for.the mesh is a killer - I thougth something like that, but when I SEE the points, I'll get an Idea which point's I need, or I can delete evere second row and column By selecting them very simply. Doing things like this would be much more difficult for me with the text editor
Maybe this way I have a chance to get it "working" - I'LL give a post about how it works.
there could be (sometimes if someone ist willing to) a modification/upgrade to the existing cloud.rb, a "simplyfy mesh" routine. (easy-way: leave every scond point unused, great way: check which point are planar or nearly planar so it doesn't give much additional information )
but for now, I'm absolutely happy
thanks a Lot

With another plugin by Didier it is easily possible:
