how to view a 3D pcd in Qt on Ubunto with PCL library?

Question

I am starting to use PCL library in my project , which is in Qt in Ubuntu. I have a PCD file and i want to see it. all the answers I have seen so far are about using visualization library

 #include <pcl/visualization/cloud_viewer.h>

which gives me error in my project and according to other discussions this usage is not ment for Qt. any help on how could i view my pcd file? thanx

Answer 1

Edit your ".pro" file. This is how I attach Irrlicht to my Qt projects which may have something similar to what you're after. By adding the references for the include directory and the libs directly.

Hope this helps.

win32:INCLUDEPATH += C:\irrlicht-1.8\include
win32:LIBS += c:\irrlicht-1.8\lib\win32-gcc\libirrlicht.a

Answer 2

I found the cause! it was because I did not have installed the visualization library! the problem was that I had not checked the output of compiling the PCL library and it had said that it would not compile some modules because of dependency problems.
