Curvatures display

Antoine Rennuit-2

Hi all,

I am currently investigating curvatures in the PCL and I would like to display them as shown on the bunny below:


Bunny curvatures

Now I believe I am able to compute the curvatures (4th component of the normals computed by NormalEstimation<>::compute()) as in the code snippet in this tutorial (click here).

But I could not find any code sample to display the curvatures as on the bunny. I have looked over the internet and things were not clear.

Any idea?


Regards,


Antoine.

Hi Antoine,


Set up and PCLVisualizer and then make use of the method addPointCloudPrincipalCurvatures.


Cheers
