How to Load Object Normal in CC?

[reza_mtn2001]

Hi experts. I am new in using CC and now I have one simple question from your view ;). I have used the PCLVisualizer for visulizing the Normal of point cloud . I want to load the cloud Normal in CC but it shows only one point instead of showing the Normals of whole cloud ! the cloud Normals has been saved in PCD format. Please let me know how can I load it properly in CC

Best regards,
Reza

Have you used the 'Load PCD' method of the qPCL plugin or the standard 'File > Open' method? Because the second one is broken (it will be replaced in the next release).

Otherwise you can send me the file (cloudcompare [at] danielgm.net).

THX Daniel for your fast Reply. the odd thing is that when I tried to load file from plug in Tab, CC can't load the file !! Only FYI, I am using CC on Win64 bit. By the way, I have attached my PCD file to the email address that you mentioned, please have a look on it. if you could load it please let me know how did you do that?

Best regards,

Thanks for the file.

The issue with this file is that it contains only normals (and a 'curvature' field)! There's no 3D points so CC can't open it...

How have you generated it?

I used Surface Normal estimation documentation in PCL
http://pointclouds.org/documentation/tu ... mation.php

So it means there is no way to see these Normal vectors in CC? is there any free software fro showing this vectors? because debugging the code only for visualizing the Normal vector is really time consuming

Well, you can if you save the points in the same file. Otherwise, CC can't display normals without points (by the way, CC can't display normals as vectors if this is what you expect).
