Hi,
Was your student using QVTKWidget & old OpenGL backend?
Warm Regards

try updating the nvidia driver. One of my students has similar problem with nvidia drivers 350 series, after upgrading to 360 series everything works.

Ohh sorry, that system is fine in terms of OpenGL1 or OpenGL2 support (both on the intel GPU and the quadro) as long as the drivers are up to date. I suspect your issue may be related to which Qt widget is being used. There are folks on this list that have a lot of experience with Qt graphics issues and probably know the answer. Just not me :-)

Hi,
I have currently built VTK with OpenGL1 backend itself. On one of the system it is producing this error. So is there any other way to make sure that it works on that system? Following is the system configuration of that machine:
OS Name: Microsoft Windows 8.1 Pro
Version: 6.3.9600 Build 9600
OS Manufacturer: Microsoft Corporation
System Manufacturer: Dell Inc.
System Model: Precision T1700
System Type: x64-based PC
Processor Intel(R) Core(TM) i7-4790 CPU @ 3.60GHz, 3592 Mhz, 4 Core(s), 8 Logical Processor(s)
Installed Physical Memory (RAM): 32.0 GB
Total Virtual Memory: 36.7 GB
Display adapter: NVIDIA Quadro K620
The mailing list suggests to use QVTKWidget2 instead of QVTKWidget. Will this help me to solve the issue?
Thanks for your quick reply.
Warm Regards
Rakesh Patil

Any system with any configuration is pretty broad :-) If you want maximum portability at the cost of performance then make sure you build with the OpenGL1 backend. It will not run on every system, but it should work on most systems that are currently in use.

Hi,
How do I make sure that my VTK based application will work on any system with any configuration, without throwing this error message? Upgrading VTK 6.3 to the latest version will solve the issue, or should we try upgrading the NVidia driver card?
Warm Regards

The old OpenGL backend will work with OpenGL version 1.1, while the new OpenGL backend requires something closer to OpenGL version 2.1 to 3.2 (or later).
Windows only comes with OpenGL version 1.4 (a software renderer). It is up to the hardware providers to supply hardware drivers. Pretty much anything released by Nvidia/AMD/Intel in the past 5 years will support OpenGL 3.2 or later. Earlier than that and it becomes a bit more hit or miss.
Yes it depends on the graphics card. But since Intel started building in OpenGL support into their CPUs you can generally count on all recent (IvyBridge maybe SandyBridge or later) systems having sufficient OpenGL support for the new backend. There is a method renderWindow->SupportsOpenGL() that will test if a system meets the minimum requirements for the new backend,
I mentioned "one provided to VTK" because sometimes developers create their own opengl context (the context determines what level of OpenGL is provided) and then tell VTK to use it. That will only work if they give VTK a context that includes support for 3.2. Normally VTK creates its own context so it makes sure to create the right one.
I do not know much about Qt.
Thanks

Hi Ken Martin,
I believe I understood the core reason as why this message is displayed. I need some more details.
1) In what way OpenGL backend is different from the OpenGL2 backend for VTK 6.3. Knowing that QVTKWidget will be deprecated, what pre-requisite conditions needs to be considered to stick myself working with QVTKWidget on various system?
2) What exactly do you mean, when you say "one was provided to VTK that did not include opengl support". I guess all the latest Windows OS do come with OpenGL version greater than 1.1. So I think all the drivers must have OpenGL support right? Correct me if I am wrong.
3) Does this functionality really vary from one graphics card to another? I mean does it depend on the graphics card also? If so, how will I know whether my graphics card supports OpenGL backend or OpenGL2 backend?
Thank You
Warm Regards

I believe you gave the specs for your desktop as opposed to the laptop.
That message occurs on windows on the old OpenGL backend (and the OpenGL2 backend for VTK 6.3) It indicates that VTK tried to setup a device context for rendering but the device did not support opengl, either because VTK failed to find a suitable device or because on was provided to VTK that did not include opengl support.

Hi VTK users,
I am facing a strange issue. I am using QVTKWidget in my application and it works very well on my desktop computer. The same code when I try to compile on my laptop it throws me this error message:

I would like to know what are the scenarios in which VTK throws this message. Whether there is any dependency on various versions of Windows OS? I believe it should not be. Below is the system information where I get this error:
