Cannot build PCL against VTK with OpenGL2

[VictorLamoine]

How to reproduce

• Compile / install VTK with VTK_RENDERING_BACKEND = OpenGL2
• Compile PCL against this VTK version

Error

pcl/src/visualization/src/pcl_visualizer.cpp:87:38: fatal error: vtkOpenGLHardwareSupport.h: Aucun fichier ou dossier de ce type
 #include <vtkOpenGLHardwareSupport.h>

I created a big mesh with blender (8 060 918 points)

Ubuntu 14.04 with latest proprietary drivers

VTK with:	OpenGL	OpenGL2
Nvidia GTX 770	< 5 fps	> 60 fps
Nvidia Quadro K3000M	< 10 fps	< 10 fps + tearing

Note that OpenGL2 is now default in VTK trunk!
Given the outrageous performance improvement with newer graphic cards, we really should work on making PCL compatible with VTK+OpenGL2.

Help is appreciated because I'm not quite sure how to modify PCL code using OpenGL.

Sounds interesting. I'll try to have a look, but no guarantees...

I asked the VTK community:

I'll give it a try a little bit later but it doesn't look like an easy fix to apply!

There are plans to support VTK OpenGL2 backend?

[VictorLamoine]

The issue is here just for that, unfortunately what I tried did not work a the moment.
If you have time and skills to make the changes, pull requests are welcome!

[mcleary]

@VictorLamoine, I understand. I asked to see if there is anyone already working on this. I'll give it a try.

👍 for this, we have a similar issue on Arch Linux, where VTK 7.0 is now used with the OpenGL2 backend.

Fixed with #1534.
