Issues with 3D graph display

[Langelier]

Hi everyone,

I'm using a 3D graph in one of my VIs and I have issues with the display. See what it displays by yourself:

So, as you can see, the graph does not display properly the data. But one thing I know is that the data is sent properly, because when I copy the graph from LabVIEW and paste it in Paint, what I see is the graph displayed properly:

Does someone know what can cause the issue? I also have a similar problem with a 3D waterfall.

Hi Langelier,

What version of LabVIEW are you running and what type of video card do you have? It appears there was an issue with the 3D Picture Control in LabVIEW 2012 when using AMD video cards, but this has since been resolved in recent patches.

Here is a discussion forum thread concerning this issue.

I'm using LV 2011 with a basic intel g33/g31 express chipset family video card. One thing I forgot to mention is that this thing does not happen on other computers, including a 4 year old laptop so it doesn't take much power to display it.

One thing to do is check to make sure that your LabVIEW is fully updated.

Do you know if you are using 2011 SP1?

[Langelier]

I don't think I have the SP1, should I download it?

[Burrito]

I would run the NI Update Service by going to Program Files-> National Instruments-> NI Update Service and download any updates to your software.

It's also not a bad idea to try simple things like restarting LabVIEW and restarting your PC if you haven't done so already.

[Langelier]

Do I have an alternative solution if there's no NI Update Software on my computer?

You can always download updates from ni.com as well.

I also went through some documentation on known issues in LV 2011. I was able to find something interesting on this page:

3D Picture Controls can display transparently or crash LabVIEW on certain graphics cards

The 3D Picture Control is built on a OpenSceneGraph which uses OpenGL. Several reports of the 3D picture control crashing LabVIEW have been reported. In almost all cases it was an Intel integrated graphics card involved. This crash is caused by an incompatibility of the graphics hardware. Note: Many of the 3D Graphs use the 3D Picture Control

Some possible workarounds are:

• Update the video driver
• Turn on/off hardware acceleration
• Turn on Aero in Windows 7
• Turn off Aero in Windows 7

I would try these workarounds and see if any of them work for you.

Thank you, when I turned off Aero it worked so maybe the graphic card couldn't handle both Aero and the 3D graph display.
