    Default Q3DCamera Y axis rotation limit

    I am using Q3DSurface and found that Y rotation is limited to 0 - 90 degrees while X can go from 0 - 380. How can I get my Y rotation to 0- 360 so I can spin my surface in any direction my user wants. I thought this will be some limit in Q3DCamera assigned to Q3DSurface. I can not find the limits though. Anybody?

    Default Re: Q3DCamera Y axis rotation limit

    Hi,

    I had the same trouble, the settings of the Y rotation is private so I couldn't get free movement with my Q3DSurface.
    But the Q3DScatter allows this full movement ! So I just had to :
    - create a Q3DScatter,
    - permute the camera between the Q3DScatter and my Q3DSurface,
    - delete the Q3DScatter.

    Qt Code:
    1. Q3DScatter *myQ3DScatter = new Q3DScatter();
    2. Q3DSurface *myQ3DSurface = new Q3DSurface();
    3. Q3DCamera *cameraFromQ3DSurface = myQ3DSurface->scene()->activeCamera();
    4. myQ3DSurface->scene()->setActiveCamera( myQ3DScatter->scene()->activeCamera() );
    5. myQ3DScatter->scene()->setActiveCamera( cameraFromQ3DSurface );
    6. delete myQ3DScatter;
    To copy to clipboard, switch view to plain text mode 

    That works just fine for me

    Regards,
