No 3D point cloud Widget after upgrade

Thanks for reporting this issue and providing a solution.

I suspect that an update of the libraries makes it necessary to link the libraries again. Thus, a recompilation is needed, which is also possible with just invoking make clean; make all in the build folder.

Here's the gdb result, no strange behaviour, I reckon it could be problem of Qt gui mapping issue, since the points are correctly loaded into the memory and rendered on GPU side.

Strange, when I open with QtCreator, it can successfully build with the Glow window...

I guess for anyone who meet this kind of problem, just do the following:

• install qtcreator by sudo apt install qtcreator
• open qtcreator and load the project by open the CMakeLists.txt
• click run button to build the program

Thanks for your reply, I actually did the clean process and even downloaded the repo and started over.

I think I can close this issue now :)

In the end, THANK FOR YOUR CONTRIBUTION!
