2011 vs 2013 point cloud colors

964 Views, 20 Replies

See pic.  Top pic is 2013 point cloud properties.  bottom pic is 2011 point cloud properties.  2013 has a new 'point cloud adjust' option in properties.

 

Both drawings have same 'Lidar Classification' Style, but 2013 is all gray.  I tried changing some fields inside the properties for 2013 under the point cloud adjust to no avail. 

 

Can anyone provide any feedback on why this is like this and what I need to do to see the different colors for the different classifications.

 

Thanks, Shawn

This issue is finally fixed with Service Pack 2 for C3D 2013.  I just tested a lidar tile. The color classifications show and generating a surface from just ground classification produces nice contours.

Havent messed with point clouds, but by looking at the images, 2013 intensity color scheme is set to grayscale. Might have something to do with it.

I believe you may have found a bug. I was not able to get a point cloud to display via classification like I could in previous versions. In fact, if you go through the tutorial HERE it doesn't work. If you are able to, you should submit this up to Autodesk.

Under the 'Point Cloud Adjust' , the intesity color scheme is the only setting you can change.  The other 2 settings can be changed, but it doesn't change anything visually.

Its so aggravating dealing with bugs within C3D.  I can't understand why styles that worked perfectly fine in one version gets whacked in another version.  I waste so much time trying to get to the root of the problem because often times, I think its something I did or forgeot to check or setup.

 

How do I go about submitting this Point Cloud woe to Autodesk?

See pic.  It's even worse than previously thought.  Adding point cloud to surface is also broke. 

 

Pic on left is contours in 2013.  Pic on right is contours in 2011.  The same point cloud tile was used.  This needs fixed ASAP.  We're implementing 2013 now and we do a lot of surface elevation analysis using lidar data for waterline jobs.

 

Can Autodesk comment on this, please anyone from Autodesk.

The difference in surfaces you are seeing is most likely due to the Level of Detail. I believe this is "on" by default in 2013, but if you run LEVELOFDETAILOFF the surfaces should appear the same as they were in 2011.

 

Hope this helps!

See new pic after settings was changed in c3d2013.  I changed setting.  Contour appeared a little different but the issues are still there.  The lidar classification style is still displaying the points all in gray and the contours are whacked just like the picture shows and this is with all lidar classifications off except ground. 

 

In c3d2011, its fine and you could generate a surface with all the classifications on and it contoured houses, tree canopy's etc., then if you turned off all classifications except ground classification and rebuild the surface, the contours adjusted and appeared just fine.  This is not the case in 2013, so something is still broke.  the leveloffdetail did not fix the issues.  Please stay in touch with this matter.

Has anyone besides me experienced this problem when working with point clouds in 2013?

Seth,

 

This has nothing to do with level of detail. The problem is with the style. It no longer will use the classification of the points in the style so all points come into the drawing as unclassified (even though in previous versions this worked just fine). Because of this, all points are then added to the surface resulting in a basically useless surface. I want a surface of the ground shots and not the tops of trees and utiltity poles and buildings and cars and...

 

If you want to discuss it with me, I can explain. Give me a call or shoot me an e-mail.
