My 3D Graph Display in HiQ 4.0 or 4.1 for Windows Is Blank (or Black) Primary Software: Other NI Software>>HiQPrimary Software Version: 4.1 Primary Software Fixed Version: N/A Secondary Software: N/A
Problem: The 3D graph display in my HiQ 4.0 or 4.1 notebook is blank (or black). Solution: This issue is likely related to your PC's video driver. The 3-D graph in HiQ 4.x for Windows leverages OpenGL, a 3D graphics standard that can rely either on your video hardware or software. Try each of the following suggestions in turn in an effort to correct the problem. When you test to see if the suggestion works, please examine an example file that draws a 3D graph, such as \examples\data visualization\data visualization.hiq . 1) Try toggling the "Use 3D hardware acceleration" option under File>>Preferences. After you make the change, stop and start HiQ to make sure that the change takes effect. 2) If you are running Windows 98 or Windows 95, try changing the Video acceleration feature to "None." To do this, go to the display settings page in your control panel and choose the Settings tab. Click the Advanced button, and on the next dialog, choose the Performance tab. Move the acceleration tab to the far left. 3) Try switching to a standard VGA video driver. If the 3D graph works, the problem is likely a bug in your video card driver; make sure that you have the latest driver for your video card. 4) Try switching color depth or display resolution. If the 3D graph works, the problem is likely a bug in your video card driver; make sure that you have the latest driver for your video card. Note: National Instruments does not support HiQ functionality on Mac OS in LabVIEW 7.0 and will no longer support HiQ functionality on all platforms after LabVIEW 7.0. If your application uses HiQ VIs, consider replacing them with the Analyze and Mathematics VIs. Refer to the LabVIEW Help for information about using the Analyze and Mathematics VIs. You access the LabVIEW Help by selecting Help»VI, Function, & How-To Help. Related Links: HiQ Product Page HiQ Support Attachments:
