  • Errors occur when running examples

    Dear Mike,

    When I running the OIV example HorizonGpuCompose,the following error occur,

    Inventor error in SoHeightFieldRender::GLRender():
    SoHeightFieldRender can't be rendered because
    your graphic card or driver is missing some needed
    OpenGL functionalities

    How to set display card parameter to run the program correctly?

    Best regards.

    Hi,
    That's unexpected. First, because the height field render code has been around for a long time and the only known issue is that some very old graphics boards don't support tesselation shaders (but there is a fallback for that). And second, because I don't find that error message anywhere in the SoHeightFieldRender code...

    Let's start with: What version of Open Inventor are you using and what graphics board are you using?
    Regards,
    Mike
